0rt_pa_tran_control initialization of delta queues

Hi all,
we are doing initialization for delta queues of Infopackage 0rt_pa_tran_control (POS DM), but the initialization job finished with the error RSAR 260 "Source system XXXXXXXX is not active for this BI" (XXXXXXXX is the logical system).
Any idea? Thanks

Hi
Please do a source syste check...

Problem with initialization Delta queue

Hi Gurus,
I have problem with initialization of delta queue when I try load transaction data from R3 (FM) to BI.
Error message: Deviation of (64 seconds) between qRFC counter (000012365466830000080000) and actual time (08.03.2009 21:10:19).
I have no idea where is the problem because this problem occurs only in PRD systems. In DEV and QUA system everything is OK.
System BI: BI 7.0
Source system: ECC 6.0
Thank you for all answers!

Hi,
Replicate the DS in BW Prod and then Activate Transfer rules and then try.
First you delete the DElta quae in RSA7 for the particular datasource in the R/3
source system then you try to intialize, here you are trying to intialize datasource with
same selection conditons . thats why it is giving shortdump

Problem to initialize delta queue of datasource from CRM 7.0.

Hi all,
I've some problem to initialize delta queue of datasource from CRM 7.0. After initialize the Init in BW, the delta queue was created but after the user changed data, this changed didn't populated into delta queue.
I tried the steps below but without any success. Anybody know how can I correct this issue?
Suggestion 3: Please check the following.
Please Check if the services have been generated in transaction GNRWB.
If they are not active(not marked 'X' before their names) then activate
the services following the steps here.
Go to transaction GNRWB
Select BUS_TRANS_MSG
Select (on the right, the services) : BWA_DELTA3, BWA_FILL, BWA_queue
Press Generate.
Also check for the following:
1. The delta should have been initialized successfully.
2. Confirm that all Bdocs of type BUS_TRANS_MSG
are processed with success in SMW01.
3. If there are queues in SMQ1 with erroneous status then activate
these queues.
In Transaction SMQ1 if there are Queues existing with
names beginning with CRM_BWAn (n is number) then
activate these queues in the same transaction.
4.a)If required activate the datasource
Go to transaction BWA5 > select the required datasource and
activate.
4 b) The Delta may not be active ,activate the delta in BWA7 by
selecting the name of the datsource and pressing the candle icon for
'activate delta'.
5. In BW system
Go to transaction RSA1 > modeling > infosources > select the
infosource > right mouse click on the selected
infosource > choose option replicate datasource
Activate the infosource.
6. Go to the scheduler for the infosource > select delta in the
update >choose the option PSA only (in the Processing tab)

Hi Peter,
Thank you for your answer.
But we need to find out what the reason for this import error is.
Our customer will not be very pleased to see that all IDocs from CRM system cannot be found in the IDOC folder.
IDX2 import of metadata is no issue.
We were successful for standard and customer Idocs here.
Additional information:
We are already importing Idocs from a SAP ECC 6.0 system into PI in another SWCV
successfully. So this is a CRM system specific issue in our environment.

Issue with delta queue initialization

Hello
I am having a problem with an initialization of the delta queue for a certain extractor. The initialization was successfull, and I can see the extractor in the delta queue maintenance (RSA7) in ECC, but when users are posting transactions in ECC, they are not coming into RSA7.
The extractor is 0CO_OM_WBS_6, so its not standard LO cockpit where we have V3 (background) jobs which have to be triggered.
One more thing, the record which was posted was backdated, ie the date is sometime in the past. But I think the delta queue still picks the records. Can i know how the delta queue funtions based on the time stamp?
Please advise.

