Project Plan for "SAP BW Implimentation" project.

Hi All,
My name is Rajasekhar. I am a BW consultant. I would like to know the standard template for PP ( Project Plan ) for SAP BW Implimentation Project.
1) Could you please suggest me any link available in SAP to get the Project Plan and related documents.
2) In some of the BW books, it is mentioned that the standared project plan recommended by SAP is "ETBWPP03.doc". I couldn't find this document also. If you know the link, request you provide the info.
Full points willl be awarded for the best reply.
Thanks & Regards,
Raj.

ASAP V3.7: roadmap for SAP BI

Hello all,
if you hit page <a href="https://websmp209.sap-ag.de/~form/sapnet?_SHORTKEY=01100035870000420636&_SCENARIO=01100035870000000202">ASAP Implementation Roadmap</a> (SMP login required), you'll see what's new in ASAP Implementation V3.7 (June 2007) release of the roadmap.
Interestingly, this version provides:
* New roadmap content for SAP Business Intelligence
Completely new content for business process requirements gathering, solution configuration and testing of SAP Business Intelligence
I've downloaded the Complete View, the Methods View and the Output View of ASAP Implementation Roadmap V3.7. However I can't find the referred roadmap content about SAP BI.
Have you got any idea about where I can find it?

Implementing ASAP Methodology using SAP Solution Manager

Hi All,
Can any one help me with any documentation regarding ASAP methodology implementation using Solution Manager.
The step by step process and transaction codes used for implementing it are there any guides provided by SAP for implementing the ASAP methodology in Solman.
It's an implementation project that we would like to track each phase in Solman.
Kindly help me to get more details.
Thanks in advance.

Hi,
There are the 'ASAP Implementaion Roadmaps' wheras the latest available
is the 'ASAP Methodology for Implementation 7.0' Roadmap, and there are
the 'Upgrade Roadmaps' wheras teh lastest one of them is:
'Upgrade Roadmap (V3.2)'.
If you are on ST-ICO 150 SP24 both of these Roadmaps
should be available in your system.
There are two ways to display the roadmaps in RMMAIN.
One is to choose a project in RMMAIN, then the roadmap assigned to
the project in SOLAR_PROJECT_ADMIN is displayed.
The other one is to display any available roadmap in the system
To display one of the available roadmaps (without a project) choose
the button 'Other Roadmap' in RMMAIN and in the upcomming popup
hit the button 'No Project'.
After that you should get an addtional button besides the Project
button called Roadmaps (Other Roadmap).
When you hit now this button you will get a list of all available
roadmaps.
Some further notes for referencing (although they can be old but still helpful)

Hi,
Thnx a lot for the suggestion Markus
I have created the directories required.
The SAP installation has started, but now I am getting the message as below during the ORACLE DB Installation phase,when I run the Oracle ./RUNINSTALLER in Bash Unix:-

export ORACLE_HOME
But I get the same message again as above.
Do we need to set the ORACLE_HOME env variable in the BASH_PROFILE directly??? Coz I heard that if we set it with the Export command then the env is set only for the current instance and not permanently.
If so what is the exact entry I need to make in the BASH_PROFILE???

"Case use" technique for SAP implementation?

Hello all,
has anyone used "case use" technique for SAP implementation? I mean for standard process, not only developing.
Any recommendation about it?
Thanks in advance and best regards,
Adolfo

It would be helpful to go through the help document of ASAP Methodology.
The following information may clarify some doubts/requirements you have.
Generating the Project IMG through ASAP:
After you have set the project scope, the next step is to generate the Project IMG. From the Business Process Master List (BPML), you can directly access the IMG activities relevant for configuring each process.
BPML: The Business Process Master List, along with the Business Blueprint, is a key result of the second phase of the Roadmap. Microsoft Excel tables contain the SAP scenarios, process groups, and processes that have been set in scope in the SAP Reference Structure, and are crucial for configuring your SAP System. In Realization, the third phase of the Roadmap, the BPML provides the basis for monitoring and steering test activities and for configuring your SAP System. It contains the titles of the structure items, and displays the status, the owner, links to documentation and links to the SAP System. Amongst other things, the BPML allows you to:
1) Set your baseline and final scope. These are used for baseline and final configuration.
2) Access the Project IMG and specific IMG activities assigned to structure items.
3) Access integration test plans, which help you carry out all required integration tests.
The Prerequisite is you have set the project scope.
Process Flow to use the Business Blueprint as a basis for configuring your SAP System:
1) Set the project scope.
2) Generate the Project IMG.
3) Generate the BPML.
4) From a specific processes in the BPML, you can go to the relevant IMG activities and make Customizing settings.

