Infospoke question
Hi experts,
We have an infospoke which is pulling data from a cube via delta mode. We noticed in the past weeks that whenever the infospoke is reading two requests from the cube with 0 added, it is somehow pulling data via full extraction. When I checked the table I see documents created 2 years ago. This should not be happening because it's a delta extraction mode. We never had this problem before in BW 3.5, it all started after our system upgraded to BI 7. I read something about cube compression that might affect infospoke performance but we don't have compression in the cube.
Has anyone experienced the same problem? We appreciate any information that could shed some light on this issue.
Thanks in advance.

Hi Jasprit,
Here is the code:
data: l_s_data_in type /bic/cytest,
l_s_data_out type /bic/cztest.
loop at i_t_data_in into l_s_data_in.
l_s_data_out-/bic/zbumtolb = l_s_data_in-/bic/zbumtolb.
insert l_s_data_out into table e_t_data_out.
endloop.
Thanks

Is there a way to set all requests in a delta infospoke from "Not Yet Read" (Yellow) to "Read" (Green) without doing an extract?? I see how to set it from Read to Not Yet Read, but I want to go the other way.
Hi..
I have missed a Delta in the Infospoke. I re ran it again.. But got only zero records, thought there is 1850 delta records. Is it possible to get back the delta records??
Thanks in Advance -
Infospoke logical file name question
Experts,
We have what seems to be an anomaly that we need to understand.
On the application server, when we extract our infospokes, two files are generated , a schema and a data file.
the naming convention is like
zxxx.infoprovider_date
eg. zxxx.infoprovider_20080501
now what happens is,
sometimes, some data files,
come out on the application server with the name
zxxx.infoprovider_1date
These are the same files that came out fine(without the '1') on a previous date .
Also there are no duplicate files on the same date .
Any ideas what could be causing this change in file name?
Thanks

Hello
We have a problem regarding infospokes. We have edited some infoobjects and infoprovider. We want to know if this action deactivated related infospokes. How do we know what infospokes are related to the infoprovider so that we can track if the action we have done deactivated the related infospokes,
Thanks a lot!