Here is the OOS note fro FI Datasources.
OSS 485958:
Symptom
The FI line item delta DataSources can identify new and changed data only to the day because the source tables only contain the CPU date and not the time as time characteristic for the change.
This results in a safety interval of at least one day.
This can cause problems if the batch processing of the period-end closing is still running on the day following the period-end closing and all data of the closed period is to be extracted into BW on this day.
Example:
The fiscal year of the company ends on December 31, 2002.
On January 01, 2003, all data of the closed fiscal year is to be extracted into BW.In this case, the FI line item delta DataSources only extract the data with a safety interval of at least one day.
This is the data that was posted with a CPU date up to December 31, 2002.
However, the batch programs for closing the 2002 fiscal year are still running on January 01, 2003.
The postings created by these programs with a January 01 date for the 2002 fiscal year can therefore only be extracted with delta extraction on January 02, 2003. However, extraction should already be possible on January 01, 2003.
Other terms
FI line item delta DataSources
0FI_AP_4; 0FI_AR_4; 0FI_GL_4
Reason and Prerequisites
This problem is caused by the program design.
Solution
The functions are enhanced as of PI 2002.1, standard version.
Due to a customized setting, it is now possible for the FI line item extractors to read the data up to the current date during the delta runs.
During the next delta run, the data is then read again from the day when the previous extraction was called, up to the current day of the call for the new extraction.This means that the delta extraction of the data always occurs with time intervals overlapping by one day.
The delta calculation by the ODS objects ensures that the repeatedly extracted data does not cause duplicate values in the InfoCube.
Activate the new functions as follows:
1. PI 2001.1 or PI 2001.2:
Implement the new functions with the correction instructions in this note.As of PI 2002.1, these changes are already implemented in the standard version.
1. Start a test run for an FI line item DataSource via transaction RSA3.
2. Two new parameters are now available in the BWOM_SETTINGS table.
3. Parameter BWFIOVERLA (Default _)
Set this parameter to "X" using transaction SE16, to activate the new function of overlapping time intervals.
Caution
The new function also uses a safety interval of one day to determine the To value of the selection, if the time limit set by BWFITIMBOR is not reached.This means that only data up to the day before the extraction was called is selected, if the extraction starts before 02:00:00 (default for BWFITIMBOR).
Correction: Parameter BWFITIMBOR (Format HH:MM:SS, default 020000)
The default value for this parameter is 02:00:00.Do not change this value.
If this time limit is not reached, only data up to the previous day (with BWFIOVERLA = 'X') or the day before this day (with BWFIOVERLA = ' ') is selected.
This logic prevents records with a CPU date of the previous day being contained in the posting when the extraction is executed.
Check any OSS notes for your data source.

How to delete the delta queue in the ECC

Hi everyone!
After I tryed to save a new Infopackage and I have the error :
(Deltas already loaded for request REQU_41Q82WJLR9AZCE9ZMKQLVG3RG init. selection; no 2. init
Message no. RSM1071
Diagnosis
Deltas have already been loaded for the init. selection of request REQU_41Q82WJLR9AZCE9ZMKQLVG3RG. A second initialization is therefore not possible with these selection conditions.
Procedure
If you want to carry out a new initialization, you have to choose selections that do not overlap.
If you want to repeat the init. for the same selection, you have to delete the delta queue in the source system, and restart the delta process.
As the error says - Deltas have already been loaded for the init. selection.
Can you please give me some links/guids which describes how to delete the delta queue in the source system, and restart the delta process.
thank you, Ron

Hi,
Assuming as you need to the reinit for same selections.
in such case you need to delete old init.
how to delete init:
Go to your info pack screen, menu Scheduler--> initialization options for source system--> here you can see the existing init, select init(green) and delete it.
Later you can trigger your init info pack with selections.
Thanks

Issue in loading XML data in BW delta queue

Hello All,
My requirement is to stage small amount of XML data in SAP BW. For doing so, i have followed below steps...
1. Create File data source
2. Define Myself data source using file data source with Function module
3. Initialize load process without no data transfer
4. Using SOAP RFC service, Load xml records in delta queue.
Now in step number 4, i am unable to open the SOAP RFC service using which we can select the xml file.
Any help in this regard will be highly appriciated.
Thanks
Ketan

SOAP/RFC service is already activated. Only problem i am facing is as below.......
1. Created HTML page by copying html snipest
2. On created HTML page, select XML file as an input and URL of SOAP service which is pointing out to the application server
3. When i press "Send recordset" button, HTML page throws "Java script" error and data is not being pushed to BW delta queue....
Please share your ideas to resolve this issue.
Thanks in advance,
Ketan

Does "Init without data transfer" creates delta queues?

Does "Init without data transfer" creates delta queues?

Hi,
Yes, Once initialization successful for particular source system, you can see entry at Delta Queue(RSA7).
Hope it Helps

No records in delta queue for 0CRM_SALES_ACT_1 & 0CRM_COMPLAINTS_I

Hi all,
we are linking a SAP CRM system 4.0 (patch level 10) with BW 7.0. We have initialized the delta extraction and everything was fine. Data was extracted and we can see the delta queue in RSA7 but no records are added. Users are creating new activities and nothing appears in the delta queue. We have other extractors delta capable which are working fine.
The main difference is that these two extractors have been enhanced using the Badi CRM_BWA_MFLOW. When we check the extractor using transaction RSA6, records include the information we add in the Badi.
We think the problem is in CRM because, it does not collect any delta data (queue is always empty). BW is capable to extract when initilitialization. We have tried the early delta initialization and the simple delta initialization.
Any help will be appreciated.
Thank you in advance.
As an extension: we can't see the extractors in the qRFC monitor (trans. SMQ1). We can see there the ones which are working...