FAQS FOR SAP BW

HI,
friends i need some FAQS for the interviews .
thanks and regards
shafeeq ahmed

Hi Shafeed,
Here are some questions and answers.
1)name the two table that providedetail information about data source
2)how and when can you control whether repeat delta is requested?
3)how can you improve the performance of aquery
4)how to prevent duplicate record in at the data target level
5)what is virtual cube?its significance
6)diff methods of generic datasource
7)how to connect anew data target to an existing data flow
8)what is partition
9) SAP batch process
10)how do you improve the info cube design preformance
12)is there any diff between repair run/repaire request.if yes then please tell me in detail
13)difference between process chain and infopackage group
diff between partition/aggregate
ANS--
1)   Hi Santosh
Please find some of the answers here...
For Q 3) Query Performance can be improved by making the Aggregates having all the Chars & KF used in Query.
Q 5) Virtual Cube : InfoProvider with transaction data that is not stored in the object itself, but which is read directly for analysis and reporting purposes. The relevant data can be from the BI system or from other SAP or non-SAP systems.
VirtualProviders only allow read access to data.
Q 6) Diff Methods of Generic datasource using Transaction RSO2 :
a) Extraction from DB Table or View
b) Extraction from SAP Query
c) Extraction by Function Module
2) Important BW datasource relevant tables
ROOSOURCE: Table Header for SAP BW OLTP Sources
RODELTAM: BW Delta Process
ROOSFIELD: DataSource Fields
ROOSGEN: Generated Objects for OLTP Source, Last changed date and who etc.
3)     For Q 8) i think you mean table partition
You use partition to improve performance. You can only partiton on 0CALMONTH or 0FISCPER
4)     1. ROOSOURCE
6. Generic Extarction using 1.Views 2. Infoset Queries , 3. Function modules
5)     Hi Santosh
Pls note down the Q& ANS
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) 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 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 additio

Project Time estimate for SAP BI

Hi Experts,
Can somebody please give me the time estimate for SAP BI project.
I am supposed to give effort analysis for BI implementation project.
Thanks in Advance.

If you know the scope of the project you can give rough estimate. Scoping gives you idea about number of Business process to be mapped in BI, number of reports required, criticality of report. The timing will alos depend upon the standard /customized content and enhancement done in source system. If there are independent business process you can reduce the implementation time by increaing the resources for the project.
If you want to get idea about time check the ASAP methodology and see how much time you need for each step of project plan. Roughly you will get the time.
Regards,
Kams

"Case use" technique for SAP ERP implementation?

Hello all,
has anyone used "case use" technique for SAP implementation? I mean for standard process, not only developing.
Any recommendation about it?
Thanks in advance and best regards,
Adolfo

It would be helpful to go through the help document of ASAP Methodology.
The following information may clarify some doubts/requirements you have.
Generating the Project IMG through ASAP:
After you have set the project scope, the next step is to generate the Project IMG. From the Business Process Master List (BPML), you can directly access the IMG activities relevant for configuring each process.
BPML: The Business Process Master List, along with the Business Blueprint, is a key result of the second phase of the Roadmap. Microsoft Excel tables contain the SAP scenarios, process groups, and processes that have been set in scope in the SAP Reference Structure, and are crucial for configuring your SAP System. In Realization, the third phase of the Roadmap, the BPML provides the basis for monitoring and steering test activities and for configuring your SAP System. It contains the titles of the structure items, and displays the status, the owner, links to documentation and links to the SAP System. Amongst other things, the BPML allows you to:
1) Set your baseline and final scope. These are used for baseline and final configuration.
2) Access the Project IMG and specific IMG activities assigned to structure items.
3) Access integration test plans, which help you carry out all required integration tests.
The Prerequisite is you have set the project scope.
Process Flow to use the Business Blueprint as a basis for configuring your SAP System:
1) Set the project scope.
2) Generate the Project IMG.
3) Generate the BPML.
4) From a specific processes in the BPML, you can go to the relevant IMG activities and make Customizing settings.