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 -

B)
9) Describe experience with ABAP
10) Describe any hands on experience with ASAP Methodology.
11) Identify SAP functional areas (SEM, CRM, etc.) you have experience in. Describe that experience.
12) What is partitioning and what are the benefits of partitioning in an InfoCube?
A) Partitioning is the method of dividing a table (either column wise or row wise) based on the fields available which would enable a quick reference for the intended values of the fields in the table. By partitioning an infocube, the reporting performance is enhanced because it is easier to search in smaller tables. Also table maintenance becomes easier.
13) What does Rollup do?
A) Rollup creates aggregates in an infocube whenever new data is loaded.
14) What are the inputs for an infoset?
A) The inputs for an infoset are ODS objects and InfoObjects (with master data or text).
15) What internally happens when BW objects like Info Object, Info Cube or ODS are created and activated?
A) When an InfoObject, InfoCube or ODS object is created, BW maintains a saved version of that object but does not make it available for use. Once the object is activated, BW creates an active version that is available for use.
16) What is the maximum number of key fields that you can have in an ODS object?
A) 16.
17) What is the specific advantage of LO extraction over LIS extraction?
A) The load performance of LO extraction is better than that of LIS. In LIS two tables are used for delta management that is cumbersome. In LO only one delta queue is used for delta management.
18) What is the importance of 0REQUID?
A) It is the InfoObject for Request id. OREQUID enables BW to distinguish between different data records.
19) Can you add programs in the scheduler?
A) Yes. Through event handling.
20) What is the importance of the table ROIDOCPRMS?
A) It is an IDOC parameter source system. This table contains the details of the data transfer like the source system of the data, data packet size, maximum number of lines in a data packet, etc. The data packet size can be changed through the control parameters option on SBIW i.e., the contents of this table can be changed.
21) What is the importance of 'start routine' in update rules?
A) A Start routine is a user exit that can be executed before the update rule starts to allow more complex computations for a key figure or a characteristic. The start routine has no return value. Its purpose is to execute preliminary calculations and to store them in a global data structure. You can access this structure or table in the other routines.
22) When is IDOC data transfer used?
A) IDOCs are used for communication between logical systems like SAP R/3, R/2 and non-SAP systems using ALE and for communication between an SAP R/3 system and a non-SAP system. In BW, an IDOC is a data container for data exchange between SAP systems or between SAP systems and external systems based on an EDI interface. IDOCs support limited file size of 1000 bytes. So IDOCs are not used when loading data into PSA since data there is more detailed. It is used when the file size is lesser than 1000 bytes.
23) What is partitioning characteristic in CO-PA used for?
A) For easier parallel search and load of data.
24) What is the advantage of BW reporting on CO-PA data compared with directly running the queries on CO-PA?
A) BW has a better performance advantage over reporting in R/3. For a huge amount of data, the R/3 reporting tool is at a serious disadvantage because R/3 is modeled as an OLTP system and is good for transaction processing rather than analytical processing.
25) What is the function of BW statistics cube?
A) BW statistics cube contains the data related to the reporting performance and the data loads of all the InfoCubes in the BW system.
26) When an ODS is in 'overwrite' mode, does uploading the same data again and again create new entries in the change log each time data is uploaded?
A) No.
27) What is the function of 'selective deletion' tab in the manage->contents of an infocube?
A) It allows us to select a particular value of a particular field and delete its contents.
28) When we collapse an infocube, is the consolidated data stored in the same infocubeinfocube? or is it stored in the new
A) Data is stored in the same cube.
29) What is the effect of aggregation on the performance? Are there any negative effects on the performance?
A) Aggregation improves the performance in reporting.
30) What happens when you load transaction data without loading master data?
A) The transaction data gets loaded and the master data fields remain blank.
31) When given a choice between a single infocube and multiple InfoCubes with a multiprovider, what factors does one need to consider before making a decision?
A) One would have to see if the InfoCubes are used individually. If these cubes are often used individually, then it is better to go for a multiprovider with many cubes since the reporting would be faster for an individual cube query rather than for a big cube with lot of data.
32) How many hierarchy levels can be created for a characteristic info object?
A) Maximum of 98 levels.
33) What is open hub service?
A) The open hub service enables you to distribute data from an SAP BW system into external data marts, analytical applications, and other applications. With this, you can ensure controlled distribution using several systems. The central object for the export of data is the Infospoke. Using this, you can define the object from which the data comes and into which target it is transferred. Through the open hub service, SAP 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.
34) What is the function of 'reconstruction' tab in an infocube?
A) It reconstructs the deleted requests from the infocube. If a request has been deleted and later someone wants the data records of that request to be added to the infocube, one can use the reconstruction tab to add those records. It goes to the PSA and brings the data to the infocube.
35) What are secondary indexes with respect to InfoCubes?
A) Index created in addition to the primary index of the infocube. When you activate a table in the ABAP Dictionary, an index is created on the primary key fields of the table. Further indexes created for the table are called secondary indexes.
36) What is DB connect and where is it used?
A) DB connect is database connecting piece of program. It is used in connecting third party tools with BW for reporting purpose.
37) Can we extract hierarchies from R/3 for CO-PA?
A) No We cannot, NO hierarchies in CO/PA�?.
38) Explain field name for partitioning in CO-PA
A) The CO/PA partitioning is used to decrease package size (eg: company code)
39) What is V3 update method ?
A) It is a program in R/3 source system that schedules batch jobs to update extract structure to data source collectively.
40) Differences between serialized and non-serialized V3 updates
41) What is the common method of finding the tables used in any R/3 extraction
A) By using the transaction LISTSCHEMA we can navigate the tables.
42) Differences between table view and infoset query
A) An InfoSet Query is a query using flat tables.
43) How to load data from one InfoCube to another InfoCube ?
A) Thro DataMarts data can be loaded from one InfoCube to another InfoCube.
44) What is the significance of setup tables in LO extractions ?
A) It adds the Selection Criteria to the LO extraction.
45) Difference between extract structure and datasource
A) In Datasource we define the data from diff source sys,where as in extract struct it contains the replicated data of datasource n where in we can define extract rules, n transfer rules
B) Extract Structure is a record layout of InfoObjects.
C) Extract Structure is created on SAP BW system.
46) What happens internally when Delta is Initialized
47) What is referential integrity mechanism ?
A) Referential integrity is the property that guarantees that values from one column depend on values from another column.This property is enforced through integrity constraints.
48) What is activation of extract structure in LO ?
49) What is the difference between Info IDoc and data IDoc ?
50) What is D-Management in LO ?
A) It is a method used in delta update methods, which is based on change log in LO.