Hi again,
we finally solved the problem. The thing was that no BDOCS with type BUS_TRANS_MSG were not being generated when creating or modifying CRM activities. Theses datasources need the BDOCS to work. Transaction SMW3_00 had the flag "Do Not Send" set. We unmarked it and everything seems to work now.

Deleted Delta Queue and setup tables on R/3 side

Hi Gurus,
We are in the process of BW upgrade to NW 2004s. There was some confusion and I deleted the delta Queues in RSA7 (delete button on top) and setup tables too.
Now we have refilled the setup tables but nothing is appearing in RSA7 now.
Do we need to reinstall datasources and then replicate in BW?
Please help.
Regards,
Anil

Hi,
You'll need to initialize the datasources again for anything to show up in RSA7.
Now are the R3 users also locked out on the R3 side ? Are any Master data being converted, created ?
If that's the case and users are doing any transactions on the R3 side, you've basically lost the delta data from when you deleted the delta queues to the time you are going to run the inits. There's no way excpet a full update for you to recover all that data. So if R3 side processing is happening as usual, would suggest you start planning on getting the lost data back into BW post upgrade.
Cheers,
Kedar

Direct Delta, Queued and Unseralized V3

HI
FOR IM datasources, BF and UM, the guide mentions Direct Delta as the preferred selection. How do we decide this?
Also for LO cockpit DS in SD, what selection is chosen?
Thanks
Harie

hi Harie,
take a look oss note 505700 -LBWE: New update methods as of PI 2002.1 and 500426 - BW extraction SD: alternatives to V3 updating
hope this helps.
505700
Symptom
Up to and including PI 2001.2 or PI-A 2001.2, only the "Serialized V3 update" update method was used for all applications of the logistics extract structures Customizing Cockpit. As a result of the new plug-in, three new update methods are now also available for each application.
The "Serialized V3 update" update method is no longer offered as of PI 2003.1 or PI-A 2003.1. Between installing PI 2002.1 or PI-A 2002.1 and installing PI 2003.1 or PI-A 2003.1, you should therefore switch to one of these new methods in all applications offering alternative update methods.
Rather than describing an error, this note helps you make the right selection of update methods for the applications relating to the logistics extract structures Customizing Cockpit.
Read this note carefully and in particular, refer to the essential notes required for some applications when using the new update methods.
You will also find more detailed information on the SAP Service Marketplace at: http://service.sap.com/~sapidb/011000358700005772172002

