Table splitting for SAP Migration

Hi ,
The table splitting preparation through SAPINST takes long time.
How soon can we start the tablesplitting preparation before the export?
can we start at command level without SAPINST?
Thanks,
Chitra

Hi Chitra,
Table splitting time depends upon number of tables for which table splitting needs to be done, no of parallel jobs and version of R3ta, R3load and R3szchk files.
How many tables are your splitting ?
How many parallel jobs have u defined ?
Have you updated R3ta, R3load and R3szchk ?
Regards,
Deepak Kori

Deactivate table locks for SAP courses

Hello,
when visiting SAP courses in Walldorf, I observed that it was possible that all participants where able to maintain the same customizing table without getting informed that the table is locked.
How can this behaviour be achived? Usually only one user is able to maintain a table at a time, however, especially for SAP courses it would be great to deactivate this.
Any ideas?
Thanks & regards
Wolfgang

Hello all,
if this is still interesting for someone:
I found this page http://****************/Tutorials/ABAP/Lock/Page1.htm where they explain how to create a special report that will call the customizing view for a specific table in a different mode.
The report will delete the general table lock and create row-based locks (based on key fields) instead, allowing at least several users to work with the same table - as long as they edit entries that have different key fields.
I haven't tried it yet, but it looks promising...
Best regards
Tobias

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) 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

Table Link for EQUNR (Eqpt Number) and GEWRK (Main Work Center)

Hello,
I need to fetch the main work center from equipment master. I need a direct table link between the equipment number and mainwork center. We are getting a link of equipment number (EQUNR) to work center (ARBPL) and a link of work center (ARBPL) to main work center (GEWRK). But the problem with this scenario is - main work center is not getting fetched from equipment master once work center is missing.
We want a direct link through some table between EQUNR and GEWRK.
Puneet

Hi Puneet,
Appreciate your problem !
Many a times in such a situation (which I presume exists where no direct link is available between fields); we have 2 clear cut approaches -
Approach 1:
Develop a SAP Query, Functional Area/Infoset, and User Group ( using T code :SQ03,SQ02,SQ01 respectively )
While developing Functional Area feed in these 2 tables (Table 1- equipment number (EQUNR) & work center (ARBPL) and Table 2 - work center (ARBPL) to main work center (GEWRK) with work center (ARBPL) as the Primary Key- bridge to join these 2 tables.
In SAP Query Development; you may take Plant as the Selection Field or any other field as per business requirement to make a search in the query.
Now when you execute this query, you will get a complete Download of (EQUNR),work center (ARBPL) and main work center (GEWRK) in one table.
For SAP Query, you may also approach your ABAP Team Member. This is a cleaner approach than the other one.
Approach 2:
Take SE16 download of the Table 1 and Table 2 and join them in Excel (using vlookup if required).This approach is however limited to the data volume that you have to process.
Please let me know, if you get stuck !
Thanks,
RAVI.

RDS for SAP data migration through IDOC's

Dear Experts
Just now we have installed BODS 4.1 and RDS also installed now. I am in the process of exploring the RDS. I found all the migration objects is available in the form of IDOC's. Now my questions are
How to work on custom IDOC's. Do i need to extensively code on R/3 side to upload the custom fields. Like user exit or BADI for custom fileds
If yes then i would say implementation time through RDS will remain more or less same time.
Through BODS or by RDS migration objects is there any way without coding on ABAP R/3 side, Can we achieve migrating custom fields
Please let me how to achieve above requirements by RDS
Thanks
Vijay Mukunthan

Hi Vijay,
You are right, the standard content of the Rapid Data Migration RDS packages brings the content with the standard IDoc interface for SAP standard only. So custom objects are not pre-built with the package. However, we incorporated the foundation to include custom coding as easy as possible:
1) IDoc
We are using the standard interface technology IDoc. IDocs do have an enhancement concept which is described in the online help. There are three main cases and all of them are supported, however two need additional coding:
Z-fields: Additional fields in existing tables lead to IDoc segment extensions
With the IDoc segment versioning concept this is easy to realize without any ABAP coding
Z-tables: Additional IDoc segments will be necessary and lead to a new IDoc version
With the IDoc versioning concept you can easily add Z-segments with leveraging provided user exits
Custom business objects:
You can even create a complete own IDoc message type in Z-namespace for own stuff, leveraging the given ALE layer of the IDoc middleware
2) Enhancement guide
With the RDS package we offer an enhancement guide which helps you to modify the jobs and data flows in the SAP Data Services content according to the changes in the target IDoc structure to reflect additional fields and tables. We built it as a step-by-step guide following for a sample IDoc type but will work similarly for any IDoc.
Best regards,
Frank Densborn.