How can a planning version be frozen and unfrozen?
A Planning Version can be frozen and unfrozen using Function Module /SAPAPO/TS_PAREA_VERSIO_FREEZE so that no further changes to the planning version can be done.
What is Release Profile?
Release Profile is used to release timeseries data from DP to SNP/PPDS. You need to define the DP Planning Area and timeseries keyfigure the data in which is released and the SNP Category Type (typically FA) to which data is released. You may maintain a Daily Buckets Profile it will define the number of working days (working days determined based on Shipping Calendar maintained for the location master) starting on and from the From Date if released online/ interactively or that many workdays of the planning horizon when release is carried out in background. The Period Split (blank, 1 and 2) field in the SNP2 tab of location-product master determines how demand plan is released to SNP from DP (how bucketed data is disaggregated to the workdays).
What is the usage of Period Factor?
Period Factor maintained in the SNP PPM or Transportation Lane determines the Availability Date of a Receipt element within a time bucket (period). The system determines the exact availability date/time of the receipt elements within a period, by adding a time interval (that it gets by multiplying the period factor with the period length) to the start time of the period. You can enter a factor between 0 and 1, where 0 is the start of the period, 0.5 the middle, and 1 the end of the period. When calculating the availability date/time, the system takes into consideration all weekdays, meaning that it does not take into consideration any days that have been defined as non-workdays in the calendars.
Period Factor used is .71 = 7x0.71 = 4.97 or 5 days from ptimizer of weekly bucket resulting in a Friday.
If Period Factor is not maintained in PPM or Transportation Lane then the User Period Factor indicator and the Period Factor value maintained in the Lot Size tab of the location-product combination is used. If this is not maintained a default value of 0.5 is used.
What determines stock categories displayed in Stock on Hand keyfigure?
The categories defined in Category Group ST1 (can be maintained in table /SAPAPO/APOCGC) determine the stock categories that are displayed in the Initial bucket in the Stock on Hand keyfigure. Subsequent buckets are dynamically computed.
Does dynamic alerts show up in Alert Monitor?
Dynamic Alerts do not show up in the stand-alone alert monitor. Network alerts are to show pegging relationships.
What is the report to execute MASSD?
The report for executing MassD in background job is MASSBACK.
What is the shortcut to change location type in APO?
Report /SAPAPO/CHECK_LOCATION_TYPE can be used to change location type (say from 1001 to 1002 or vice-versa) of existing locations in APO. The table to refer is /SAPAPO/LOCMAP. SAP does not recommend this process.
How can a transaction be executed even when no authorization?
SE93 - Transaction code for Transaction Code E.g. CRC1 Create Resource has txn code CRAH. So if you do not have authorization to create resource you can use SE93 and enter txn CRAH and then Test F8 button to go to the txn.
How to copy a Process Chain?
To copy a process chain to another process chain, goto the Process Chain you want to copy and then type copy in the tool tar and hit enter. It will allow you to copy the Process Chain to another Process Chain that can be modified as per user's requirement, saved, activated and used.
What is the process to copy planning versions in R/3?

In InfoSpoke logical path made generic across landscapes
Hi all,
I am creating an InfoSpoke in 3.5, wherein I am using logical file/Path to store the file generated on application server.
My path is something like this
/interface/CCD/BWD/outbound.. (Where BWD is development server)
When I will transport this to quality (Say BWQ), i want my path to be
/interface/CCQ/BWQ/outbound..
I am using <SYSID> variable to replace BWD part of the path. When it will be transported in Quality variable <SYSID> will contain BWQ.
My question is what system variable i can use to replace CCD in the path? Or how can I create a new variable to replace CCD in path so that in Quality it will be CCQ?I never used profile parameters.
I looked at
http://help.sap.com/saphelp_nw04/helpdata/EN/c4/3a6247505211d189550000e829fbbd/frameset.htm
It explains that no server should have to be restarted (as you also expect), so i don't get the problem.
Maybe a question for the technical guys? -
Infospokes -Data transfer to third party
Hello Folks,
Im now working on SAP BW 3.5 system. I need to transfer data from SAP BW DSO/ODS object to an Oracle Database. I am thinking of using Infospokes to achieve this requirement.
My findings: In the Destination tab of the Infospoke maintanence screen (RSBO), i see that there is an option to send data through "RFC destination". But, my understanding is that RFC destination could possibly be to an another SAP system and not an Oracle database which is through the DB connect.
My questions:
1) Can i transfer data from ODS to Oracle database through Infospokes?? If yes, how?
2)If not, is there an other way to transfer data to Oracle database directly?
Request the experts out there to help me with this.
Thank You

PrashantI think Infospoke is the better option. You can download the data in file or in a table.
But I dont know how to upload the file in Oracle, dont have any experience -
Hi Experts,
i just wanted to create an infospoke on query results, i mean to say what ever the the data coming when i execute the query tht should come through info spoke..
now my question is if i create infospoke on multi provider, does it support delta??
and Infospokes does support to bring hirachies data if yes how we can bring hirarchies data??
thanks for your time..
Regards,
MarjunYes, use BAPI directly instead of infospoke.
Infospoke supports Delta, not sure of Heirarchies(i dont think so).