Other terms
V3 update, V3, serialization, TMCEXUPD
Reason and Prerequisites
New design
Solution
1. Why should I no longer use the "Serialized V3 update" as of PI 2002.1 or PI-A 2002.1?
The following restrictions and problems with the "serialized V3 update" resulted in alternative update methods being provided with the new plug-in and the "serialized V3 update" update method no longer being provided with an offset of 2 plug-in releases.
a) If, in an R/3 System, several users who are logged on in different languages enter documents in an application, the V3 collective run only ever processes the update entries for one language during a process call. Subsequently, a process call is automatically started for the update entries from the documents that were entered in the next language. During the serialized V3 update, only update entries that were generated in direct chronological order and with the same logon language can therefore be processed. If the language in the sequence of the update entries changes, the V3 collective update process is terminated and then restarted with the new language.
For every restart, the VBHDR update table is read sequentially on the database. If the update tables contain a very high number of entries, it may require so much time to process the update data that more new update records are simultaneously generated than the number of records being processed.
b) The serialized V3 update can only guarantee the correct sequence of extraction data in a document if the document has not been changed twice in one second.
c) Furthermore, the serialized V3 update can only ensure that the extraction data of a document is in the correct sequence if the times have been synchronized exactly on all system instances, since the time of the update record (which is determined using the locale time of the application server) is used in sorting the update data.
d) In addition, the serialized V3 update can only ensure that the extraction data of a document is in the correct sequence if an error did not occur beforehand in the U2 update, since the V3 update only processes update data, for which the U2 update is successfully processed.
2. New "direct delta" update method:
With this update mode, extraction data is transferred directly to the BW delta queues every time a document is posted. In this way, each document posted with delta extraction is converted to exactly one LUW in the related BW delta queues.
If you are using this method, there is no need to schedule a job at regular intervals to transfer the data to the BW delta queues. On the other hand, the number of LUWs per DataSource increases significantly in the BW delta queues because the deltas of many documents are not summarized into one LUW in the BW delta queues as was previously the case for the V3 update.
If you are using this update mode, note that you cannot post any documents during delta initialization in an application from the start of the recompilation run in the OLTP until all delta init requests have been successfully updated successfully in BW. Otherwise, data from documents posted in the meantime is irretrievably lost.
The restrictions and problems described in relation to the "Serialized V3 update" do not apply to this update method.
This update method is recommended for the following general criteria:
a) A maximum of 10,000 document changes (creating, changing or deleting documents) are accrued between two delta extractions for the application in question. A (considerably) larger number of LUWs in the BW delta queue can result in terminations during extraction.
b) With a future delta initialization, you can ensure that no documents are posted from the start of the recompilation run in R/3 until all delta-init requests have been successfully posted. This applies particularly if, for example, you want to include more organizational units such as another plant or sales organization in the extraction. Stopping the posting of documents always applies to the entire client.
3. The new "queued delta" update method:
With this update mode, the extraction data for the affected application is compiled in an extraction queue (instead of in the update data) and can be transferred to the BW delta queues by an update collective run, as previously executed during the V3 update.
Up to 10,000 delta extractions of documents to an LUW in the BW delta queues are cumulated in this way per DataSource, depending on the application.
If you use this method, it is also necessary to schedule a job to regularly transfer the data to the BW delta queues ("update collective run"). However, you should note that reports delivered using the logistics extract structures Customizing cockpit are used during this scheduling. There is no point in scheduling with the RSM13005 report for this update method since this report only processes V3 update entries. The simplest way to perform scheduling is via the "Job control" function in the logistics extract structures Customizing Cockpit. We recommend that you schedule the job hourly during normal operation - that is, after successful delta initialization.
In the case of a delta initialization, the document postings of the affected application can be included again after successful execution of the recompilation run in the OLTP, provided that you make sure that the update collective run is not started before all delta Init requests have been successfully updated in the BW.
In the posting-free phase during the recompilation run in OLTP, you should execute the update collective run once (as before) to make sure that there are no old delta extraction data remaining in the extraction queues when you resume posting of documents.
If you want to use the functions of the logistics extract structures Customizing cockpit to make changes to the extract structures of an application (for which you selected this update method), you should make absolutely sure that there is no data in the extraction queue before executing these changes in the affected systems. This applies in particular to the transfer of changes to a production system. You can perform a check when the V3 update is already in use in the respective target system using the RMCSBWCC check report.
In the following cases, the extraction queues should never contain any data:
- Importing an R/3 Support Package
- Performing an R/3 upgrade
- Importing a plug-in Support Packages
- Executing a plug-in upgrade
For an overview of the data of all extraction queues of the logistics extract structures Customizing Cockpit, use transaction LBWQ. You may also obtain this overview via the "Log queue overview" function in the logistics extract structures Customizing cockpit. Only the extraction queues that currently contain extraction data are displayed in this case.
The restrictions and problems described in relation to the "Serialized V3 update" do not apply to this update method.
This update method is recommended for the following general criteria:
a) More than 10,000 document changes (creating, changing or deleting a documents) are performed each day for the application in question.
b) In future delta initializations, you must reduce the posting-free phase to executing the recompilation run in R/3. The document postings should be included again when the delta Init requests are posted in BW. Of course, the conditions described above for the update collective run must be taken into account.
4. The new "unserialized V3 update" update method:
With this update mode, the extraction data of the application in question continues to be written to the update tables using a V3 update module and is retained there until the data is read and processed by a collective update run.
However, unlike the current default values (serialized V3 update), the data is read in the update collective run (without taking the sequence from the update tables into account) and then transferred to the BW delta queues.
The restrictions and problems described in relation to the "Serialized V3 update" do not apply to this update method since serialized data transfer is never the aim of this update method. However, you should note the following limitation of this update method:
The extraction data of a document posting, where update terminations occurred in the V2 update, can only be processed by the V3 update when the V2 update has been successfully posted.
This update method is recommended for the following general criteria:
a) Due to the design of the data targets in BW and for the particular application in question, it is irrelevant whether or not the extraction data is transferred to BW in exactly the same sequence in which the data was generated in R/3.
5. Other essential points to consider:
a) If you want to select a new update method in application 02 (Purchasing), it is IMPERATIVE that you implement note 500736. Otherwise, even if you have selected another update method, the data will still be written to the V3 update. The update data can then no longer be processed using the RMBV302 report.
b) If you want to select a new update method in application 03 (Inventory Management), it is IMPERATIVE that you implement note 486784. Otherwise, even if you have selected another update method, the data will still be written to the V3 update. The update data can then no longer be processed using the RMBWV303 report.