Table split method Error - DB migration

Hi,
We are installing NW730,
Migration details : oracle/solaris to DB2/Solaris
Table split preparation failed with "R3ta failed for table REPOSRC"
Also, am not sure about the below parameter which i gave during the "table spliting preparation"
Database type : Oracle
Thanks in Advance.

Hi,
Do you create table splitting file for table REPOSRC?
for eg:
REPOSRC%4;PROGNAME
Perform a search on SDN and you'll find useful info in table splitting.
Cheers,
Thanks,

ABAP transformation to XML for sap chart engine with internal table

Hello.
I am new to the SAP chart engine, XML and transformations so please be patient with me from an ABAP-program I am trying to call a Z-transformation and attach an internal table with two columns. In the ST program I want to loop through the table and for each row insert the two values from the table in the XML.
In an ABAP-program I have an internal table containing datacoordinates for a scattered chart.
The table looks like this:
DATA: BEGIN OF coordinate,
            x_value TYPE f,
            y_value TYPE f,
           END OF coordinate,
           polygon_data LIKE STANDARD TABLE OF coordinate with header line.
As a prototype I just add a few coordinates like this:
polygon_data-x_value = '700'.
    polygon_data-y_value = '8'.
    APPEND polygon_data.
    polygon_data-x_value = '1400'.
    polygon_data-y_value = '3'.
    APPEND polygon_data.
    polygon_data-x_value = '1400'.
    polygon_data-y_value = '10'.
    APPEND polygon_data.
    polygon_data-x_value = '700'.
    polygon_data-y_value = '10'.
    APPEND polygon_data.
    polygon_data-x_value = '700'.
    polygon_data-y_value = '3'.
    APPEND polygon_data.
I have created a Z-transformation and I call it like this (I also have a separate transformation for all the customizing generated with SAP chart designer but that one works fine):
DATA: data_xml TYPE xstring.
CALL TRANSFORMATION ztest_ce_tables2xml
      SOURCE polygon_data = polygon_data
      RESULT XML data_xml.
Since I am trying to create a scattered chart I need to insert an X and Y value for each coordinate.In the manual SAP Chart engine - XML format description it looks like this:
<ChartData>
<Series>
<Point>
<Value type="x">1</Value>
<Value type="y">1</Value>
</Point>
<Point>
<Value type="x">2</Value>
<Value type="y">2</Value>
</Point>
My ST-program that I cannot get to work looks like below. How can I loop through my internal table and get the X and thy Y value for each row in my internal table?
BR Tommy (Sweden)
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="POLYGON_DATA"/>
<tt:template>
<ChartData>
<Series>
<tt:loop ref=".POLYGON_DATA">
   <Point>
     <Value type="x"><tt:copy ref=".POLYGON_DATA.X_VALUE"/></Value>
     <Value type="y"><tt:copy ref=".POLYGON_DATA.Y_VALUE"/></Value>
   </Point>
   </tt:loop>
</Series>
</ChartData>
</tt:template>
</tt:transform>

Hello again.
I found the solution and would like to share it with the forum, maybe it could help someone.
My first error was in the call transformation statement:
CALL TRANSFORMATION ztest_ce_tables2xml
      SOURCE polygon_data = polygon_data [] <----
Do not forget these
      RESULT XML data_xml.
I also had an error in the ST program, it should look like this:
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="POLYGON_DATA"/>
<tt:template>
<ChartData>
<Series>
<tt:loop ref=".POLYGON_DATA">
   <Point>
     <Value type="x"><tt:value ref="$ref.X_VALUE"/></Value>
     <Value type="y"><tt:value ref="$ref.Y_VALUE"/></Value>
   </Point>
   </tt:loop>
</Series>
</ChartData>
</tt:template>

Rapid Mart for SAP - Sales / List of source tables

Hi,
a customer would like to have a list of the source tables that are read by
the Rapid Mart for SAP - sales (SA).
Has anybody such a list. I can only find information about the target tables.
Regards,
Martin

Before I say this, if a customer wants to know the sourcing, that is intellectual property. If they own the Rapid Mart, then they have rights to the sourcing information. I never just give this information away since it's proprietary, and can be used without a software purchase to assist a prospect.
One approach I use is to install the Rapid Mart into an empty repository, then you can open the source SAP DataStore, and that will be all the source tables references. This will give you the comprehensive list, but as Werner suggested, you need to open each DataFlow and determine it's source table(s) and lookup table(s) to refine your search.

SAP Best Practices for Data Migration :repositories only on MS SQL Server ?

Hi,
I'm implementing the "SAP Best Practices for Data Migration" (see https://websmp109.sap-ag.de/bp-datamigration).
As part of the installation you have to install MS SQL Server Express Edition. The installation guide contains detailed steps to do this. All repositories for Data Services should be running on SQL Server, according to the installation guide.
The customer I'm working for now does not want to use SQL Server, but DB2, as company standard.
So I use DB2 for the local and profiler repositories.
I notice however that the web application http://localhost:8080/MigrationServices does not support DB2.The only database type you can select in the configuration area is MS SQL Server.
Is this a limitation, a by design ?

