Deleting Delta Queue?

Dear Friends,
Due to some problems with the initial loads in Inventory (2LIS_03_BF), i deleted the delta queue in R/3 and also deleted the data in the cubes. No i want to do a initial load again in BW for Inventory.
Will there be any loss of data or any other problems since the set jobs in R/3 were done on 6/10/2006 and since then i have run inits for the same.
Thanks
Raj

Sat,
In R/3 the setup tables were filled on 6/10/2006 with the users locked out. Since then i was trying to run init load in BW but was not successful. Now i emptied the cubes and i am running a init load again in BW. Do you see any problems? i think in BW the users dont need to be locked out during an init load. Am i right? Please give your thoughts.
Thanks
Raj

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.

How to delete the data in update queue and delta queue for Queued delta?

Dear BWers,
How do i delete the delta queue and update queue data before i fill the setup tables for a extraction based on Queued delta. Please help.

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

ABR complete delta with deletion flag via delta queue (cube compartible)

Hello
DS 2LIS_04_P_COMP is delta enabled with ABR complete delta with deletion flag via delta queue (cube compartible)
Is it possible to use this type of delta for ods? If yes , what kind of changes are required
Thanks

Hi
ABR means
A - After Image
B - Before Image
R - Reverse Image
Since updating DSO is usually in overwrite mode it requires After Image.
So u can use the data source with ABR delta to load into DSO (ODS).
Cheers.

Is there any solution to Delete Single Record in Delta Queue 2LIS_08TRFKZ

Hi,
Is there any solution to Delete the Single Record in Delta Queue at R/3 -(RSA7) for Datasoure 2LIS_08TRFKZ
A wrong posting has been posted at R/3, its has been deleted once they came to know its wrong at R/3.
Now the Problem is wrong data has come into Delta Queue RSA7.
We are unable to extract the data in BW. Its not even coming till PSA also so that we can delete at PSA itself that particular record.
Is there any solution to delete the Single Record in Delta Queue at R/3 -RSA

Sorry I didnot see this error before.
I guess you didnot try error handling hence you get this error BW side.Try error handling first.
If this doesn't work then you can go with above method.

Issue with extraction of data to Delta Queue

Hi All,
Background:- One LO Data source each from Application 8, 11 and 12 was active in LBWE. Update method was specified as Queued Delta. However this Data source was not utilized to pull any data to any of the Global BI Systems. These data sources did not exist in RSA7. There was a business requirement that these Data sources were to be enhanced, along with this other Data sources under these applications were also required to be enhanced. There were entries in LBWQ which used to get dumped out at regular interval by running the SAP Standard Collector jobs. Since no Delta was initialized for these extractors, no entries were passed on to RSA7.
Problem:- We did not clear the entries or took a downtime before sending transports and now the collector job is dumping saying the structures have changed, which is correct. I believe we wonu2019t require any data sitting in LBWQ as none of the extractors had any entry in RSA7. This problem is happening only in our Production system and we did not face this problem in any other system even though there were entries existing in LBWQ.
What is the solution to fix this? Is the only option now is to delete the Queue from LBWQ and then run the collector job or is there any other way and will that fix the problem?

Hi Victor,
As u said that u were not using the DS for Application 8,11 and 12.. in this case I believe that u dont have any data in BW as well(Historical data). As u have enhanced these data sources with the new requirement, I hope u must have changed the structures in BW side as well to load the data to the newly added fields.
So in ur case u need to replicate the DS in BW and then activate the Transfer structure for all of them.
And then flushout the LBWQ for all those 3 applications and then take the setup tables fill for the same (but this requires the down time in prod to make sure that u wont loose any records).
Before setup check SM13 whether u have any blocked entries for all these entries if so then u can delete them as well before taking the setup.
Once the setup is done then u can take Init without data transfer and then take repair full loads in BW for the targets.(Activate ur V3 once the init- without data transfer took place for the regular deltas) .
Thanks

R/3 Patch Upgrde Problem due BW Delta Queue.

Hi Expert,
I have extracted all the logistic & delta data in BW to make delta queue emplty. My query is that ,should it delete these queue in RSA7 or it should disappear after extraction.
In LBWQ there are only two entry MCEX17 & MCEX17_1 , these queue are still there after extraction.what to do these queue ?
These queues are giving error while upgrading patch.

Hello Anand ,
There is no need to delete the queues for the upgrade, you only need to make sure that there is no data in these queues in rsa7 that need to be extracted, if you run the relevant infopackage twice on the BW side then it should clear the data from RSA7 , before doing this please make sure that all data has been updated from lbwq to rsa7 (if using queued delta) and that there is no data in sm13 for the queues. In RSA7 you can double click on the Individual queues and if you check under delta and delta repeat option for these logistics queues you should find 0 records.

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

Issue with Delta Queue

Dear All,
We have scheduled Delta Q on developement and it was working fine.
But on Quality side all the jobs for Application 11 are failing while application 13 are running successfully.
Please help on the same immediately.
Regards,
Sohil Shah.

Hi Sohil,
It seems that you have changed the structure of the datasource. When you change the structure of the datasource you have to make sure that there is no data in the delta queue or SMQ1 queue of the target system before you transport it. Delete the data from the delta queue and SMQ1 queue and reintialise the datasource.
Let me know if you have any doubt.