c) If you want to select a new update method in application 04 (Production Planning and Control), it is IMPERATIVE that you implement note 491382. Otherwise, even if you have selected another update method, the data will still be written to the V3 update. The update data can then no longer be processed using the RMBWV304 report.
d) If you want to select a new update method in application 45 (Agency Business), it is IMPERATIVE that you implement note 507357. Otherwise, even if you have selected another update method, the data will still be written to the V3 update. The update data can then no longer be processed using the RMBWV345 report.
e) If you want to change the update method of an application to "queued delta", we urgently recommended that you install the latest qRFC version. In this case, you must refer to note 438015.
f) If you use the new selection function in the logistics extract structures Customizing Cockpit in an application to change from the "Serialized V3" update method to the "direct delta" or "queued delta", you must make sure that there are no pending V3 updates for the applications concerned before importing the relevant correction in all affected systems. To check this, use transaction SA38 to run the RMCSBWCC report with one of the following extract structures in the relevant systems:
    Application 02:   MC02M_0HDR
    Application 03:   MC03BF0
    Application 04:   MC04PE0ARB
    Application 05:   MC05Q00ACT
    Application 08:   MC08TR0FKP
    Application 11:   MC11VA0HDR
    Application 12:   MC12VC0HDR
    Application 13:   MC13VD0HDR
    Application 17:   MC17I00ACT
    Application 18:   MC18I00ACT
    Application 40:   MC40RP0REV
    Application 43:   MC43RK0CAS
    Application 44:   MC44RB0REC
    Application 45:   MC45W_0HDR.
You can switch the update method if this report does return any information on open V3 updates. Of course, you must not post any documents in the affected application after checking with the report and until you import the relevant Customizing request. This procedure applies in particular to importing the relevant Customizing request into a production system.
Otherwise, the pending V3 updates are no longer processed. This processing is still feasible even after you import the Customizing request using the RSM13005 report. However, in this case, you can be sure that the serialization of data in the BW delta queues has not been preserved.
g) Early delta initialization in the logistics extraction:
As of PI 2002.1 and BW Release 3.0B, you can use the early delta initialization to perform the delta initialization for selected DataSources.
Only the DataSources of applications 11, 12 and 13 support this procedure in the logistics extraction for PI 2002.1.
The early delta initialization is used to admit document postings in the OLTP system as early as possible during the initialization procedure. If an early delta initialization InfoPackage was started in BW, data may be written immediately to the delta queue of the central delta management.
When you use the "direct delta" update method in the logistics extraction, you do not have to wait for the successful conclusion of all delta Init requests in order to readmit document postings in the OLTP if you are using an early delta initialization.
When you use the "queued delta" update method, early delta initialization is essentially of no advantage because here, as with conventional initialization procedures, you can readmit document postings after successfully filling the setup tables, provided that you ensure that no data is transferred from the extraction queue to the delta queue, that is, an update collective run is not triggered until all of the delta init requests have been successfully posted.
Regardless of the initialization procedure or update method selected, it is nevertheless necessary to stop any document postings for the affected application during a recompilation run in the OLTP (filling the setup tables).
500426
Symptom
With the BW extraction with the structures of the logistics extract structures customizing cockpit there is only V3 updating as an update method up to plug-in release PI-2001.2.
To make every possible effort to ensure the transfer of document postings to BW in the correct sequence the parameter "SERIAL" was added to the V3 collective update (refer also to note 385099). If this parameter is set at the start of the V3 collective update, the update data is read and processed by the database in the sequence of its creation time.
However, this procedure gives rise to the following major performance problem:
If documents are entered in an application in an R/3 System by several users that are logged on in different languages, the V3 collective run will only ever process the update entries for one language in a process call. A process call is then started automatically for the update entries of the documents which were entered in the next language. Accordingly, during the serialized V3 update only update entries which were generated in direct chronological sequence and with the same logon language can ever be processed. If the language changes in the sequence of the update entries, the V3 collective update process is terminated and restarted with the new language.
During every restart, the update table VBHDR is read sequentially on the database. If there are very many entries in the update tables, this can cause the processing of the update data taking so much time that more new update records are generated simultaneously than are processed.
Furthermore, the serialization is not 100% guaranteed in all scenarios when the V3 update is used, as described also in note 384211.
From plug-in PI 2002.1 the option is offered for the most important applications of the logistics extract structures customizing cockpit of selecting between several alternative update methods.
The serialized V3 update is no longer provided from plug-in PI-2003.1.
The modification provided here enables you to use the new update methods for the applications 11, 12 and 13 as early as from patch 5 of PI 2001.2 or PI-A 2001.2.
The following update methods are offered:
direct delta (update mode A):
With this update mode the extraction data is transferred directly into the BW delta queues with every document posting. Every document posting with delta extraction becomes exactly one LUW in the corresponding BW delta queues.
If you use this method it is therefore no longer necessary to regularly schedule a job to transfer the data to the BW delta queues. Otherwise there will be a substantial increase in the number of LUWs per DataSource in the BW delta queues since, unlike previously, with V3 updating the deltas of many documents are grouped together to form an LUW in the BW delta queues.
Furthermore you should note when using this update mode that during delta initialization in an application, from the start of the recompilation run in the OLTP no document postings may be made until all delta Init requests have been updated successfully in BW. Otherwise data in documents posted in the interim will be irretrievably lost.
queued delta (Update mode B):
With this update mode the extraction data of the affected application is collected in an 'extraction queue' instead of in the update dataand can be transferred via an update collective run into the BW delta queues, as is already the case during V3 updating.
For each DataSource,1000 delta extractions are summarized by documents of the application to form an LUW in the BW delta queues.
If you are using this method it is thus also necessary to regularly schedule a job for transferring the data to the BW delta queues. This scheduling is carried out with the same report which is used when you use the V3 updating (RMBWV311, RMBWV312 or RMBWV313). You are recommended to schedule the job on an hourly basis in normal operation - that is following the successful delta initialization.
In the case of a delta initialization the document postings of the affected application can be included again after the successful execution of the recompilation run in the OLTP (OLI7BW, OLI8BW or OLI9BW) if you ensure that the update collective run is not started before all delta Init requests are updated successfully in BW.
In the posting-free phase during the recompilation run in the OLTP - as previously - the update collective run should be be run once successfully to ensure that there is no old delta extraction data in the extraction queues during the reinsertion of the document posting.
Using transaction SMQ1 and the queue names MCEX11, MCEX12 or MCEX13 you can get an overview of the data in the extraction queues.
unserialized V3 update (update mode C):
With this update mode the extraction data of the affected application is written to the update tables as before with the aid of a V3 update module and kept there until the data is read and processed by an update collective run.
However, unlike the current default values (serialized V3 update), in the update collective run the data is read and transferred to the BW delta queues without taking into account the sequence from the update tables. This is why the performance problem described above does not arise in this case.
This method should only be used if, due to the design of the cubes or ODS objects in the BW system, it does not matter whether the data is transferred to BW in exactly the same sequence in which it was generated in the OLTP System.

