LO Cockpit questions
Need some expert guidance please.
We just set up a second BI system so now we have 2 BI systems that are connected to one ERP source system. We're working on a new project, which is being developed in the new BI system. One of the required datasources is the 2LIS_13_VDITM. This data source is also currently being used in the old system to extract data for another infocube (btw, data source in the old system is 3.x). We're using 7.0 in the new system. My question is, what do I need to do to set up the LO cockpit for data extraction for the new system/datasource. I don't want to affect the existing setup but not quite sure what to do for the new one?
I've read from this forum and got some procedures that calls for deleting and filling up set up tables and establishing the delta for extraction. This procedure is understood, but I want to know if I follow this process, will that affect the existing set up for the old system? Do I even need to delete and fill up the set up tables if they're currently being used right now? Can I just do an init with the new datasource?
Sorry for the many questions and I apologize if I'm breaking protocals. I have not worked with the LO Cockpit before. Please help. Any suggestions/guidance will be greatly appreciate.
Thanks in advance.
Deleting and filling the setup tables have nothing to do with the delta process, so have no fear with disrupting your current delta. What you need to do is find a quiet time to fill the setup tables so you can run an Init w/ data on your new BI system. This will setup another delta queue in RSA7, so there will be two delta queues (one for each BI system). The current V3 collection job in R/3 will add invoicing data to both delta queues, but you will have separate delta infopackages on your BI systems.
Hope this helps...

BI Administration Cockpit Question
Hi, Does anyone have any exposure to this yet? I have a few questions that I need answers to and I'm hoping the BI Administration Cockpit might be the answer instead of building from scratch.
1. Reports statistics of each process chain and related process chain process
- I need to know that my ODS activation started @ 10am actived 10,000 records and ended at 10:01 am. (how long it took).
- I need to know that my data load loaded 1,000 records and how long it took.
- I need to know that my rollup compressed x number of records and took how long.. Etc, Etc, Etc.
2. Need to compare the above statistics from a day to day perspective so that I can set up exceptions to be reported on.
If the BI Administration Cockpit can't provide me with this I'll have to write some abap process to go out and collect all of this and I'm sure that'll be quite a task.
Anyone have any suggestions how to collect this information so I can report on it?
Thanks,
Ken MurrayHello Kenneth,
BI admin cockpit has some trending reports. You might need to tweak the iViews / queries a bit but the real time stuff is quite neat.
If you ever end up writing the ABAP to do what you want, take a look in this month's issue of BWExpert first.
Hope this helps,

Hi,
We are trying to activate the admin cockpit thru ABAP "RSTCC_ACTIVATE_ADMIN_COCKPIT" and have couple of question.
1. Activate SAPI DataSources ( wat is mean by this)
2. Activate MySelf Source sytem (My source system is already in active, does this reactivate again
Force MySelf System activation
3. Replicate DataSources ( Is this relevant for only Techincal content DS?)
Force DataSource Replication
Repair Missing Infopackage
4. Activate Techincal content
only simulaiton
Is there any webtemplate behind the cockpit?
AngeliHi,
yes there are webtemplates behind the cockpit. It is running in the portal. The presentation 'SAP NetWeaver BI Administration Cockpit' will show. For the admin cockpit you have to activate technical BI content.
Check this articles/threads to get the information:

Assign Driver Vehicle in DSD Connector Cockpit Question?
Hi All,
We are implementing DSD with MDSD functionality on it. We had created Driver master data (As Customer Masterdata) and Vehicle master data ( as Equipment master) in the DSD backend. We are done with all the DSD backend , DSD connector & MI server configurations. When we go to DSD connector cockpit transation /DSD/ME_CPT we are able to see our Mobile device when we do F4 on the Mobile ID column but when we do a F4 on Driver and Vehicle columns we are not able to see the Driver and Vehicle master data that we had created for DSD project.
Is there any configuration we need to do so that the Driver and Vehicle master data will show up in the DSD connector cockpit transaction????
Thanks for your help in advance.
Thanks,
GreetsonHi All,
During my investigation I found that DSD Connector Cockpit is reading the data for Driver and vehicle from the table "/DSD/RP_DRVTPLST and /DSD/_RP_DRVLIC.
I am not sure How we can maintain entries in these tables. Looks like there are no tabele maintenance for these tables.??
Thanks,

How to display Selection screen on Web for RSCRM_BAPI
HI,
For a customer we want to create the possibility to extract data from BI2004s to other systems, therefore we want to use RSCRM_BAPI.
Thing is that we want to provide the possibility for them to enter selectioncriteria, but we don't want them to log on using the Gui.
We want to use the VC to create an interface cockpit.
question is how we can allow users to use selectioncriteria but:
variants can not be used
TVARV can not be used
is there any way to capture the selection screen and to display it on the web/VC?
Anyone ever did this?
Tnx
rogierGili.
thank you for your quick reply,.
Reason why we are looking into the RSCRM_BAPI is due to the layout
requirements of the extract. the recieving systems requires specific layouts. If we do this with the infospoke we will have to use a BADI to perfom complex transformations which will need additional knowlegde (of BADI's) of the support organisation whereas with RSCRM_BAPI they can adjust the query.
and as far as i know you can not define the variable input via the web for open hub.

Now that I've finally got Cockpit running with SAP support's assistance I have two further questions I was hoping that someone here could answer:
1) Is it possible to get cockpit running on multiple companies on the same server?
2) Can I switch databases Cockpit is connected to?
thanks,
chrisChris,
Using the Cockpit is defined in the Company Setup information per Business One company (Db). The installation of B1ic which runs the Dashboards sets up one of the databases you choose during installation. If you wish to run dashboards in multiple companies, you will need to configure the SLD for the database in B1ic as well as turn on the Cockpit in each Db.

LO cockpit extraction - data flow question
This question is related with the LO cockpit extraction.
Are update tables are meant to be the same as set tables or
are they different?
can anybody provide a highlevel data flow for the logistics data
using LO cockpit from R3 to BW
please correct / enhance the below data flow for different methods of LO delta updates as i assume
and inculude the set up table where it fits.
(for direct update)
R3 db talbes -> delta queue -> extract structure -> transfer structure -> infosource -> data target
(for queued delta)
R3 db talbes -> extraction queue -> delta queue -> extract structure -> transfer structure -> infosource -> data target
(for unserialized V3 update)
R3 db talbes -> postings to update tables -> delta queue -> extract structure -> transfer structure -> infosource -> data target
I also want to know where does the delta queue reside - in R3 or in BW? Can the content of delta queue be viewed?
Thanks for ur help - i will give full points for your input.
akCheck the diagram in links below. It clearly identifies the data flow and whether the component is in R3 or BW.

KPI cockpit : modelling question
Hi,
We are making a KPI cockpit in the Visual Composer based on BW keyfigures. In our application we have 4 tables in which we show the keyfigures based on different queries. Thus in one table we show multiple keyfigures from multiple queries thanks to the "union" operator. In the first column we show the different keyfigures (from different queries), in the next colums we show the values and trends
This is how one of our table looks
Key figure Value Trend Exception
Net Value 100 Down Red
Weight 20 Kg Up Green
Headcount 25 Same Yellow
The keyfigures above originate from different queries (co-pa, hr,...)
But, now we'd like to offer drilldown possibility from the tables to detail queries and/or webreports but our biggest problem is that the target report is fully dependend on the keyfigure row that is selected from the table. Is it possible to create a model in VC in which the target report choosen is dependend on a certain row that is selected in the table ?
thanks for your feedbackHi Double U,
I'm not sure whether I fully understood your problem. Getting a row index from a table is not possible (e.g. row 3 is selected). Still you can distinguish by using the table field "Key_figure" in guard conditions. I don't know how you plan to invoke your reports, but you might do the following. Drag four connectors from the out-port of your table. An event listener for the "select"-event should be generated automatically. For every connector you define a special guard condition. For example:
"IF(@key_figure=="Net Value",true,false)"
would be the guard condition on the connector to your Detail Report on Net Value.
In case this is not what you plan to do, please provide us with more details.
Best regards,

2. What are the steps involved in LO Extraction?
• The steps are:
o RSA5 Select the DataSources
o LBWE Maintain DataSources and Activate Extract Structures
o LBWG Delete Setup Tables
o 0LI*BW Setup tables
o RSA3 Check extraction and the data in Setup tables
o LBWQ Check the extraction queue
o LBWF Log for LO Extract Structures
o RSA7 BW Delta
Queue Monitor
3. How to create a connection with LIS InfoStructures?
• LBW0 Connecting LIS InfoStructures to BW
4. What is the difference between ODS and InfoCube and MultiProvider?
• ODS: Provides granular data, allows overwrite and data is in transparent
tables, ideal for drilldown and RRI.
• CUBE: Follows the star schema, we can only append data, ideal for primary
reporting.
• MultiProvider: Does not have physical data. It allows to access data from
different InfoProviders (Cube, ODS, InfoObject). It is also preferred for
reporting.
5. What are Start routines, Transfer routines and Update routines?
• Start Routines: The start routine is run for each DataPackage after the data
has been written to the PSA and before the transfer rules have been executed.
It allows complex computations for a key figure or a characteristic. It has no
return value. Its purpose is to execute preliminary calculations and to store
them in global DataStructures. This structure or table can be accessed in the
other routines. The entire DataPackage in the transfer structure format is used
as a parameter for the routine.
• Transfer / Update Routines: They are defined at the InfoObject level. It is
like the Start Routine. It is independent of the DataSource. We can use this to
define Global Data and Global Checks.
6. What is the difference between start routine and update routine, when, how
and why are they called?
• Start routine can be used to access InfoPackage while update routines are
used while updating the Data Targets.
7. What is the table that is used in start routines?
• Always the table structure will be the structure of an ODS or InfoCube. For
example if it is an ODS then active table structure will be the table.
8. Explain how you used Start routines in your project?
• Start routines are used for mass processing of records. In start routine all
the records of DataPackage is available for processing. So we can process all
these records together in start routine. In one of scenario, we wanted to apply
size % to the forecast data. For example if material M1 is forecasted to say
100 in May. Then after applying size %(Small 20%, Medium 40%, Large 20%, Extra
Large 20%), we wanted to have 4 records against one single record that is
coming in the info package. This is achieved in start routine.
9. What are Return Tables?
• When we want to return multiple records, instead of single value, we use the
return table in the Update Routine. Example: If we have total telephone expense
for a Cost Center, using a return table we can get
expense per employee.
10. How do start routine and return table synchronize with each other?
• Return table is used to return the Value following the execution of start
routine
11. What is the difference
between V1, V2 and V3 updates?
• V1 Update: It is a Synchronous update. Here the Statistics update is carried
out at the same time as the document update (in the application
tables).
• V2 Update: It is an Asynchronous update. Statistics update and the Document
update take place as different tasks.
o V1 & V2 don't need scheduling.
• Serialized V3 Update: The V3 collective update must be scheduled as a job
(via LBWE). Here, document data is collected in the order it was created and
transferred into the BW as a batch job. The transfer sequence may not be the
same as the order in which the data was created in all scenarios. V3 update
only processes the update data that is successfully processed with the V2
update.
12. What is compression?
• It is a process used to delete the Request IDs and this saves space.
13. What is Rollup?
• This is used to load new DataPackages (requests) into the InfoCube
aggregates. If we have not performed a rollup then the new InfoCube data will
not be available while reporting on the aggregate.