Sequence of operations - Direct Delta, Queued Delta, Unserialized V3 Update

Is the below understanding about each update method correct?
a) Direct Delta
- The user selects a process (e.g. creating, updating or deleting a purchase order), fills the fields in the screen, presses SAVE.
- A module makes inserts, updates and deletes on the Application Tables.
- This or another module inserts delta relevant information (e.g.: before and after image, the key for deletion, reverse image, etc) about this PO in the Communication Structures.
- Another module reads the Comm Structures and inserts this information in the Delta Queue.
- COMMIT the operations in the App Tables and in the Delta Queue.
- The user receives a success message.
b) Queued Delta
- The user selects a process, fills the fields in the screen, presses SAVE.
- A module makes inserts, updates and deletes on the App Tables.
- This or another module inserts delta relevant information about this PO in the Comm Structures.
- Another module reads the Comm Structures and inserts this information in the Extraction Queue.
- COMMIT the operations in the App Tables and in the Extraction Queue.
- The user receives a success message.
- Periodically, a Collective Run inserts this information in the Delta Queue and deletes it from the Extraction Queue.
c) Unserialized V3 Update
- The user selects a process, fills the fields in the screen, presses SAVE.
- A module makes inserts, updates and deletes on the App Tables.
- COMMIT the operations in the App Tables.
- The user receives a success message.
- This or another module inserts delta relevant information about this PO in the Comm Structures.
- Another module reads the Comm Structures and inserts this information in the Information Structures (also known as Statistical Tables), as part of the LIS data flow u2013 as I understand it has nothing to do with LO data extraction, but it is coded this way.
- If the inserts into the Information Structures work well, another module reads the Comm Structures and inserts this information in the Update Table.
- Periodically, a Collective Run inserts this information in the Delta Queue and deletes it from the Update Table.

Thanks for your attention, but I've already read:
- Roberto Negrou2019s blogs,
- OSS Note 505700,
- Power point u201CNew Update Methods for Logistics Extraction with PI 2003.1u201D (quoted in the OSS Note, link u201Chttp://service.sap.com/~sapidb/011000358700005772172002u201D),
- many threads wich provided very useful information.
I need now more detailed information, step by step operation on each update method, like I posted in the thread.
Actually I want to cross this information with another thread I posted (), about Figure 6 (Comparison among call function hierarchies involved in different update methods).
This Figure is showed in Negrou2019s Episode Three and in the power point. I believe that this figure is wrong or at least is missing something.
Do you know about these two points, or can you please forward to someone who can help us ???

Question about Note 886102 - Empty the delta queue of the connected SAP source systems

Dear expert
I'm doing the system refresh from ECC PRD to QAS using the hot backup of PRD
Before i start the database restore i was told to do the following step since this ECC has connection with one BW system
-----------------------Step -----------------------------
2.17 SAP note 886102 scenario C3
Empty the delta queue for all of the connected BW systems.
Execute all delta info packages two times on BW side, to clean up the delta queue in the source system. This is needed, because BDLS cannot rename the still available LUW-s in the qRFC queue.
----------------------Step-----------------------
But unfortunately i missed to execute this step
And the Q11 is now retoreing the backup of the database
My quesion
1. what will be bad consequence due to not execute this step? any way to makeup this error?
Best regards,

Hi Kate,
The probably issue which I could forsee is data getting wrongly updated into production if RFC connection from ECC to BW is not stopped.
Solution here could be to disable or deletethe RFC connections between ECC and BW before starting the SAP system at database level.
delete from sapr3.rfcdes where rfcdest = '<name>';
Once the system is up and running you can recreate them if required.
Also before starting SAP set the number of batch processes to 0 on the profile at OS level so that any released jobs don't start as soon as SAP is up.
Once the SAP system is up execute BDLS and change the logical system name.
Hope this helps.

Deepak Kori

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
Or:

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.

Red Traffic Light for Datasources Delta Queues

Hi all,
Our R/3 source system is connected to our BW system.
Between the two systems we operated standard logistics datasources delta queues, by filling the setup tables and performing an initial update.
The datasources delta queues were created and used over a month (according to the RSA7 they all marked with green traffic light).
Now, we copied the R/3 source system to a new one.
After doing so, all the delta queues traffic light turned to be red.
Does anyone can provide a technical explanation/reason to this problem?
Also, is there something we could do to "save" this delta queue, without needed to delete it and create it all over again?
Thanks ahead,
Shani Bashkin

Hi Eddo,
Thanks for your help.
Yes, I'm using the same system name and system id. The new copied system has the same name and id like the productive system.
Also, it seems like the RFC connection to the BW is lost.
The question is why?
Thanks,
Shani Bashkin

Delta queue analysis for actions pre/post patching

Hi,
We are going to patch both R/3 as well as BW. So can you pls advice me any precautions we need to take for the delta queues??
regards,
Jacob

Dear Raghavendra,
Deleting the init request in BW will delete the delta queue in RSA7.
Q. Is it very necessary..
Is it BW upgrade or r/3 upgrade?
No, this is only the hardware migration. BW and R/3 will be same as it is.
Thank you for the quick response,
thanks,
Sanjana.