Solution
If you already want to use one of the above-described new update methods in the applications 11, 12 or 13 with PI 2001.2 or PI-A 2001.2, you can do this with the corrections given here. However, it is vital that you bear in mind the following points:
1. The corrections described here consist ofa modification which is not included in any PI Support Package. Check whether the described corrections are necessary. When you import a PI Support Package, parts of these corrections may be overwritten. When importing the PI Support Package ensure that you have got all of these corrections (SPAM/SPAU).
2. Only copy these modifications in consultation with SAP logistics extraction development.
3. The corrections presented here should only ever be regarded as an interim solution. The functions are only fully available with PI 2002.1 and PI-A 2002.1. You should also consider the option of upgrading soon to PI 2002.1 or PI-A 2002.1.
Note also that if the update methods of the applications 11, 12 and 13 are changed prematurely, other applications can still only offer the serialized V3 update. The performance problem described above continues to apply to these applications. It should, however, be significantly reduced by the absence of the modules of applications 11, 12 and 13.
4. The corrections described here necessitate the importing of Support Package 5 of PI 2001.2 or PI-A 2001.2. The corrections described here are not possible in a lower plug-in release or Support Package status since the functions of the new update methods are not available.
5. If you want to change the update method of an application to "queued delta", you are strongly recommended to first install the most current qRFC version. Refer to note 438015.
6. If you use the corrections below to change from the update method "Serialized V3" to "Direct delta" or "queued delta" in an application, you must ensure that before the corresponding corrections are imported there are no more open V3 updates for the corresponding applications in all affected systems. To check this, you can execute the report RMCSBWCC in the corresponding systems with transaction SA38 with one of the following extract structures:
    Application 11:   MC11VA0HDR
    Application 12:   MC12VC0HDR
    Application 13:   MC13VD0HDR.
The change is possible if you are not referred to open V3 updates. Of course, no document postings should be made in the affected application after the check with the report until the transfer of the corrections. This procedure applies in particular to the importing of the corrections into a production system.
7. If you are already using the update mode "queued delta" with one of the applications 11, 12 or 13 with the corrections stored here before PI 2002.1 and if you want to make changes to the extract structures in this phase via the cockpit, you should ensure that there is no data in the extraction queues before you execute these changes in the affected systems. In particular this applies to the transportation of changes into a production system. In this case it is not sufficient to execute the check report RMCSBWCC recommended in the cockpit and to eliminate the problem areas specified there.
Below we describe how you can check and ensure this condition.
8. When you import PI 2002.1 the changes made here will always be ineffective and you will get the update method "serialized V3" again as the preset update method.
If you have already changed to a different update method in advance in one of the applications 11, 12 or 13 via the corrections stored here, you must consider the following points during the plug-in upgrade to PI 2002.1 or PI-A 2002.1:
a) Before the upgrade you must ensure that there is no more data in the extraction queues MCEX11, MCEX12 and MCEX13. Otherwise it may no longer be possible to process the data, which may have to be deleted from the queues, due to an extract structure enhancement with the new plug-in. You can do this by starting the collective update report (RMBWV311, RMBWV312 or RMBWV313) and by subsequently checking the extraction queues using transaction SMQ1.
b) After the upgrade you must ensure that before the inclusion of new document postings, the update method of the corresponding application used in advance by the corrections specified here is also set in the cockpit of the logistics extraction (LBWE), and that this setting is transported into all clients of the affected systems.
Note in this context that the corrections specified here change the update method so that it is client-independent. The new functions in the cockpit of the logistics extraction from PI 2002.1 or PI-A 2002.1 then allow the client-specific selection of the update methods.
9. If you want to use the update method "direct delta" in application 11 instead of the serialized V3 update, copy the changes specified in the correction instructions "0120061532 0000373868" given below for the include MCEX11TOP using the ABAP editor (transaction SE38) (these guidelines can be used both for PI 2001.2 and PI-A 2001.2).