14. What is table partitioning and what are the benefits of partitioning in an
InfoCube?
• It is the method of dividing a table which would enable a quick reference.
SAP uses fact file partitioning to improve performance. We can partition only
at 0CALMONTH or 0FISCPER. Table partitioning helps to run the report faster as
data is stored in the relevant partitions. Also table maintenance becomes
easier. Oracle,
Informix, IBM DB2/390 supports table partitioning while SAP DB, Microsoft SQL
Server, IBM DB2/400 do not support table portioning.
15. How many extra partitions are created and why?
• Two partitions are created for date before the begin date and after the end
date.
16. What are the options available in transfer rule?
• InfoObject
• Constant
• Routine
• Formula
17. How would you optimize the dimensions?
• We should define as many dimensions as possible and we have to take care that
no single dimension crosses more than 20% of the fact table size.
18. What are Conversion Routines for units and currencies in the update rule?
• Using this option we can write ABAP
code for Units / Currencies conversion. If we enable this flag then unit of Key
Figure appears in the ABAP code as an additional parameter. For example, we can
convert units in Pounds to Kilos.
19. Can an InfoObject be an InfoProvider, how and why?
• Yes, when we want to report on Characteristics or Master Data. We have to
right click on the InfoArea and select "Insert characteristic as data
target". For example, we can make 0CUSTOMER as an InfoProvider and report
on it.
20. What is Open Hub Service?
• The Open Hub Service enables us to distribute data from an SAP BW system into
external Data Marts, analytical applications, and other applications. We can
ensure controlled distribution using several systems. The central object for
exporting data is the InfoSpoke. We can define the source and the target object
for the data. BW becomes a hub of an enterprise data warehouse.
The distribution of data becomes clear through central monitoring from the
distribution status in the BW system.
21. How do you transform Open
Hub Data?
• Using BADI we can transform Open Hub Data according to the destination
requirement.
22. What is ODS?
• Operational DataSource is used for detailed storage of data. We can overwrite
data in the ODS. The data is stored in transparent tables.
23. What are BW Statistics and what is its use?
• They are group of Business Content InfoCubes which are used to measure
performance for Query and Load Monitoring. It also shows the usage of
aggregates, OLAP and Warehouse management
http://www.ittestpapers.com/articles/713/3/SAP-BW-Interview-Questions---Part-A/Page3.html
Communication Structure and Transfer
rules
• Create and InfoPackage
• Load Data
25. What are the delta options available when you load from flat file?
• The 3 options for Delta Management with Flat Files:
o Full Upload
o New Status for Changed records (ODS Object only)
o Additive Delta (ODS Object & InfoCube)
Q) Under which menu path is the Test Workbench to be found, including in
earlier Releases?
The menu path is: Tools - ABAP Workbench - Test - Test Workbench.
Q) I want to delete a BEx query that is in Production system through request. Is
anyone aware about it?
A) Have you tried the RSZDELETE transaction?
Q) Errors while monitoring process chains.
A) During data loading. Apart from them, in process chains you add so many
process types, for example after loading data into Info Cube, you rollup data
into aggregates, now this rolling up of data into aggregates is a process type
which you keep after the process type for loading data into Cube. This rolling
up into aggregates might fail.
Another one is after you load data into ODS, you activate ODS data (another
process type) this might also fail.
Q) In Monitor----- Details (Header/Status/Details) à Under Processing (data
packet): Everything OK à Context menu of Data Package 1 (1 Records): Everything
OK ---- Simulate update. (Here we can debug update rules or transfer rules.)
SM50 à Program/Mode à Program à Debugging & debug this work process.
Q) PSA Cleansing.
A) You know how to edit PSA. I don't think you can delete single records. You
have to delete entire PSA data for a request.
Q) Can we make a datasource to support delta.
A) If this is a custom (user-defined) datasource you can make the datasource
delta enabled. While creating datasource from RSO2, after entering datasource
name and pressing create, in the next screen there is one button at the top,
which says generic delta. If you want more details about this there is a
chapter in Extraction book, it's in last pages u find out.
Generic delta services: -
Supports delta extraction for generic extractors according to:
Time stamp
Calendar day
Numeric pointer, such as document number & counter
Only one of these attributes can be set as a delta attribute.
Delta extraction is supported for all generic extractors, such as tables/views,
SAP Query and function modules
The delta queue (RSA7) allows you to monitor the current status of the delta
attribute
Q) Workbooks, as a general rule, should be transported with the
role.
Here are a couple of scenarios:
1. If both the workbook and its role have been previously transported, then the
role does not need to be part of the transport.
2. If the role exists in both dev and the target system but the workbook has
never been transported, and then you have a choice of transporting the role
(recommended) or just the workbook. If only the workbook is transported, then
an additional step will have to be taken after import: Locate the WorkbookID
via Table RSRWBINDEXT (in Dev and verify the same exists in the target system)
and proceed to manually add it to the role in the target system via Transaction
Code PFCG -- ALWAYS use control c/control v copy/paste for manually adding!
3. If the role does not exist in the target system you should transport both
the role and workbook. Keep in mind that a workbook is an object unto itself
and has no dependencies on other objects. Thus, you do not receive an error
message from the transport of 'just a workbook' -- even though it may not be
visible, it will exist (verified via Table RSRWBINDEXT).
Overall, as a general rule, you should transport roles with workbooks.
Q) How much time does it take to extract 1 million (10 lackhs) of records into
an infocube?
A. This depends, if you have complex coding in update rules it will take longer
time, or else it will take less than 30 minutes.
Q) What are the five ASAP Methodologies?
A: Project plan, Business Blue print, Realization, Final preparation & Go-Live - support.
1. Project Preparation: In this phase, decision makers define clear project
objectives and an efficient decision making process ( i.e. Discussions with the
client, like what are his needs and requirements etc.). Project managers
will be involved in this phase (I guess).
A Project Charter is issued and an implementation strategy is outlined in this
phase.
2. Business Blueprint: It is a detailed documentation of your company's
requirements. (i.e. what are the objects we need to develop are modified
depending on the client's requirements).
3. Realization: In this only, the implementation of the project takes place (development
of objects etc) and we are involved in the project from here only.
4. Final Preparation: Final preparation before going live i.e. testing,
conducting pre-go-live, end user training etc.
End user training is given that is in the client site you train them how to
work with the new environment, as they are new to the technology.
5. Go-Live & support: The project has gone live and it is into production.
The Project team will be supporting the end users.
Q) What is landscape of R/3 & what is landscape of BW. Landscape of R/3 not
sure.
Then Landscape of b/w: u have the development system, testing system, production system
Development system: All the implementation part is done in this sys. (I.e.,
Analysis of objects developing, modification etc) and from here the objects are
transported to the testing system, but before transporting an initial test
known as Unit testing
(testing of objects) is done in the development sys.
Testing/Quality system: quality check is done in this system and integration
testing is done.
Production system: All the extraction part takes place in this sys.
Q) How do you measure the size of infocube?
A: In no of records.
Q). Difference between infocube and ODS?
A: Infocube is structured as star schema (extended) where a fact table is
surrounded by different dim table that are linked with DIM'ids. And the data
wise, you will have aggregated data in the cubes. No overwrite functionality
ODS is a flat structure (flat table) with no star schema concept and which will
have granular data (detailed level). Overwrite functionality.
Flat file
datasources does not support 0recordmode in extraction.
x before, -after, n new, a add, d delete, r reverse
Q) Difference between display attributes and navigational attributes?
A: Display attribute is one, which is used only for display purpose in the
report. Where as navigational attribute is used for drilling down in the
report. We don't need to maintain Navigational attribute in the cube as a
characteristic (that is the advantage) to drill down.
Q. SOME DATA IS UPLOADED TWICE INTO INFOCUBE. HOW TO CORRECT IT?
A: But how is it possible? If you load it manually twice, then you can delete
it by requestID.
Q. CAN U ADD A NEW FIELD AT THE ODS LEVEL?
Sure you can. ODS is nothing but a table.
Q. CAN NUMBER OF DATASOURCES HAVE ONE INFOSOURCE?
A) Yes of course. For example, for loading text and hierarchies we use
different data sources but the same InfoSource.
Q. BRIEF THE DATAFLOW IN BW.
A) Data flows from transactional system to analytical system (BW). DataSources
on the transactional system needs to be replicated on BW side and attached to
infosource and update rules respectively.
Q. CURRENCY CONVERSIONS CAN BE WRITTEN IN UPDATE RULES. WHY NOT IN TRANSFER
RULES?
Q) WHAT IS PROCEDURE TO UPDATE DATA INTO DATA TARGETS?
FULL and DELTA.
Q) AS WE USE Sbwnn, sbiw1, sbiw2 for delta update in LIS THEN
WHAT IS THE PROCEDURE IN LO-COCKPIT?
No LIS in LO cockpit. We will have datasources and can be maintained (append
fields). Refer white paper
on LO-Cockpit extractions.
Q) Why we delete the setup tables (LBWG) & fill them (OLI*BW)?
A) Initially we don't delete the setup tables but when we do change in extract
structure we go for it. We r changing the extract structure right, that means
there are some newly added fields in that which r not before. So to get the
required data ( i.e.; the data which is required is taken and to avoid
redundancy) we delete n then fill the setup tables.
To refresh the statistical data.
The extraction set up reads the dataset that you want to process such as,
customers orders with the tables like VBAK, VBAP) & fills the relevant communication
structure with the data. The data is stored in cluster
tables from where it is read when the initialization is run. It is important
that during initialization phase, no one generates or modifies application
data, at least until the tables can be set up.
Q) SIGNIFICANCE of ODS?
It holds granular data (detailed level).
Q) WHERE THE PSA DATA IS STORED?
In PSA table.
Q) WHAT IS DATA SIZE?
The volume of data one data target holds (in no. of records)
Q) Different types of INFOCUBES.
Basic, Virtual (remote, sap remote and multi)
Virtual Cube is used for example, if you consider railways reservation all the
information has to be updated online. For designing the Virtual cube you have
to write the function module that is linking to table, Virtual cube it is like
a the structure, when ever the table is updated the virtual cube will fetch the
data from table and display report Online... FYI.. you will get the information
: https://www.sdn.sap.com/sdn
/index.sdn and search for Designing Virtual Cube and you will get
a good material designing the Function Module
Q) INFOSET QUERY.
Can be made of ODS's and Characteristic InfoObjects with masterdata.
Q) IF THERE ARE 2 DATASOURCES HOW MANY TRANSFER STRUCTURES ARE THERE.
In R/3 or in BW? 2 in R/3 and 2 in BW
Q) ROUTINES?
Exist in the InfoObject, transfer routines, update routines and start routine
Q) BRIEF SOME STRUCTURES USED IN BEX.
Rows and Columns, you can create structures.
Q) WHAT ARE THE DIFFERENT VARIABLES USED IN BEX?
Different Variable's are Texts, Formulas, Hierarchies, Hierarchy nodes &
Characteristic values.
Variable Types are
Manual entry /default value
Replacement path
SAP exit
Customer exit
Authorization
Q) HOW MANY LEVELS YOU CAN GO IN REPORTING?
You can drill down to any level by using Navigational attributes and jump
targets.
Q) WHAT ARE INDEXES?
Indexes are data base indexes, which help in retrieving data fastly.