BADI Implementation for INFOSPOKE
Hi,
I have a BADI logic to read the product description from the text table in my infospoke and writing into a file.
I have multiple(10) infospoke extraction (same format but with different selections) which wants to use the similar type of logic.
My question is:
Is it possible to write one Generic BADI and that can be shared by other infospoke extractions?
OR should I copy the same logic for other 10 BADI ?
I believe the BADI is specific to infospoke. I see that I have no control over the source structure...
2) I was trying this in RSCRM_BAPI. My query result in BEX shows the product and product description(from text table)fine. where as in my RSCRM_BAPI it displays only the product and NOT the description. If I could able to display the text using RSCRM_BAPI I can define 10 queries which makes my life easier...
Any idea/suggestion in both methods is greatly appreciated as this is kind of very URGENT..
Thanks for you help.This is kind of URGENT.
Any help will be very useful -
I am using infospoke to extract data. I am using DB table as destination. My question is do we need to create the DBTABLE ?. and i want to transport these spokes to quality system. do i need to make sure these DB table are already existing in the Quality system before transport?/

Hi All,
In BW 7 We are using Open Hub & previously using Infospoke in BW 3.5. My question is in infospoke we have the flexibility of using BADI but in Open Hub we dont have that option. can we still use infospoke instead of Open HUB. Are there any advantages of open hub over infospoke.
Thanks,
Kiran.Hi,
The open hub service enables you to distribute data from an SAP BW system into external data marts, analytical applications, and other applications. With this, you can ensure controlled distribution using several systems. The central object for the export of data is the InfoSpoke. Using this, you can define the object from which the data comes and into which target it is transferred.
Through the open hub service, SAP 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.
Functions
BW objects such as InfoCubes, ODS objects, or InfoObjects (attributes or texts) can act as open hub data sources. You can select database tables or flat files as open hub destinations. Both a full and a delta mode are also available as the extraction mode.
Components of the Open Hub Service
The open hub service is made up of the following objects:
InfoSpoke
The central object for the data export is the InfoSpoke.
The InfoSpoke defines the following:
u2022 The open hub data source from which the data is extracted
u2022 The extraction mode
u2022 The open hub destination into which the data is delivered.
In addition, you can also select which data selection is to be extracted from which InfoProviders. This selection ensures that a destination for different points in time from the same InfoProvider can be supplied with data for different selection criteria using a delta. The selection set is freely configurable as long as extraction has not taken place in the delta mode. Once it has, this no longer applies.
Open Hub Data Source
BW objects such as InfoCubes, ODS objects, MultiProviders and MultiProviders and InfoObjects (attributes or texts) can function as open hub data sources. If you use an InfoCube with non-cumulative key figures as a data source, refer to the note regarding the settings on the Selection tab page in Creating InfoSpokes.
Extraction Mode
An InfoSpoke can extract data in two ways: in full mode (F) and in delta mode (D). See InfoSpoke Extraction Mode.
Open Hub Destination
Database tables (from the database in the BW system) and flat files (CSV) can act as open hub destinations. See also Extraction to Database Tables and Extraction to Flat Files. You can extract the data from a database to a non-SAP system using APIs with a third-party tool. See also Extraction to Non-SAP Systems.
The open hub destination includes all information about a target system for the InfoProvider data: type of destination, name of the flat file or the database table. It also contains a logical target system. The logical target system is used to structure the individual open hub destinations in the open hub monitor. The open hub monitor groups the requests according to logical target system, open hub destination and InfoSpoke. By specifying a logical target system, you get a better overview of the individual open hub requests.

@AK -
I have an InfoSpoke that I would like to rerun as a FULL. The InfoSpoke was transported to production with "Delta" as it's Extraction Mode and ran for the first time 05/18/2007. It has been run 2-3 times since in Delta mode. In production we can NOT change it from a DELTA to a FULL. The questions:
1.) The first time an InfoSpoke is run in "Delta" extraction mode does it do a FULL extraction.
2.) What is the procedure to reinitalize an InfoSpoke after several delta runs and rerun it so that a FULL extraction is performed.
Your help is appreciated. Thank you,
DaveAbhishek,
Thank you for your response. Does "deactivating" the delta, then exiting out of the Delta Administration popup window, and then going into it and activating the delta again reinitialize the InfoSpoke so that the next run would be a FULL?
It is not clear from looking at the status of the InfoSpoke requests before and after the deactivation if it is ignoring all previous delta requests and doing a full or if it is just doing another delta.
Thank you,
Dave