Direct Delta, queued , Non-serialized V3 Update

could someone out here help me in understanding the Direct Delta, queued , Non-serialized V3 Update...
i mean a detailed level explanation.... or just in case u have any document then kindly pass it on.... to [email protected]

Hi,
Update Methods,
a.1: (Serialized) V3 Update
b. Direct Delta
c. Queued Delta
d. Un-serialized V3 Update
Direct Delta: With this update mode, the extraction data is transferred with each document posting directly into the BW delta queue. In doing so, each document posting with delta extraction is posted for exactly one LUW in the respective BW delta queues.
Queued Delta: With this update mode, the extraction data is collected for the affected application instead of being collected in an extraction queue, and can be transferred as usual with the V3 update by means of an updating collective run into the BW delta queue. In doing so, up to 10000 delta extractions of documents for an LUW are compressed for each DataSource into the BW delta queue, depending on the application.
Non-serialized V3 Update:With this update mode, the extraction data for the application considered is written as before into the update tables with the help of a V3 update module. They are kept there as long as the data is selected through an updating collective run and are processed. However, in contrast to the current default settings (serialized V3 update), the data in the updating collective run are thereby read without regard to sequence from the update tables and are transferred to the BW delta queue.
Note: Before PI Release 2002.1 the only update method available was V3 Update. As of PI 2002.1 three new update methods are available because the V3 update could lead to inconsistencies under certain circumstances. As of PI 2003.1 the old V3 update will not be supported anymore.
(serialized) V3
Transaction data is collected in the R/3 update tables
Data in the update tables is transferred through a periodic update process to BW Delta queue
Delta loads from BW retrieve the data from this BW Delta queue
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Issues:
Even though it says serialized , Correct sequence of extraction data cannot be guaranteed
V2 Update errors can lead to V3 updates never to be processed
direct delta
Each document posting is directly transferred into the BW delta queue
Each document posting with delta extraction leads to exactly one LUW in the respective BW delta queues
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Pros:
Extraction is independent of V2 update
Less monitoring overhead of update data or extraction queue
Cons:
Not suitable for environments with high number of document changes
Setup and delta initialization have to be executed successfully before document postings are resumed
V1 is more heavily burdened
queued delta
Extraction data is collected for the affected application in an extraction queue
Collective run as usual for transferring data into the BW delta queue
Transaction postings lead to:
1. Records in transaction tables and in extraction queue
2. A periodically scheduled job transfers these postings into the BW delta queue
3. This BW Delta queue is read when a delta load is executed.
Pros:
Extraction is independent of V2 update
Suitable for environments with high number of document changes
Writing to extraction queue is within V1-update: this ensures correct serialization
Downtime is reduced to running the setup
Cons:
V1 is more heavily burdened compared to V3
Administrative overhead of extraction queue
Un-serialized V3
Extraction data for written as before into the update tables with a V3 update module
V3 collective run transfers the data to BW Delta queue
In contrast to serialized V3, the data in the updating collective run is without regard to sequence from the update tables
Transaction postings lead to:
1. Records in transaction tables and in update tables
2. A periodically scheduled job transfers these postings into the BW delta queue
3.This BW Delta queue is read when a delta load is executed.
Issues:
Only suitable for data target design for which correct sequence of changes is not important e.g. Material Movements
V2 update has to be successful
Hope this helps

Initialization of delta is deleted in the infopackage.