Q) DIFFERENCE BETWEEN 2.1 AND 3.X VERSIONS.
Help! Refer documentation
Q) IS IT NESSESARY TO INITIALIZE EACH TIME THE DELTA UPDATE IS USED?
No.
Q) WHAT IS THE SIGNIFICANCE OF KPI'S?
KPI's indicate the performance of a company. These are key figures
Q) AFTER THE DATA EXTRACTION
WHAT IS THE IMAGE POSITION.
After image (correct me if I am wrong)
Q) REPORTING AND RESTRICTIONS.
Help! Refer documentation.
Q) TOOLS USED FOR PERFORMANCE TUNING.
ST22, Number ranges, delete indexes before load. Etc
Q) PROCESS CHAINS: IF U has USED IT THEN HOW WILL U SCHEDULING DATA DAILY.
There should be some tool to run the job daily (SM37 jobs)
Q) AUTHORIZATIONS.
Profile generator
Q) WEB REPORTING.
What are you expecting??
Q) CAN CHARECTERSTIC INFOOBJECT CAN BE INFOPROVIDER.
Of course
Q) PROCEDURES OF REPORTING ON MULTICUBES
Refer help. What are you expecting? MultiCube works on Union condition
Q) EXPLAIN TRANPSORTATION OF OBJECTS?
Dev---àQ and Dev-------àP
Q) What types of partitioning are there for BW?
There are two Partitioning Performance aspects for BW (Cube & PSA)
Query Data Retrieval
Performance Improvement:
Partitioning by (say) Date Range improves data retrieval by making best use of
database [data range] execution plans and indexes (of say Oracle database engine).
B) Transactional Load Partitioning Improvement:
Partitioning based on expected load volumes and data element sizes. Improves
data loading into PSA and Cubes by infopackages (Eg. without timeouts).
Q) How can I compare data in R/3 with data in a BW Cube after the daily delta
loads? Are there any standard procedures for checking them or matching the
number of records?
A) You can go to R/3 TCode RSA3 and run the extractor. It will give you the
number of records extracted. Then go to BW Monitor to check the number of
records in the PSA and check to see if it is the same & also in the monitor
header tab.
A) RSA3 is a simple extractor checker program that allows you to rule out
extracts problems in R/3. It is simple to use, but only really tells you if the
extractor works. Since records that get updated into Cubes/ODS structures are
controlled by Update Rules, you will not be able to determine what is in the
Cube compared to what is in the R/3 environment. You will need to compare
records on a 1:1 basis against records in R/3 transactions for the functional
area in question. I would recommend enlisting the help of the end user community
to assist since they presumably know the data.
To use RSA3, go to it and enter the extractor ex: 2LIS_02_HDR. Click execute
and you will see the record count, you can also go to display that data. You
are not modifying anything so what you do in RSA3 has no effect on data quality
afterwards. However, it will not tell you how many records should be expected
in BW for a given load. You have that information in the monitor RSMO during
and after data loads. From RSMO for a given load you can determine how many
records were passed through the transfer rules from R/3, how many targets were
updated, and how many records passed through the Update Rules. It also gives
you error messages from the PSA.
Q) Types of Transfer Rules?
A) Field to Field mapping, Constant, Variable & routine.
Q) Types of Update Rules?
A) (Check box), Return table
Q) Transfer Routine?
A) Routines, which we write in, transfer rules.
Q) Update Routine?
A) Routines, which we write in Update rules
Q) What is the difference between writing a routine in transfer rules and
writing a routine in update rules?
A) If you are using the same InfoSource to update data in more than one data
target its better u write in transfer rules because u can assign one InfoSource
to more than one data target & and what ever logic u write in update rules
it is specific to particular one data target.
Q) Routine with Return Table.
A) Update rules generally only have one return value. However, you can create a
routine in the tab strip key figure calculation, by choosing checkbox Return
table. The corresponding key figure routine then no longer has a return value,
but a return table. You can then generate as many key figure values, as you
like from one data record.
Q) Start routines?
A) Start routines u can write in both updates rules and transfer rules, suppose
you want to restrict (delete) some records based on conditions before getting
loaded into data targets, then you can specify this in update rules-start
routine.
Ex: - Delete Data_Package ani ante it will delete a record based on the
condition
Q) X & Y Tables?
X-table = A table to link material SIDs with SIDs for time-independent
navigation attributes.
Y-table = A table to link material SIDs with SIDS for time-dependent navigation
attributes.
There are four types of sid tables
X time independent navigational attributes sid tables
Y time dependent navigational attributes sid tables
H hierarchy sid tables
I hierarchy structure sid tables
Q) Filters & Restricted Key figures (real time example)
Restricted KF's u can have for an SD cube: billed quantity, billing value, no:
of billing documents as RKF's.
Q) Line-Item Dimension (give me an real time example)
Line-Item Dimension: Invoice no: or Doc no: is a real time example
Q) What does the number in the 'Total' column in Transaction RSA7 mean?
A) The 'Total' column displays the number of LUWs that were written in the
delta queue and that have not yet been confirmed. The number includes the LUWs
of the last delta request (for repetition of a delta request) and the LUWs for
the next delta request. A LUW only disappears from the RSA7 display when it has
been transferred to the BW System and a new delta request has been received
from the BW System.
Q) How to know in which table (SAP BW) contains Technical Name / Description
and creation data of a particular Reports. Reports that are created using BEx
Analyzer.
A) There is no such table in BW if you want to know such details while you are
opening a particular query press properties button you will come to know all
the details that you wanted.
You will find your information about technical names and description about
queries in the following tables. Directory of all reports (Table RSRREPDIR) and
Directory of the reporting component elements (Table RSZELTDIR) for workbooks
and the connections to queries check Where- used list for reports in workbooks
(Table RSRWORKBOOK) Titles of Excel Workbooks in InfoCatalog (Table
RSRWBINDEXT)
Q) What is a LUW in the delta queue?
A) A LUW from the point of view of the delta queue can be an individual
document, a group of documents from a collective run or a whole data packet of
an application
extractor.
Q) Why does the number in the 'Total' column in the overview screen of
Transaction RSA7 differ from the number of data records that is displayed when
you call the detail view?
A) The number on the overview screen corresponds to the total of LUWs (see also
first question) that were written to the qRFC queue and that have not yet been
confirmed. The detail screen displays the records contained in the LUWs. Both,
the records belonging to the previous delta request and the records that do not
meet the selection conditions of the preceding delta init requests are filtered
out. Thus, only the records that are ready for the next delta request are
displayed on the detail screen. In the detail screen of Transaction RSA7, a
possibly existing customer exit is not taken into account.
Q) Why does Transaction RSA7 still display LUWs on the overview screen after
successful delta loading?
A) Only when a new delta has been requested does the source system learn that
the previous delta was successfully loaded to the BW System. Then, the LUWs of
the previous delta may be confirmed (and also deleted). In the meantime, the
LUWs must be kept for a possible delta request repetition. In particular, the
number on the overview screen does not change when the first delta was loaded
to the BW System.
Q) Why are selections not taken into account when the delta queue is filled?
A) Filtering according to selections takes place when the system reads from the
delta queue. This is necessary for reasons of performance.
Q) Why is there a DataSource with '0' records in RSA7 if delta exists and has
also been loaded successfully?
It is most likely that this is a DataSource that does not send delta data to
the BW System via the delta queue but directly via the extractor (delta for
master data using ALE change pointers). Such a DataSource should not be
displayed in RSA7. This error is corrected with BW 2.0B Support Package 11.
Q) Do the entries in table ROIDOCPRMS have an impact on the performance of the
loading procedure from the delta queue?
A) The impact is limited. If performance problems are related to the loading
process from the delta queue, then refer to the application-specific notes (for
example in the CO-PA area, in the logistics cockpit area and so on).
Caution: As of Plug In 2000.2 patch 3 the entries in table ROIDOCPRMS are as
effective for the delta queue as for a full update. Please note, however, that
LUWs are not split during data loading for consistency reasons. This means that
when very large LUWs are written to the DeltaQueue, the actual package size may
differ considerably from the MAXSIZE and MAXLINES parameters.
Q) Why does it take so long to display the data in the delta queue (for example
approximately 2 hours)?
A) With Plug In 2001.1 the display was changed: the user has the option of
defining the amount of data to be displayed, to restrict it, to selectively
choose the number of a data record, to make a distinction between the 'actual'
delta data and the data intended for repetition and so on.
Q) What is the purpose of function 'Delete data and meta data in a queue' in
RSA7? What exactly is deleted?
A) You should act with extreme caution when you use the deletion function in
the delta queue. It is comparable to deleting an InitDelta in the BW System and
should preferably be executed there. You do not only delete all data of this
DataSource for the affected BW System, but also lose the entire information
concerning the delta initialization. Then you can only request new deltas after
another delta initialization.
When you delete the data, the LUWs kept in the qRFC queue for the corresponding
target system are confirmed. Physical deletion only takes place in the qRFC
outbound queue if there are no more references to the LUWs.
The deletion function is for example intended for a case where the BW System,
from which the delta initialization was originally executed, no longer exists
or can no longer be accessed.
Q) Why does it take so long to delete from the delta queue (for example half a
day)?
A) Import PlugIn 2000.2 patch 3. With this patch the performance during
deletion is considerably improved.
Q) Why is the delta queue not updated when you start the V3 update in the
logistics cockpit area?
A) It is most likely that a delta initialization had not yet run or that the
delta initialization was not successful. A successful delta initialization (the
corresponding request must have QM status 'green' in the BW System) is a
prerequisite for the application data being written in the delta queue.
Q) What is the relationship between RSA7 and the qRFC monitor (Transaction
SMQ1)?
A) The qRFC monitor basically displays the same data as RSA7. The internal
queue name must be used for selection on the initial screen of the qRFC
monitor. This is made up of the prefix 'BW, the client and the short name of
the DataSource. For DataSources whose name are 19 characters long or shorter,
the short name corresponds to the name of the DataSource. For DataSources whose
name is longer than 19 characters (for delta-capable DataSources only possible
as of PlugIn 2001.1) the short name is assigned in table ROOSSHORTN.
In the qRFC monitor you cannot distinguish between repeatable and new LUWs.
Moreover, the data of a LUW is displayed in an unstructured manner there.
Q) Why are the data in the delta queue although the V3 update was not started?
A) Data was posted in background. Then, the records are updated directly in the
delta queue (RSA7). This happens in particular during automatic goods receipt
posting (MRRS). There is no duplicate transfer of records to the BW system. See
Note 417189.
Q) Why does button 'Repeatable' on the RSA7 data details screen not only show
data loaded into BW during the last delta but also data that were newly added,
i.e. 'pure' delta records?
A) Was programmed in a way that the request in repeat mode fetches both
actually repeatable (old) data and new data from the source system.
Q) I loaded several delta inits with various selections. For which one is the
delta loaded?
A) For delta, all selections made via delta inits are summed up. This means, a
delta for the 'total' of all delta initializations is loaded.
Q) How many selections for delta inits are possible in the system?
A) With simple selections (intervals without complicated join conditions or
single values), you can make up to about 100 delta inits. It should not be
more.
With complicated selection conditions, it should be only up to 10-20 delta
inits.
Reason: With many selection conditions that are joined in a complicated way,
too many 'where' lines are generated in the generated ABAP
source code that may exceed the memory limit.