Hans,
The current release of SAP Best Practices for Data Migration, v1.32, supports only MS SQL Server. The intent when developing the DM content was to quickly set up a temporary, standardized data migration environment, using tools that are available to everyone. SQL Server Express was chosen to host the repositories, because it is easy to set up and can be downloaded for free. Sone users have successfully deployed the content on Oracle XE, but as you have found, the MigrationServices web application works only with SQL Server.
The next release, including the web app, will support SQL Server and Oracle, but not DB2.

Want to know SAP MM Table, like table VBFA for SD Document Flow

Hello Experts,
I want to know, direct relationship between GR against PO line item and IR against PO line item.
I want to know, is there any SAP table for MM which gives direct relationship between succeeding document and preceding document, similar to table VBFA for SD Document Flow.
We have EKBE table which gives information about GRs and IRs for PO Line items.
Consider following case,
We have PO with line item say P1.
Two GRs are done for the same item, say G1 and G2.
Also two IRs are done for the same item, say I1 and I2.
In table, EKBE it just shows that, G1 and G2 are done for P1.
Similarly I1 and I2 are done for P1.
I want the table showing that, I1 is done after G1 and I2 is done after G2.
(or may be showing that, I1 is done for G1 and G2)
Do we have such table in MM? If such table does not exist, is there any way to verify this case?
Please share your opinion.
Thanks in advance.
Amrut

Amrut,
If it is a GR based IR (check PO item Invoice tab- GR Based IV checkbox), you will find this link in table RSEG. You will find the GR number & item number in Reference number & Reference number Item field (LFBNR & LFPOS).
If it is non-GR based IR, then I think only way is to get it through EKBE (which you have explained in your question) since these two are not linked directly.

Gokul

Integration Kit for SAP - Open SQL access to tables. List incomplete.

After we install the BO integration kit for SAP and CR 2008 we were able to connect to SAP and open SAP Data Dictionnary tables (Open SQL access).
I have a problem however:
when I display the list of available tables, the is not showing all the tables in the SAP system. I believe it stops at some point.
I see all tables with low letters or starting with /BIC...
I have custom tables with names ranging from ZR1 to ZR5.
Of these I only see tables up to ZR2*.
My guess is :
either that the table list displayed is limited to a certain mumber of tables
or that there are some authorisations issues to be solved to view all tables (but the same SAP User sees all tables in SE11)
or there is a table related setting in the Data dictionnary that makes some tables visible by CR and other not
Thanks in advance for any answer.
Claudio Ciardelli

correct - it stops at one point because showing you more than 30.000 tables doesn't really help. Right click on your connection (server entry), select the menu options, there is an entry called Table name like. in your case enter Z% and hit F5 for a refresh and you will only get tables shown starting with Z

Data migration for SAP E-Recruiting

Hi all,
We are looking for a standard way to migrate data from a nun sap system into SAP E- Recruiting.
Is there any way for doing so?
Thanks,

Migration of "CRONACLE for SAP solutions" to "SAP CPS for Netweaver"

Hi,
We have standalone Cronacle/CPS 6.02. We are in the process of researching about migrating to "SAP CPS for Netweaver" like SAP CPS M33. We have the following questions.
1)Is a migration path available to migrate from "CRONACLE for SAP solutions" to "SAP CPS for Netweaver" ?.
2)What are the benefits of going to "SAP CPS for Netweaver" ?.
3)Is the migration can be done by ourselves or any SAP migration consultant is required?.
Please advise.
Thanks.
Raj.

Hi Laurence, Raj,
This question is very old and I had not seen it before.
To upgrade from CPS 6.0.2 or 7.0.4 to 8.0.0 (aka M33). I do not know if SAP consultancy offers anything for this, you want to check with them. SAP might refer you to Redwood, though.
As for the differences, where do I start ... ;-)
Actually, CPS 8 is a major platform shift. Version 6 and 7 were PL/SQL-based solutions, version 8 is Java-based. You have many more possibilities built-in, such as better XBP 3.0 support, web services, SAP BusinessObjects, SAP PI/XI control, ... the list could go on forever.
Some older platforms (very, very old) are no longer supported, afaik, but you get native z/OS (mainframe) platform agents, AS/400 agents ... the user interface is platform independent, so you can access it from any OS including, but not limited to, Windows, Unix, Linux, and Mac OS X. There is even an iPhone/iPad client.
BTW, I do not know how long version 6 and 7 are supported.
The platform shift means that you might have to use a PL/SQL API in version 8. I guess it depends on how much PL/SQL you use. If most of your jobs are SAP and OS jobs, you would not even need that.

HP