Hi Friends,
I have deleted delta initialization in the info package, then re-Initialize the info package without data transfer, then scheduled delta Package and went fine with zero records because I scheduled Delta info package immediately after initialization. Next day on wards, I am getting the error Deltas already loaded for request REQU_46B0AEIZLGGHDHF4EEX5TWBIP init. Selection; no 2. Init and also suggested as follows.
Diagnosis
Deltas have already been loaded for the init. Selection of request REQU_46B0AEIZLGGHDHF4EEX5TWBIP. A second initialization is therefore not possible with these selection conditions.
Procedure
If you want to carry out a new initialization, you have to choose selections that do not overlap.
If you want to repeat the init. For the same selection, you have to delete the delta queue in the source system, and restart the delta process.
Choose the menu entry 'Init. Selections in the Source System' from the Scheduler.
Could anyone please help me how to resolve the issue.
Thanks in advance.
Sam

Hi Sam,
If I understand you correctly,
You have removed your Initialisation by going InfoPackage --> Scheduler --> Initialization Options for Source --> Removed the Request
Then you did Init without Data Transfer
Then you have the option from init withoout Data transfer to Delta in InfoPackage and Loaded the Data.
Check in the Process Chain the InfoPackage you have mentioned in the selections may pointing towards Init load instead of Delta.

Re-initialize of delta's

Hi All,
What is Re-initialization of delta's, why and when do we do Re-initialization and How can we achieve that.
Is it applicable for LIS or LO's extraction process
Thanks & Regards
Lisa

Hi Lisa,
Re-Initialization of DELTA simply means resending an INIT DELTA Request.
To fully explain it, it means, deletion and re-creation of existing DELTA QUEUE (For LO Extractors) or deletion and re-creation of last Extraction Queue using either Calendar Day, Numeric, Timestamp, Change Pointer Queue reference record.
We do this for various reasons: It could be one of these
1.) System Failure or crashes resulting to unrecoverable R/3 source system as well as BW.
2.) Extraction Problems that led to mismatch/unsync DELTA Information between BW and R/3.
3.) Accidental deletion of DELTA Queue in either RSA7 or BW.
We can achive that by simply going to the Info package, delete existing DELTA INIT and Requesting a new INIT DELTA Request.
Yes its applicable to LIS or LO Extraction as well as Generic Delta.
I hope I have helped. If I did, please grant points...

Initialize the delta load

Hi BW Experts,
I have question...
1. There is a ODS01 which feeds many data targets.
2. We created a ODS02 which also will be loaded by this ODS01. The update type would be DELTA.
3. We created a INFOCUBE01 which will be loaded by the ODS02. The update method would be FULL UPDATE.
4. The first time (later on i didnt get this msg) when i went to the infosource for the 8ODS02 and tried to create a infopakge to load the full update of the INFOCUBE01, i got a msg that " THERE IS NO ACTIVE DELTA INITIALIZATION FOR THIS DATASOURCE".
The details of the msg is:
Procedure
You have to initialize the delta load for a DataSource before you are able to load the delta data from it.
If you want to load deltas only for the purposes of testing, or you do not require any initialization data (because you have already uploaded it using a full upload, for example) use an initialization simulation.
This way, only the init. entries you require are made in the control tables of the source system, and a 'dummy' entry appears in the Monitor, setting the load status to green.
No data is in fact loaded, however, and the initialization takes only a few seconds to complete.
Does this mean i have initialize the delta load in the ODS02 or the INFOCUBE01.
How do i do that ?
(I actually did few full loads then i was informed that it would be a delta load from the ODS01 to ODS02,
within the infopkg for ODS02, I selected the Delta update next time, and did start immdtly, then check the monitor, it displays no records)
I'm little confused with this initialization, and in what cases would i do it.
Would you please help...
Thank you,
Tia

1. so, you are saying for the ODS02, do a full load first.
2. Then do a "Initialize delta process".
3. Then do a "delta process".
I had partially tried this, I did a full load first in one infopackage, then created another infopackage trying to do a "Initialize delta process". I get a msg as following:
Diagnosis
Deltas have already been loaded for the init. selection of request REQU_3ZEHH34LV68LVHAWT75TJVIF8. A second initialization is therefore not possible with these selection conditions.
Procedure
If you want to carry out a new initialization, you have to choose selections that do not overlap.
If you want to repeat the init. for the same selection, you have to delete the delta queue in the source system, and restart the delta process.
Choose the menu entry 'Init. Selections in the Source System' from the Scheduler.
Any thoughts...
Thank you,
Tia