Q) I intend to copy the source system, i.e. make a client copy. What will
happen with may delta? Should I initialize again after that?
A) Before you copy a source client or source system, make sure that your deltas
have been fetched from the DeltaQueue into BW and that no delta is pending.
After the client copy, an inconsistency might occur between BW delta tables and
the OLTP delta tables as described in Note 405943. After the client copy, Table
ROOSPRMSC will probably be empty in the OLTP since this table is
client-independent. After the system copy, the table will contain the entries
with the old logical system name that are no longer useful for further delta
loading from the new logical system. The delta must be initialized in any case
since delta depends on both the BW system and the source system. Even if no
dump 'MESSAGE_TYPE_X' occurs in BW when editing or creating an InfoPackage, you
should expect that the delta have to be initialized after the copy.
Q) Is it allowed in Transaction SMQ1 to use the functions for manual control of
processes?
A) Use SMQ1 as an instrument for diagnosis and control only. Make changes to BW
queues only after informing the BW Support or only if this is explicitly
requested in a note for component 'BC-BW' or 'BW-WHM-SAPI'.
Q) Despite of the delta request being started after completion of the
collective run (V3 update), it does not contain all documents. Only another
delta request loads the missing documents into BW. What is the cause for this
"splitting"?
A) The collective run submits the open V2 documents for processing to the task
handler, which processes them in one or several parallel update processes in an
asynchronous way. For this reason, plan a sufficiently large "safety time
window" between the end of the collective run in the source system and the
start of the delta request in BW. An alternative solution where this problem
does not occur is described in Note 505700.
Q) Despite my deleting the delta init, LUWs are still written into the
DeltaQueue?
A) In general, delta initializations and deletions of delta inits should always
be carried out at a time when no posting takes place. Otherwise, buffer
problems may occur: If a user started the internal mode at a time when the
delta initialization was still active, he/she posts data into the queue even
though the initialization had been deleted in the meantime. This is the case in
your system.
Q) In SMQ1 (qRFC Monitor) I have status 'NOSEND'. In the table TRFCQOUT, some
entries have the status 'READY', others 'RECORDED'. ARFCSSTATE is 'READ'. What
do these statuses mean? Which values in the field 'Status' mean what and which
values are correct and which are alarming? Are the statuses BW-specific or
generally valid in qRFC?
A) Table TRFCQOUT and ARFCSSTATE: Status READ means that the record was read
once either in a delta request or in a repetition of the delta request.
However, this does not mean that the record has successfully reached the BW
yet. The status READY in the TRFCQOUT and RECORDED in the ARFCSSTATE means that
the record has been written into the DeltaQueue and will be loaded into the BW
with the next delta request or a repetition of a delta. In any case only the
statuses READ, READY and RECORDED in both tables are considered to be valid.
The status EXECUTED in TRFCQOUT can occur temporarily. It is set before
starting a DeltaExtraction for all records with status READ present at that
time. The records with status EXECUTED are usually deleted from the queue in
packages within a delta request directly after setting the status before
extracting a new delta. If you see such records, it means that either a process
which is confirming and deleting records which have been loaded into the BW is
successfully running at the moment, or, if the records remain in the table for
a longer period of time with status EXECUTED, it is likely that there are
problems with deleting the records which have already been successfully been
loaded into the BW. In this state, no more deltas are loaded into the BW. Every
other status is an indicator for an error or an inconsistency. NOSEND in SMQ1
means nothing (see note 378903).
The value 'U' in field 'NOSEND' of table TRFCQOUT is discomforting.
Q) The extract structure was changed when the DeltaQueue was empty. Afterwards
new delta records were written to the DeltaQueue. When loading the delta into
the PSA, it shows that some fields were moved. The same result occurs when the
contents of the DeltaQueue are listed via the detail display. Why are the data
displayed differently? What can be done?
Make sure that the change of the extract structure is also reflected in the
database and that all servers are synchronized. We recommend to reset the
buffers using Transaction $SYNC. If the extract structure change is not
communicated synchronously to the server where delta records are being created,
the records are written with the old structure until the new structure has been
generated. This may have disastrous consequences for the delta.
When the problem occurs, the delta needs to be re-initialized.
Q) How and where can I control whether a repeat delta is requested?
A) Via the status of the last delta in the BW Request Monitor. If the request
is RED, the next load will be of type 'Repeat'. If you need to repeat the last
load for certain reasons, set the request in the monitor to red manually. For
the contents of the repeat see Question 14. Delta requests set to red despite
of data being already updated lead to duplicate records in a subsequent repeat,
if they have not been deleted from the data targets concerned before.
Q) As of PI 2003.1, the Logistic Cockpit offers various types of update
methods. Which update method is recommended in logistics? According to which
criteria should the decision be made? How can I choose an update method in
logistics?
See the recommendation in Note 505700.
Q) Are there particular recommendations regarding the data volume the
DeltaQueue may grow to without facing the danger of a read failure due to
memory problems?
A) There is no strict limit (except for the restricted number range of the
24-digit QCOUNT counter in the LUW management table - which is of no practical
importance, however - or the restrictions regarding the volume and number of
records in a database table).
When estimating "smooth" limits, both the number of LUWs is important
and the average data volume per LUW. As a rule, we recommend to bundle data
(usually documents) already when writing to the DeltaQueue to keep number of
LUWs small (partly this can be set in the applications, e.g. in the Logistics
Cockpit). The data volume of a single LUW should not be considerably larger
than 10% of the memory available to the work process for data extraction
(in a 32-bit architecture with a memory volume of about 1GByte per work
process, 100 Mbytes per LUW should not be exceeded). That limit is of rather
small practical importance as well since a comparable limit already applies
when writing to the DeltaQueue. If the limit is observed, correct reading is
guaranteed in most cases.
If the number of LUWs cannot be reduced by bundling application transactions,
you should at least make sure that the data are fetched from all connected BWs
as quickly as possible. But for other, BW-specific, reasons, the frequency
should not be higher than one DeltaRequest per hour.
To avoid memory problems, a program-internal limit ensures that never more than
1 million LUWs are read and fetched from the database per DeltaRequest. If this
limit is reached within a request, the DeltaQueue must be emptied by several
successive DeltaRequests. We recommend, however, to try not to reach that limit
but trigger the fetching of data from the connected BWs already when the number
of LUWs reaches a 5-digit value.
Q) I would like to display the date the data was uploaded on the
report. Usually, we load the transactional data nightly. Is there any easy way
to include this information on the report for users? So that they know the
validity of the report.
A) If I understand your requirement correctly, you want to display the date on
which data was loaded into the data target from which the report is being
executed. If it is so, configure your workbook to display the text elements in
the report. This displays the relevance of data field, which is the date on which
the data load has taken place.
Q) Can we filter the fields at Transfer Structure?
Q) Can we load data directly into infoobject with out extraction is it
possible.
Yes. We can copy from other infoobject if it is same. We load data from PSA if
it is already in PSA.
Q) HOW MANY DAYS CAN WE KEEP THE DATA IN PSA, IF WE R SHEDULED DAILY, WEEKLY
AND MONTHLY.
a) We can set the time.
Q) HOW CAN U GET THE DATA FROM CLIENT IF U R WORKING ON OFFSHORE PROJECTS.
THROUGH WHICH NETWORK.
a) VPN…………….Virtual
Private Network, VPN is nothing but one sort of network
where we can connect to the client systems sitting in offshore through RAS
(Remote access server).
Q) HOW CAN U ANALIZE THE PROJECT AT FIRST?
Prepare Project Plan and Environment
Define Project Management
Standards and
Procedures
Define Implementation Standards and Procedures
Testing & Go-live + supporting.
Q) THERE is one ODS AND 4 INFOCUBES. WE SEND DATA AT TIME TO ALL CUBES IF ONE
CUBE GOT LOCK ERROR. HOW CAN U RECTIFY THE ERROR?
Go to TCode sm66 then see which one is locked select that pid from there and
goto sm12
TCode then unlock it this is happened when lock errors are occurred when u
scheduled.
Q) Can anybody tell me how to add a navigational attribute in the BEx report in
the rows?
A) Expand dimension under left side panel (that is infocube panel) select than
navigational attributes drag and drop under rows panel.
Q) IF ANY TRASACTION CODE LIKE SMPT OR STMT.
In current systems (BW 3.0B and R/3 4.6B) these Tcodes don't exist!
Q) WHAT IS TRANSACTIONAL CUBE?
A) Transactional InfoCubes differ from standard InfoCubes in that the former
have an improved write access performance level. Standard InfoCubes are
technically optimized for read-only access and for a comparatively small number
of simultaneous accesses. Instead, the transactional InfoCube was developed to
meet the demands of SAP Strategic Enterprise Management (SEM), meaning that,
data is written to the InfoCube (possibly by several users at the same time)
and re-read as soon as possible. Standard Basic cubes are not suitable for
this.
Q) Is there any way to delete cube contents within update rules from an ODS
data source? The reason for this would be to delete (or zero out) a cube record
in an "Open Order" cube if the open order quantity was 0.
I've tried using the 0recordmode but that doesn't work. Also, would it
be easier to write a program that would be run after the load and delete
the records with a zero open qty?
A) START routine for update rules u can write ABAP code.
A) Yap, you can do it. Create a start routine in Update rule.
It is not "Deleting cube contents with update rules" It is only
possible to avoid that some content is updated into the InfoCube using the
start routine. Loop at all the records and delete the record that has the
condition. "If the open order quantity was 0" You have to think also
in before and after images in case of a delta upload. In that case you may
delete the change record and keep the old and after the change the wrong
information.
Q) I am not able to access a node in hierarchy directly using variables for
reports. When I am using Tcode RSZV it is giving a message that it doesn't
exist in BW 3.0 and it is embedded in BEx. Can any one tell me the other
options to get the same functionality in BEx?
A) Tcode RSZV is used in the earlier version of 3.0B only. From 3.0B onwards,
it's possible in the Query Designer (BEx) itself. Just right click on the
InfoObject for which you want to use as variables and precede further selecting
variable type and proce -
Useful Interview Questions and Answere
Hi All
Some of the Real time question.
Q) Under which menu path is the Test Workbench to be found, including in earlier Releases?
The menu path is: Tools - ABAP Workbench - Test - Test Workbench.
Q) I want to delete a BEx query that is in Production system through request. Is anyone aware about it?
A) Have you tried the RSZDELETE transaction?
Q) Errors while monitoring process chains.
A) During data loading. Apart from them, in process chains you add so many process types, for example after loading data into Info Cube, you rollup data into aggregates, now this rolling up of data into aggregates is a process type which you keep after the process type for loading data into Cube. This rolling up into aggregates might fail.
Another one is after you load data into ODS, you activate ODS data (another process type) this might also fail.
Q) In Monitor----- Details (Header/Status/Details) à Under Processing (data packet): Everything OK à Context menu of Data Package 1 (1 Records): Everything OK -
Simulate update. (Here we can debug update rules or transfer rules.)
SM50 à Program/Mode à Program à Debugging & debug this work process.
Q) PSA Cleansing.
A) You know how to edit PSA. I don't think you can delete single records. You have to delete entire PSA data for a request.
Q) Can we make a datasource to support delta.
A) If this is a custom (user-defined) datasource you can make the datasource delta enabled. While creating datasource from RSO2, after entering datasource name and pressing create, in the next screen there is one button at the top, which says generic delta. If you want more details about this there is a chapter in Extraction book, it's in last pages u find out.