Control M Job for SAP

I have not worked in control M job for SAP.
Can anyone explain how to install control M enterprise manager and configure for SAP.
Clearly define all the steps.
How this control M job different from the jobs scheduled via SAP TRANSACTIONS -SM37.
What is the purpose of Control M job , how to relate this to SAP.
Expecting solution ASAP.
Thanks.

the whole logic in control M is, they dont schedule periodic jobs in SAP. they do a adhoc submit to SAP...
like SUBMIT program XYZ with ... .... ...
so, the schedule happens in CONTROL-M.. they define when to start the submit statement.. and they connect though RFC.
that means, what you think that in SAP a periodic job is running, but in actual case its a adhoc job.
how to install control-m, get in touch with their customer support

Virtualization for SAP solutions

Hi all,
as i recently wrote a blog about 'Virtualization and enterprise SOA' and as we will have many virtualization related activities in 2007 i think it's a good idea to start a thread in this forum for general discussion about virtualization and its utilization in SAP landscapes.
As many of you know SAP is offering application virtualization capabilities in SAP NetWeaver with Adaptive Computing. This was introduced in at SAPPHIRE 2004.
Meanwhile virtualization concepts, technologies and products cover a much broader part of an SAP landscape, starting at network virtualization and going up to desktop virtualization. I am sure storage virtualization with SAN or NAS is almost a standard IT scenario, but some of the newer virtualization technologies are in their early stages first.
How are you using virtualization technologies today, and which concepts/products/... do you consider to be most important for your environment ?
Best regards
Roland

Hi Kwee,
my name is Nils and I am topic owner of the virtualization topic within SAP Consulting. You ask:
1. How will SAP system maintenance and administration be affected now that we have tools in VM that can hanlde copying, backup and recovery?
Generally spoken, SAP should react on this when it comes to cloning instances. Change of an SID still is not supported, so I would expect the SAP Virtualization Lab to provide a solution for this demand asap.
In the VMware context, our Consulting team developped an approach that lets you run SAPINST in a silent mode so that no user interaction is needed any more for installing application servers, central instances and so on. You create a master template for sapinst, and this template can then be modified script-based to deploy your dialog instances in background. Siemens implemented our solution as well as MAN Diesel in Kopenhagen
If you have customers who deal with this topic, ask them to order me for an implementation. Backup and recovery should still be performed on database or storage level (Netapp). If you ask the question more precisely, I will give you a more detailed answer.
2. What about SAP high availability and disaster recovery scenarios? How useful is clustering now that we have tools in VM that can offer an alternative solution?
Clustering still remains one of the operational keys. VMWare can never fully replace a Cluster although the fancy VMWare slides would like to make us thinking so. When it comes to disaster recovery, VMWare HA is a very fancy solution. But not every customer has the infrastructure and the money to implement VMWare HA. Also from a performance point of view, Clustering still stays a valid approach. Or did you ever try a HA-setup for a 8 TB solution with VMWare? A valid alternative for Clustering can be Adaptive Computing which gives you an enhanced availability (no high availability) bit downtimes of customer sometimes allow this and it is more stable than most cluster solutions around. You should also keep your eyes on Windows Server 2008! I spoke to Microsoft this week, and they put live-migration of virtual machines on their hot topic list again (after it was removed). Beginning of 2009, Windows Server will be able to migrate virtual machines in a live manner and also provide HA functionality for virtual machines. VMWare is still a little bit ahead of MS, but I saw the newest tools from MS, and this advantage is shrinking.
3. How will hardware sizing be handled for SAP upgrades and rollout of new functions in a VM architecture?
From a sizing perspecive, calculate an overhead of 20% for your hardware to be on the safe side. Sizing is a task to be done by the customer together with the hardware vendor. He needs to tell the vendor that he wants to operate SAP in a virtualized environment. The hard limit for this is the IO based on your approach how to host the virtual systems (VMFS based with central FC storage or container- based). The hard limit is 6000 SAPs at the moment, for larger implementations, a lot of money has to be spent, technically, more then 18.000 SAPs are possible (but do not make sense).
4. How can performance be optimized in a VM environment?
SAP-Performance? IO-Performance? There are some guidelines when it comes to the setup of virtual machines with SAP. You can find them here:
http://www.vmware.com/partners/alliances/technology/sap-whitepapers.html
Best Practice Guidelines for SAP Solutions on VMware® Infrastructure
Is there a SAP training that specifically deals with such topics?
No, but if you can take care on an IO, I could come over and teach you and your collegues about those topics. I developped a workshop I present to customers (one-day) about all of those topics mentioned here.
Best regards,
Nils, Technical Solution Architect, SAP Consulting