Generic delta services: -
Supports delta extraction for generic extractors according to:
Time stamp
Calendar day
Numeric pointer, such as document number & counter
Only one of these attributes can be set as a delta attribute.
Delta extraction is supported for all generic extractors, such as tables/views, SAP Query and function modules
The delta queue (RSA7) allows you to monitor the current status of the delta attribute
Q) Workbooks, as a general rule, should be transported with the role.
Here are a couple of scenarios:
1. If both the workbook and its role have been previously transported, then the role does not need to be part of the transport.
2. If the role exists in both dev and the target system but the workbook has never been transported, and then you have a choice of transporting the role (recommended) or just the workbook. If only the workbook is transported, then an additional step will have to be taken after import: Locate the WorkbookID via Table RSRWBINDEXT (in Dev and verify the same exists in the target system) and proceed to manually add it to the role in the target system via Transaction Code PFCG -- ALWAYS use control c/control v copy/paste for manually adding!
3. If the role does not exist in the target system you should transport both the role and workbook. Keep in mind that a workbook is an object unto itself and has no dependencies on other objects. Thus, you do not receive an error message from the transport of 'just a workbook' -- even though it may not be visible, it will exist (verified via Table RSRWBINDEXT).
Overall, as a general rule, you should transport roles with workbooks.
Q) How much time does it take to extract 1 million (10 lackhs) of records into an infocube?
A. This depends, if you have complex coding in update rules it will take longer time, or else it will take less than 30 minutes.
Q) What are the five ASAP Methodologies?
A: Project plan, Business Blue print, Realization, Final preparation & Go-Live - support.
1. Project Preparation: In this phase, decision makers define clear project objectives and an efficient decision making process (i.e. Discussions with the client, like what are his needs and requirements etc.). Project managers will be involved in this phase (I guess).
A Project Charter is issued and an implementation strategy is outlined in this phase.
2. Business Blueprint: It is a detailed documentation of your company's requirements. (i.e. what are the objects we need to develop are modified depending on the client's requirements).
3. Realization: In this only, the implementation of the project takes place (development of objects etc) and we are involved in the project from here only.
4. Final Preparation: Final preparation before going live i.e. testing, conducting pre-go-live, end user training etc.
End user training is given that is in the client site you train them how to work with the new environment, as they are new to the technology.
5. Go-Live & support: The project has gone live and it is into production. The Project team will be supporting the end users.
Q) What is landscape of R/3 & what is landscape of BW. Landscape of R/3 not sure.
Then Landscape of b/w: u have the development system, testing system, production system
Development system: All the implementation part is done in this sys. (I.e., Analysis of objects developing, modification etc) and from here the objects are transported to the testing system, but before transporting an initial test known as Unit testing (testing of objects) is done in the development sys.
Testing/Quality system: quality check is done in this system and integration testing is done.
Production system: All the extraction part takes place in this sys.
Q) How do you measure the size of infocube?
A: In no of records.
Q). Difference between infocube and ODS?
A: Infocube is structured as star schema (extended) where a fact table is surrounded by different dim table that are linked with DIM'ids. And the data wise, you will have aggregated data in the cubes. No overwrite functionality
ODS is a flat structure (flat table) with no star schema concept and which will have granular data (detailed level). Overwrite functionality.
Flat file datasources does not support 0recordmode in extraction.
x before, -after, n new, a add, d delete, r reverse
Q) Difference between display attributes and navigational attributes?
A: Display attribute is one, which is used only for display purpose in the report. Where as navigational attribute is used for drilling down in the report. We don't need to maintain Navigational attribute in the cube as a characteristic (that is the advantage) to drill down.
Q. SOME DATA IS UPLOADED TWICE INTO INFOCUBE. HOW TO CORRECT IT?
A: But how is it possible? If you load it manually twice, then you can delete it by requestID.
Q. CAN U ADD A NEW FIELD AT THE ODS LEVEL?
Sure you can. ODS is nothing but a table.
Q. CAN NUMBER OF DATASOURCES HAVE ONE INFOSOURCE?
A) Yes of course. For example, for loading text and hierarchies we use different data sources but the same InfoSource.
Q. BRIEF THE DATAFLOW IN BW.
A) Data flows from transactional system to analytical system (BW). DataSources on the transactional system needs to be replicated on BW side and attached to infosource and update rules respectively.
Q. CURRENCY CONVERSIONS CAN BE WRITTEN IN UPDATE RULES. WHY NOT IN TRANSFER RULES?
Q) WHAT IS PROCEDURE TO UPDATE DATA INTO DATA TARGETS?
FULL and DELTA.
Q) AS WE USE Sbwnn, sbiw1, sbiw2 for delta update in LIS THEN WHAT IS THE PROCEDURE IN LO-COCKPIT?
No LIS in LO cockpit. We will have datasources and can be maintained (append fields). Refer white paper on LO-Cockpit extractions.
Q) Why we delete the setup tables (LBWG) & fill them (OLI*BW)?
A) Initially we don't delete the setup tables but when we do change in extract structure we go for it. We r changing the extract structure right, that means there are some newly added fields in that which r not before. So to get the required data (i.e.; the data which is required is taken and to avoid redundancy) we delete n then fill the setup tables.
To refresh the statistical data. The extraction set up reads the dataset that you want to process such as, customers orders with the tables like VBAK, VBAP) & fills the relevant communication structure with the data. The data is stored in cluster tables from where it is read when the initialization is run. It is important that during initialization phase, no one generates or modifies application data, at least until the tables can be set up.
Q) SIGNIFICANCE of ODS?
It holds granular data (detailed level).
Q) WHERE THE PSA DATA IS STORED?
In PSA table.
Q) WHAT IS DATA SIZE?
The volume of data one data target holds (in no. of records)
Q) Different types of INFOCUBES.
Basic, Virtual (remote, sap remote and multi)
Virtual Cube is used for example, if you consider railways reservation all the information has to be updated online. For designing the Virtual cube you have to write the function module that is linking to table, Virtual cube it is like a the structure, when ever the table is updated the virtual cube will fetch the data from table and display report Online... FYI.. you will get the information : https://www.sdn.sap.com/sdn/index.sdn and search for Designing Virtual Cube and you will get a good material designing the Function Module
Q) INFOSET QUERY.
Can be made of ODS's and Characteristic InfoObjects with masterdata.
Q) IF THERE ARE 2 DATASOURCES HOW MANY TRANSFER STRUCTURES ARE THERE.
In R/3 or in BW? 2 in R/3 and 2 in BW
Q) ROUTINES?
Exist in the InfoObject, transfer routines, update routines and start routine
Q) BRIEF SOME STRUCTURES USED IN BEX.
Rows and Columns, you can create structures.
Q) WHAT ARE THE DIFFERENT VARIABLES USED IN BEX?
Different Variable's are Texts, Formulas, Hierarchies, Hierarchy nodes & Characteristic values.
Variable Types are
Manual entry /default value
Replacement path
SAP exit
Customer exit
Authorization

Q) What types of partitioning are there for BW?
There are two Partitioning Performance aspects for BW (Cube & PSA)
Query Data Retrieval Performance Improvement:
Partitioning by (say) Date Range improves data retrieval by making best use of database execution plans and indexes (of say Oracle database engine).
B) Transactional Load Partitioning Improvement:
Partitioning based on expected load volumes and data element sizes. Improves data loading into PSA and Cubes by infopackages (Eg. without timeouts).
Q) How can I compare data in R/3 with data in a BW Cube after the daily delta loads? Are there any standard procedures for checking them or matching the number of records?
A) You can go to R/3 TCode RSA3 and run the extractor. It will give you the number of records extracted. Then go to BW Monitor to check the number of records in the PSA and check to see if it is the same & also in the monitor header tab.
A) RSA3 is a simple extractor checker program that allows you to rule out extracts problems in R/3. It is simple to use, but only really tells you if the extractor works. Since records that get updated into Cubes/ODS structures are controlled by Update Rules, you will not be able to determine what is in the Cube compared to what is in the R/3 environment. You will need to compare records on a 1:1 basis against records in R/3 transactions for the functional area in question. I would recommend enlisting the help of the end user community to assist since they presumably know the data.
To use RSA3, go to it and enter the extractor ex: 2LIS_02_HDR. Click execute and you will see the record count, you can also go to display that data. You are not modifying anything so what you do in RSA3 has no effect on data quality afterwards. However, it will not tell you how many records should be expected in BW for a given load. You have that information in the monitor RSMO during and after data loads. From RSMO for a given load you can determine how many records were passed through the transfer rules from R/3, how many targets were updated, and how many records passed through the Update Rules. It also gives you error messages from the PSA.
Q) Types of Transfer Rules?
A) Field to Field mapping, Constant, Variable & routine.
Q) Types of Update Rules?
A) (Check box), Return table
Q) Transfer Routine?
A) Routines, which we write in, transfer rules.
Q) Update Routine?
A) Routines, which we write in Update rules
Q) What is the difference between writing a routine in transfer rules and writing a routine in update rules?
A) If you are using the same InfoSource to update data in more than one data target its better u write in transfer rules because u can assign one InfoSource to more than one data target & and what ever logic u write in update rules it is specific to particular one data target.
Q) Routine with Return Table.
A) Update rules generally only have one return value. However, you can create a routine in the tab strip key figure calculation, by choosing checkbox Return table. The corresponding key figure routine then no longer has a return value, but a return table. You can then generate as many key figure values, as you like from one data record.
Q) Start routines?
A) Start routines u can write in both updates rules and transfer rules, suppose you want to restrict (delete) some records based on conditions before getting loaded into data targets, then you can specify this in update rules-start routine.
Ex: - Delete Data_Package ani ante it will delete a record based on the condition
Q) X & Y Tables?
X-table = A table to link material SIDs with SIDs for time-independent navigation attributes.
Y-table = A table to link material SIDs with SIDS for time-dependent navigation attributes.
There are four types of sid tables
X time independent navigational attributes sid tables
Y time dependent navigational attributes sid tables
H hierarchy sid tables
I hierarchy structure sid tables
Q) Filters & Restricted Key figures (real time example)
Restricted KF's u can have for an SD cube: billed quantity, billing value, no: of billing documents as RKF's.
Q) Line-Item Dimension (give me an real time example)
Line-Item Dimension: Invoice no: or Doc no: is a real time example
Q) What does the number in the 'Total' column in Transaction RSA7 mean?
A) The 'Total' column displays the number of LUWs that were written in the delta queue and that have not yet been confirmed. The number includes the LUWs of the last delta request (for repetition of a delta request) and the LUWs for the next delta request. A LUW only disappears from the RSA7 display when it has been transferred to the BW System and a new delta request has been received from the BW System.
Q) How to know in which table (SAP BW) contains Technical Name / Description and creation data of a particular Reports. Reports that are created using BEx Analyzer.
A) There is no such table in BW if you want to know such details while you are opening a particular query press properties button you will come to know all the details that you wanted.
You will find your information about technical names and description about queries in the following tables. Directory of all reports (Table RSRREPDIR) and Directory of the reporting component elements (Table RSZELTDIR) for workbooks and the connections to queries check Where- used list for reports in workbooks (Table RSRWORKBOOK) Titles of Excel Workbooks in InfoCatalog (Table RSRWBINDEXT)
Q) What is a LUW in the delta queue?
A) A LUW from the point of view of the delta queue can be an individual document, a group of documents from a collective run or a whole data packet of an application extractor.
Q) Why does the number in the 'Total' column in the overview screen of Transaction RSA7 differ from the number of data records that is displayed when you call the detail view?
A) The number on the overview screen corresponds to the total of LUWs (see also first question) that were written to the qRFC queue and that have not yet been confirmed. The detail screen displays the records contained in the LUWs. Both, the records belonging to the previous delta request and the records that do not meet the selection conditions of the preceding delta init requests are filtered out. Thus, only the records that are ready for the next delta request are displayed on the detail screen. In the detail screen of Transaction RSA7, a possibly existing customer exit is not taken into account.
Q) Why does Transaction RSA7 still display LUWs on the overview screen after successful delta loading?
A) Only when a new delta has been requested does the source system learn that the previous delta was successfully loaded to the BW System. Then, the LUWs of the previous delta may be confirmed (and also deleted). In the meantime, the LUWs must be kept for a possible delta request repetition. In particular, the number on the overview screen does not change when the first delta was loaded to the BW System.
Q) Why are selections not taken into account when the delta queue is filled?
A) Filtering according to selections takes place when the system reads from the delta queue. This is necessary for reasons of performance.
Q) Why is there a DataSource with '0' records in RSA7 if delta exists and has also been loaded successfully?
It is most likely that this is a DataSource that does not send delta data to the BW System via the delta queue but directly via the extractor (delta for master data using ALE change pointers). Such a DataSource should not be displayed in RSA7. This error is corrected with BW 2.0B Support Package 11.
Q) Do the entries in table ROIDOCPRMS have an impact on the performance of the loading procedure from the delta queue?
A) The impact is limited. If performance problems are related to the loading process from the delta queue, then refer to the application-specific notes (for example in the CO-PA area, in the logistics cockpit area and so on).
Caution: As of Plug In 2000.2 patch 3 the entries in table ROIDOCPRMS are as effective for the delta queue as for a full update. Please note, however, that LUWs are not split during data loading for consistency reasons. This means that when very large LUWs are written to the DeltaQueue, the actual package size may differ considerably from the MAXSIZE and MAXLINES parameters.
Q) Why does it take so long to display the data in the delta queue (for example approximately 2 hours)?
A) With Plug In 2001.1 the display was changed: the user has the option of defining the amount of data to be displayed, to restrict it, to selectively choose the number of a data record, to make a distinction between the 'actual' delta data and the data intended for repetition and so on.
Q) What is the purpose of function 'Delete data and meta data in a queue' in RSA7? What exactly is deleted?
A) You should act with extreme caution when you use the deletion function in the delta queue. It is comparable to deleting an InitDelta in the BW System and should preferably be executed there. You do not only delete all data of this DataSource for the affected BW System, but also lose the entire information concerning the delta initialization. Then you can only request new deltas after another delta initialization.
When you delete the data, the LUWs kept in the qRFC queue for the corresponding target system are confirmed. Physical deletion only takes place in the qRFC outbound queue if there are no more references to the LUWs.
The deletion function is for example intended for a case where the BW System, from which the delta initialization was originally executed, no longer exists or can no longer be accessed.
Q) Why does it take so long to delete from the delta queue (for example half a day)?
A) Import PlugIn 2000.2 patch 3. With this patch the performance during deletion is considerably improved.
Q) Why is the delta queue not updated when you start the V3 update in the logistics cockpit area?
A) It is most likely that a delta initialization had not yet run or that the delta initialization was not successful. A successful delta initialization (the corresponding request must have QM status 'green' in the BW System) is a prerequisite for the application data being written in the delta queue.
Q) What is the relationship between RSA7 and the qRFC monitor (Transaction SMQ1)?
A) The qRFC monitor basically displays the same data as RSA7. The internal queue name must be used for selection on the initial screen of the qRFC monitor. This is made up of the prefix 'BW, the client and the short name of the DataSource. For DataSources whose name are 19 characters long or shorter, the short name corresponds to the name of the DataSource. For DataSources whose name is longer than 19 characters (for delta-capable DataSources only possible as of PlugIn 2001.1) the short name is assigned in table ROOSSHORTN.
In the qRFC monitor you cannot distinguish between repeatable and new LUWs. Moreover, the data of a LUW is displayed in an unstructured manner there.
Q) Why are the data in the delta queue although the V3 update was not started?
A) Data was posted in background. Then, the records are updated directly in the delta queue (RSA7). This happens in particular during automatic goods receipt posting (MRRS). There is no duplicate transfer of records to the BW system. See Note 417189.
Q) Why does button 'Repeatable' on the RSA7 data details screen not only show data loaded into BW during the last delta but also data that were newly added, i.e. 'pure' delta records?
A) Was programmed in a way that the request in repeat mode fetches both actually repeatable (old) data and new data from the source system.
Q) I loaded several delta inits with various selections. For which one is the delta loaded?
A) For delta, all selections made via delta inits are summed up. This means, a delta for the 'total' of all delta initializations is loaded.
Q) How many selections for delta inits are possible in the system?
A) With simple selections (intervals without complicated join conditions or single values), you can make up to about 100 delta inits. It should not be more.
With complicated selection conditions, it should be only up to 10-20 delta inits.
Reason: With many selection conditions that are joined in a complicated way, too many 'where' lines are generated in the generated ABAP source code that may exceed the memory limit.
Q) I intend to copy the source system, i.e. make a client copy. What will happen with may delta? Should I initialize again after that?
A) Before you copy a source client or source system, make sure that your deltas have been fetched from the DeltaQueue into BW and that no delta is pending. After the client copy, an inconsistency might occur between BW delta tables and the OLTP delta tables as described in Note 405943. After the client copy, Table ROOSPRMSC will probably be empty in the OLTP since this table is client-independent. After the system copy, the table will contain the entries with the old logical system name that are no longer useful for further delta loading from the new logical system. The delta must be initialized in any case since delta depends on both the BW system and the source system. Even if no dump 'MESSAGE_TYPE_X' occurs in BW when editing or creating an InfoPackage, you should expect that the delta have to be initialized after the copy.
Q) Is it allowed in Transaction SMQ1 to use the functions for manual control of processes?
A) Use SMQ1 as an instrument for diagnosis and control only. Make changes to BW queues only after informing the BW Support or only if this is explicitly requested in a note for component 'BC-BW' or 'BW-WHM-SAPI'.
Q) Despite of the delta request being started after completion of the collective run (V3 update), it does not contain all documents. Only another delta request loads the missing documents into BW. What is the cause for this "splitting"?
A) The collective run submits the open V2 documents for processing to the task handler, which processes them in one or several parallel update processes in an asynchronous way. For this reason, plan a sufficiently large "safety time window" between the end of the collective run in the source system and the start of the delta request in BW. An alternative solution where this problem does not occur is described in Note 505700.
Q) Despite my deleting the delta init, LUWs are still written into the DeltaQueue?
A) In general, delta initializations and deletions of delta inits should always be carried out at a time when no posting takes place. Otherwise, buffer problems may occur: If a user started the internal mode at a time when the delta initialization was still active, he/she posts data into the queue even though the initialization had been deleted in the meantime. This is the case in your system.
Q) In SMQ1 (qRFC Monitor) I have status 'NOSEND'. In the table TRFCQOUT, some entries have the status 'READY', others 'RECORDED'. ARFCSSTATE is 'READ'. What do these statuses mean? Which values in the field 'Status' mean what and which values are correct and which are alarming? Are the statuses BW-specific or generally valid in qRFC?
A) Table TRFCQOUT and ARFCSSTATE: Status READ means that the record was read once either in a delta request or in a repetition of the delta request. However, this does not mean that the record has successfully reached the BW yet. The status READY in the TRFCQOUT and RECORDED in the ARFCSSTATE means that the record has been written into the DeltaQueue and will be loaded into the BW with the next delta request or a repetition of a delta. In any case only the statuses READ, READY and RECORDED in both tables are considered to be valid. The status EXECUTED in TRFCQOUT can occur temporarily. It is set before starting a DeltaExtraction for all records with status READ present at that time. The records with status EXECUTED are usually deleted from the queue in packages within a delta request directly after setting the status before extracting a new delta. If you see such records, it means that either a process which is confirming and deleting records which have been loaded into the BW is successfully running at the moment, or, if the records remain in the table for a longer period of time with status EXECUTED, it is likely that there are problems with deleting the records which have already been successfully been loaded into the BW. In this state, no more deltas are loaded into the BW. Every other status is an indicator for an error or an inconsistency. NOSEND in SMQ1 means nothing (see note 378903).
The value 'U' in field 'NOSEND' of table TRFCQOUT is discomforting.
Q) The extract structure was changed when the DeltaQueue was empty. Afterwards new delta records were written to the DeltaQueue. When loading the delta into the PSA, it shows that some fields were moved. The same result occurs when the contents of the DeltaQueue are listed via the detail display. Why are the data displayed differently? What can be done?
Make sure that the change of the extract structure is also reflected in the database and that all servers are synchronized. We recommend to reset the buffers using Transaction $SYNC. If the extract structure change is not communicated synchronously to the server where delta records are being created, the records are written with the old structure until the new structure has been generated. This may have disastrous consequences for the delta.
When the problem occurs, the delta needs to be re-initialized.
Q) How and where can I control whether a repeat delta is requested?
A) Via the status of the last delta in the BW Request Monitor. If the request is RED, the next load will be of type 'Repeat'. If you need to repeat the last load for certain reasons, set the request in the monitor to red manually. For the contents of the repeat see Question 14. Delta requests set to red despite of data being already updated lead to duplicate records in a subsequent repeat, if they have not been deleted from the data targets concerned before.
Q) As of PI 2003.1, the Logistic Cockpit offers various types of update methods. Which update method is recommended in logistics? According to which criteria should the decision be made? How can I choose an update method in logistics?
See the recommendation in Note 505700.
Q) Are there particular recommendations regarding the data volume the DeltaQueue may grow to without facing the danger of a read failure due to memory problems?
A) There is no strict limit (except for the restricted number range of the 24-digit QCOUNT counter in the LUW management table - which is of no practical importance, however - or the restrictions regarding the volume and number of records in a database table).
When estimating "smooth" limits, both the number of LUWs is important and the average data volume per LUW. As a rule, we recommend to bundle data (usually documents) already when writing to the DeltaQueue to keep number of LUWs small (partly this can be set in the applications, e.g. in the Logistics Cockpit). The data volume of a single LUW should not be considerably larger than 10% of the memory available to the work process for data extraction (in a 32-bit architecture with a memory volume of about 1GByte per work process, 100 Mbytes per LUW should not be exceeded). That limit is of rather small practical importance as well since a comparable limit already applies when writing to the DeltaQueue. If the limit is observed, correct reading is guaranteed in most cases.
If the number of LUWs cannot be reduced by bundling application transactions, you should at least make sure that the data are fetched from all connected BWs as quickly as possible. But for other, BW-specific, reasons, the frequency should not be higher than one DeltaRequest per hour.
To avoid memory problems, a program-internal limit ensures that never more than 1 million LUWs are read and fetched from the database per DeltaRequest. If this limit is reached within a request, the DeltaQueue must be emptied by several successive DeltaRequests. We recommend, however, to try not to reach that limit but trigger the fetching of data from the connected BWs already when the number of LUWs reaches a 5-digit value.
Q) I would like to display the date the data was uploaded on the report. Usually, we load the transactional data nightly. Is there any easy way to include this information on the report for users? So that they know the validity of the report.
A) If I understand your requirement correctly, you want to display the date on which data was loaded into the data target from which the report is being executed. If it is so, configure your workbook to display the text elements in the report. This displays the relevance of data field, which is the date on which the data load has taken place.
Q) Can we filter the fields at Transfer Structure?
Q) Can we load data directly into infoobject with out extraction is it possible.
Yes. We can copy from other infoobject if it is same. We load data from PSA if it is already in PSA.
Q) HOW MANY DAYS CAN WE KEEP THE DATA IN PSA, IF WE R SHEDULED DAILY, WEEKLY AND MONTHLY.
a) We can set the time.
Q) HOW CAN U GET THE DATA FROM CLIENT IF U R WORKING ON OFFSHORE PROJECTS. THROUGH WHICH NETWORK.
a) VPN .Virtual Private Network, VPN is nothing but one sort of network where we can connect to the client systems sitting in offshore through RAS (Remote access server).
Q) HOW CAN U ANALIZE THE PROJECT AT FIRST?
Prepare Project Plan and Environment
Define Project Management Standards and
Procedures
Define Implementation Standards and Procedures
Testing & Go-live + supporting.
Q) THERE is one ODS AND 4 INFOCUBES. WE SEND DATA AT TIME TO ALL CUBES IF ONE CUBE GOT LOCK ERROR. HOW CAN U RECTIFY THE ERROR?
Go to TCode sm66 then see which one is locked select that pid from there and goto sm12
TCode then unlock it this is happened when lock errors are occurred when u scheduled.
Q) Can anybody tell me how to add a navigational attribute in the BEx report in the rows?
A) Expand dimension under left side panel (that is infocube panel) select than navigational attributes drag and drop under rows panel.
Q) IF ANY TRASACTION CODE LIKE SMPT OR STMT.
In current systems (BW 3.0B and R/3 4.6B) these Tcodes don't exist!
Q) WHAT IS TRANSACTIONAL CUBE?
A) Transactional InfoCubes differ from standard InfoCubes in that the former have an improved write access performance level. Standard InfoCubes are technically optimized for read-only access and for a comparatively small number of simultaneous accesses. Instead, the transactional InfoCube was developed to meet the demands of SAP Strategic Enterprise Management (SEM), meaning that, data is written to the InfoCube (possibly by several users at the same time) and re-read as soon as possible. Standard Basic cubes are not suitable for this.
Q) Is there any way to delete cube contents within update rules from an ODS data source? The reason for this would be to delete (or zero out) a cube record in an "Open Order" cube if the open order quantity was 0.
I've tried using the 0recordmode but that doesn't work. Also, would it
be easier to write a program that would be run after the load and delete
the records with a zero open qty?
A) START routine for update rules u can write ABAP code.
A) Yap, you can do it. Create a start routine in Update rule.
It is not "Deleting cube contents with update rules" It is only possible to avoid that some content is updated into the InfoCube using the start routine. Loop at all the records and delete the record that has the condition. "If the open order quantity was 0" You have to think also in before and after images in case of a delta upload. In that case you may delete the change record and keep the old and after the change the wrong information.
Q) I am not able to access a node in hierarchy directly using variables for reports. When I am using Tcode RSZV it is giving a message that it doesn't exist in BW 3.0 and it is embedded in BEx. Can any one tell me the other options to get the same functionality in BEx?
A) Tcode RSZV is used in the earlier version of 3.0B only. From 3.0B onwards, it's possible in the Query Designer (BEx) itself. Just right click on the InfoObject for which you want to use as variables and precede further selecting variable type and processing types.
Q) Wondering how can I get the values, for an example, if I run a report for month range 01/2004 - 10/2004 then monthly value is actually divide by the number of months that I selected. Which variable should I use?
Q) Why is it every time I switch from Info Provider to InfoObject or from one item to another while in modeling I always get this message " Reading Data " or "constructing workbench" in it runs for minutes.... anyway to stop this?
Q) Can any one give me info on how the BW delta works also would like to know about 'before image and after image' am currently in a BW project and have to write start routines for delta load.
Q) I am very new to BW. I would like to clarify a doubt regarding Delta extractor. If I am correct, by using delta extractors the data that has already been scheduled will not be uploaded again. Say for a specific scenario, Sales. Now I have uploaded all the sales order created till yesterday into the cube. Now say I make changes to any of the open record, which was already uploaded. Now what happens when I schedule it again? Will the same record be uploaded again with the changes or will the changes get affected to the previous record.
A)
Q) In BW we need to write abap routines. I wish to know when and what type of abap routines we got to write. Also, are these routines written in update rules? I will be glad, if this is clarified with real-time scenarios and few examples?
A) Over here we write our routines in the start routines in the update rules or in the transfer structure (you can choose between writing them in the start routines or directly behind the different characteristics. In the transfer structure you just click on the yellow triangle behind a characteristic and choose "routine". In the update rules you can choose "start routine" or click on the triangle with the green square behind an individual characteristic. Usually we only use start routine when it does not concern one single characteristic (for example when you have to read the same table for 4 characteristics). I hope this helps.
We used ABAP Routines for example:
To convert to Uppercase (transfer structure)
To convert Values out of a third party tool with different keys into the same keys as our SAP System uses (transfer structure)
To select only a part of the data for from an infosource updating the InfoCube (Start Routine) etc.
Q) What is ODS?
A) An ODS object acts as a storage location for consolidated and cleaned-up transaction data (transaction data or master data, for example) on the document (atomic) level.
This data can be evaluated using a BEx query.
Standard ODS Object
Transactional ODS object:
The data is immediately available here for reporting. For implementation, compare with the Transactional ODS Object.
A transactional ODS object differs from a standard ODS object in the way it prepares data. In a standard ODS object, data is stored in different versions ((new) delta, active, (change log) modified), where as a transactional ODS object contains the data in a single version. Therefore, data is stored in precisely the same form in which it was written to the transactional ODS object by the application. In BW, you can use a transaction ODS object as a data target for an analysis process.
The transactional ODS object is also required by diverse applications, such as SAP Strategic Enterprise Management (SEM) for example, as well as other external applications.
Transactional ODS objects allow data to be available quickly. The data from this kind of ODS object is accessed transactionally, that is, data is written to the ODS object (possibly by several users at the same time) and reread as soon as possible.
It offers no replacement for the standard ODS object. Instead, an additional function displays those that can be used for special applications.
The transactional ODS object simply consists of a table for active data. It retrieves its data from external systems via fill- or delete- APIs. The loading process is not supported by the BW system. The advantage to the way it is structured is that data is easy to access. They are made available for reporting immediately after being loaded.
Q) What does InfoCube contains?
A) Each InfoCube has one FactTable & a maximum of 16 (13+3 system defined, time, unit & data packet) dimensions.
Q) What does FACT Table contain?
A FactTable consists of KeyFigures.
Each Fact Table can contain a maximum of 233 key figures.
Dimension can contain up to 248 freely available characteristics.
Q) How many dimensions are in a CUBE?
A) 16 dimensions. (13 user defined & 3 system pre-defined )
Q) What does SID Table contain?
SID keys linked with dimension table & master data tables (attributes, texts, hierarchies)
Q) What does ATTRIBUTE Table contain?
Master attribute data
Q) What does TEXT Table contain?
Master text data, short text, long text, medium text & language key if it is language dependent
Q) What does Hierarchy table contain?Hi DST
This is a great effort and gesture. thank you on behalf of all the newbies.

Hello Experts. I am asking this question again as I didn't get any answers last time.
I am creating a report that will have Open Orders, Sales Orders and Deliveries.
For my open orders, I want to see:
1.sales orders or the deliveries, which are not billed
2.deliveries which are not goods issued
3.sales order which are confirmed, but not delivered
4. Or any other type of open order.
I need to know what are the Data Sources in LO Cockpit that I need to activate?
These data sources will be feeding the cube 0SD_C03.
According to my research, I hace listed the following datasources:
2LIS_11VAHDR
2LIS_11_VAITM
<u>2LIS_11_V_ITM</u>
2LIS_11_V_SCL
<u>2LIS_11_V_SSL</u>
2LIS_12_VAHDR
2LIS_12_VCITM
<u>2LIS_12_VCSCL</u>
2LIS_13_VDITM
2LIS_13_VDHDR
I am having serios doubts about using the underlined datasources.
Any help will be greatly appreciated.
Thanks.
JanetHi...From my own experience i recommend you to activate the possible datasources that you think could be useful for you...and run the RSA3 transaction in order to see if any of them beings the data you need....
check the Help.sap.com in order to see tha structure for every datsource

Questions on Direct and Indirect??
Hi Experts,
My questions are
a) What is direct procurement and what will be the process in CS and ECS?
b) What is the difference with Plan-Driven procurement and Direct procurement?
c) and When we order one material what will be the further process (Follow-o Documents,and Any SAP-MM) key points??
Please help me in this regard.Hi
Please follow answers
a) What is direct procurement and what will be the process in CS and ECS?
Ans -
Direct procurment mean procument if direct material (production material)
b) What is the difference with Plan-Driven procurement and Direct procurement?
Ans - both the things are differant
direct procurement is normal procument cycle .. SC - PO - GR IV ..
after SC other doc can be created in back end depending upon the senario.
Plan driven procument is degined to get requirements from other back end system in sourcing cockpit directly, they does not require any approval flow in SRM as that of normal approch.

muraliHi
I have few questions and answer u can check it out which would be more helpful
Solution
Questions and answers.
Question 1:
What does the number in the 'Total' column in Transaction RSA7 mean?
Answer:
The 'Total' column displays the number of LUWs that were written in the delta queue and that have not yet been confirmed. The number includes the LUWs of the last delta request (for repeating a delta request) and the LUWs for the next delta request. An LUW only disappears from the RSA7 display when it has been transferred to the BW System and a new delta request has been received from the BW System.
Question 2:
What is an LUW in the delta queue?
Answer:
An LUW from the point of view of the delta queue can be an individual document, a group of documents from a collective run or a whole data packet from an application extractor.
Question 3:
Why does the number in the 'Total' column, in the overview screen of Transaction RSA7, differ from the number of data records that are displayed when you call up the detail view?
Answer:
The number on the overview screen corresponds to the total number of LUWs (see also question 1) that were written to the qRFC queue and that have not yet been confirmed. The detail screen displays the records contained in the LUWs. Both the records belonging to the previous delta request and the records that do not meet the selection conditions of the preceding delta init requests are filtered out. This means that only the records that are ready for the next delta request are displayed on the detail screen. The detail screen of Transaction RSA7 does not take into account a possibly existing customer exit.
Question 4:
Why does Transaction RSA7 still display LUWs on the overview screen after successful delta loading?
Answer:
Only when a new delta has been requested does the source system learn that the previous delta was successfully loaded into the BW System. The LUWs of the previous delta may then be confirmed (and also deleted). In the meantime, the LUWs must be kept for a possible delta request repetition. In particular, the number on the overview screen does not change if the first delta is loaded into the BW System.
Question 5:
Why are selections not taken into account when the delta queue is filled?
Answer:
Filtering according to selections takes place when the system reads from the delta queue. This is necessary for performance reasons.
Question 6:
Why is there a DataSource with '0' records in RSA7 if delta exists and has been loaded successfully?
Answer:
It is most likely that this is a DataSource that does not send delta data to the BW System via the delta queue but directly via the extractor . You can display the current delta data for these DataSources using TA RSA3 (update mode ='D')
Question 7:
Do the entries in Table ROIDOCPRMS have an impact on the performance of the loading procedure from the delta queue?
Answer:
The impact is limited. If performance problems are related to the loading process from the delta queue, then refer to the application-specific notes (for example in the CO-PA area, in the logistics cockpit area, and so on).
Caution: As of PlugIn 2000.2 patch 3, the entries in Table ROIDOCPRMS are as effective for the delta queue as for a full update. Note, however, that LUWs are not split during data loading for consistency reasons. This means that when very large LUWs are written to the delta queue, the actual package size may differ considerably from the MAXSIZE and MAXLINES parameters.
Question 8:
Why does it take so long to display the data in the delta queue (for example approximately 2 hours)?
Answer:
With PlugIn 2001.1 the display was changed: you are now able to define the amount of data to be displayed, to restrict it, to selectively choose the number of a data record, to make a distinction between the 'actual' delta data and the data intended for repetition, and so on.
Question 9:
What is the purpose of the function 'Delete Data and Meta Data in a Queue' in RSA7? What exactly is deleted?
Answer:
You should act with extreme caution when you use the delete function in the delta queue. It is comparable to deleting an InitDelta in the BW System and should preferably be executed there. Not only do you delete all data of this DataSource for the affected BW System, but you also lose all the information concerning the delta initialization. Then you can only request new deltas after another delta initialization.
When you delete the data, this confirms the LUWs kept in the qRFC queue for the corresponding target system. Physical deletion only takes place in the qRFC outbound queue if there are no more references to the LUWs.
The delete function is intended for example, for cases where the BW System, from which the delta initialization was originally executed, no longer exists or can no longer be accessed.
Question 10:
Why does it take so long to delete from the delta queue (for example half a day)?
Answer:
Import PlugIn 2000.2 patch 3. With this patch the performance during deletion improves considerably.
Question 11:
Why is the delta queue not updated when you start the V3 update in the logistics cockpit area?
Answer:
It is most likely that a delta initialization had not yet run or that the the delta initialization was not successful. A successful delta initialization (the corresponding request must have QM status 'green' in the BW System) is a prerequisite for the application data to be written to the delta queue.
Question 12:
What is the relationship between RSA7 and the qRFC monitor (Transaction SMQ1)?
Answer:
The qRFC monitor basically displays the same data as RSA7. The internal queue name must be used for selection on the initial screen of the qRFC monitor. This is made up of the prefix 'BW, the client and the short name of the DataSource. For DataSources whose name is shorter than 20 characters, the short name corresponds to the name of the DataSource. For DataSources whose name is longer than 19 characters (for delta-capable DataSources only possible as of PlugIn 2001.1) the short name is assigned in Table ROOSSHORTN.
In the qRFC monitor you cannot distinguish between repeatable and new LUWs. Moreover, the data of a LUW is displayed in an unstructured manner there.
Question 13:
Why is there data in the delta queue although the V3 update has not yet been started?
Answer:
You posted data in the background. This means that the records are updated directly in the delta queue (RSA7). This happens in particular during automatic goods receipt posting (MRRS). There is no duplicate transfer of records to the BW system. See Note 417189.
Question 14:
Why does the 'Repeatable' button on the RSA7 data details screen not only show data loaded into BW during the last delta but also newly-added data, in other words, 'pure' delta records?
Answer:
It was programmed so that the request in repeat mode fetches both actually repeatable (old) data and new data from the source system.
Question 15:
I loaded several delta inits with various selections. For which one
is the delta loaded?
Answer:
For delta, all selections made via delta inits are summed up. This
means a delta for the 'total' of all delta initializations is loaded.
Question 16:
How many selections for delta inits are possible in the system?
Answer:
With simple selections (intervals without complicated join conditions or single values), you can make up to about 100 delta inits. It should not be more.
With complicated selection conditions, it should be only up to 10-20 delta inits.
Reason: With many selection conditions that are joined in a complicated way, too many 'where' lines are generated in the generated ABAP source code which may exceed the memory limit.
Question 17:
I intend to copy the source system, i.e. make a client copy. What will happen with may delta? Should I initialize again after that?
Answer:
Before you copy a source client or source system, make sure that your deltas have been fetched from the delta queue into BW and that no delta is pending. After the client copy, an inconsistency might occur between BW delta tables and the OLTP delta tables as described in Note 405943. After the client copy, Table ROOSPRMSC will probably be empty in the OLTP since this table is client-independent. After the system copy, the table will contain the entries with the old logical system name which are no longer useful for further delta loading from the new logical system. The delta must be initialized in any case since delta depends on both the BW system and the source system. Even if no dump 'MESSAGE_TYPE_X' occurs in BW when editing or creating an InfoPackage, you should expect that the delta has to be initialized after the copy.
Question 18.
Am I permitted to use the functions in Transaction SMQ1 to manually control processes?
Answer:
Use SMQ1 as an instrument for diagnosis and control only. Make changes to BW queues only after informing BW Support or only if this is explicitly requested in a note for Component 'BC-BW' or 'BW-WHM-SAPI'.
Question 19.
Despite the delta request only being started after completion of the collective run (V3 update), it does not contain all documents. Only another delta request loads the missing documents into BW. What is the cause for this "splitting"?
Answer:
The collective run submits the open V2 documents to the task handler for processing. The task handler processes them in one or several parallel update processes in an asynchronous way. For this reason, plan a sufficiently large "safety time window" between the end of the collective run in the source system and the start of the delta request in BW. An alternative solution where this problem does not occur is described in Note 505700.
Question 20.
Despite deleting the delta init, LUWs are still written into the DeltaQueue
Answer:
In general, delta initializations and deletions of delta inits should always be carried out at a time when no posting takes place. Otherwise, buffer problems may occur: If you started the internal mode at a time when the delta initialization was still active, you post data into the queue even though the initialization had been deleted in the meantime. This is the case in your system.
Question 21.
In SMQ1 (qRFC Monitor) I have status 'NOSEND'. In the Table TRFCQOUT, some entries have the status 'READY', others 'RECORDED'. ARFCSSTATE is 'READ'. What do these statuses mean? Which values in the field 'Status' mean what and which values are correct and which are alarming? Are the statuses BW-specific or generally valid in qRFC?
Answer:
Table TRFCQOUT and ARFCSSTATE: Status READ means that the record was read once either in a delta request or in a repetition of the delta request. However, this still does not mean that the record has successfully reached the BW. The status READY in the TRFCQOUT and RECORDED in the ARFCSSTATE means that the record has been written into the delta queue and will be loaded into the BW with the next delta request or a repetition of a delta. In any case only the statuses READ, READY and RECORDED in both tables are considered to be valid. The status EXECUTED in TRFCQOUT can occur temporarily. It is set before starting a delta extraction for all records with status READ present at that time. The records with status EXECUTED are usually deleted from the queue in packages within a delta request directly after setting the status before extracting a new delta. If you see such records, it means that either a process which confirms and deletes records loaded into the BW is successfully running at the moment, or, if the records remain in the table for a longer period of time with status EXECUTED, it is likely that there are problems with deleting the records which have already been successfully been loaded into the BW. In this state, no more deltas are loaded into the BW. Every other status indicates an error or an inconsistency. NOSEND in SMQ1 means nothing (see note 378903). However the value 'U' in field 'NOSEND' of table TRFCQOUT is of concern.
Question 22.
The extract structure was changed when the delta queue was empty. Afterwards new delta records were written to the delta queue. When loading the delta into the PSA, it shows that some fields were moved. The same result occurs when the contents of the delta queue are listed via the detail display. Why is the data displayed differently? What can be done?
Answer:
Make sure that the change of the extract structure is also reflected in the database and that all servers are synchronized. We recommend resetting the buffers using Transaction $SYNC. If the extract structure change is not communicated synchronously to the server where delta records are being created, the records are written with the old structure until the new structure has been generated. This may have disastrous consequences for the delta. When the problem occurs, the delta needs to be re-initialized.
Question 23. How and where can I control whether a repeat delta is requested?
Answer:
Via the status of the last delta in the BW Request Monitor. If the request is RED, the next load will be of type 'Repeat'. If you need to repeat the last load for any reason, manually set the request in the monitor to red. For the contents of the repeat, see Question 14. Delta requests set to red when data is already updated lead to duplicate records in a subsequent repeat, if they have not already been deleted from the data targets concerned.
Question 24.
As of PI 2003.1, the Logistic Cockpit offers various types of update methods. Which update method is recommended in logistics? According to which criteria should the decision be made? How can I choose an update method in logistics?
Answer:
See the recommendation in Note 505700.
Question 25.
Are there particular recommendations regarding the maximum data volume of the delta queue to avoid danger of a read failure due to memory problems?
Answer:
There is no strict limit (except for the restricted number area of the 24-digit QCOUNT counter in the LUW management table - which is of no practical importance, however - or the restrictions regarding the volume and number of records in a database table).
When estimating "soft" limits, both the number of LUWs and the average data volume per LUW are important. As a rule, we recommend bundling data (usually documents) as soon as you write to the delta queue to keep number of LUWs low (this can partly be set in the applications, for example in the Logistics Cockpit). The data volume of a single LUW should not be much larger than 10% of the memory available to the work process for data extraction (in a 32-bit architecture with a memory volume of about 1 GByte per work process, 100 MByte per LUW should not be exceeded). This limit is of rather small practical importance as well since a comparable limit already applies when writing to the delta queue. If the limit is observed, correct reading is guaranteed in most cases.
If the number of LUWs cannot be reduced by bundling application transactions, you should at least make sure that the data is fetched from all connected BWs as quickly as possible. But for other, BW-specific, reasons, the frequency should not exceed one delta request per hour.
To avoid memory problems, a program-internal limit ensures that no more than 1 million LUWs are ever read and fetched from the database per delta request. If this limit is reached within a request, the delta queue must be emptied by several successive delta requests. We recommend, however, to try not to reach that limit but trigger the fetching of data from the connected BWs as soon as the number of LUWs reaches a 5-digit value.

PO split in sourcing cockpit ? :-(
Hello my helpful friends.je.je
I have quick question for the SRM gurus:
In the sourcing cockpit, I selected 20 items (per example) and the application splits those items among 2 purchase orders.
What is the reason of this behavior ? I know that ebp separates direct and indirect materials. But in this case everything is indirect.
Is there any field that may cause a PO split ?
Thanks and regards from Mexico !
diegoFollowing is the criteria which is used to split POs
For Backend Purchase Orders
Company Code
Purchasing Org
Purchasing Group
Document Type
Vendor
Subtype (Direct/Hierarchy)
FI Logical System
Logical System from where an External Requirement comes
For Local Purchase Orders additional criteria is used to split POs:
Delivery Address (for higher releases)
Procument Card Number
Procurement Card Company
Additionaly as mentioned by Vadim, check the Implementation of BADI BBP_SC_TRANSFER_BE (Method GROUP_PO) for any Customer Added Splitting Criteria.
Thanks,
Ashish
