Documentation
Definition
If a multi queue procedure is used in an application, document data is transferred into various extraction queues during the delta extraction. When the collective update is started, these are processed with parallel processes and transferred into the BW delta queues.
In installations with a very high document turnover, multi queue procedures optimize the processing time for extraction queues.
In applications that have one or more multi queue procedures, these are defined in a way that means extraction data is always updated into the same queue when creating, changing or deleting the very same document. This guarantees that the data from the extraction of this document is always received into the BW in the same order as it was generated in the OLTP system.
On the other hand, when using a multi queue procedure in BW, the delta order cannot be guaranteed for ALL documents belonging to the application. This is because two different documents can sometimes be transferred into different extraction queues. These are usually transferred into the BW delta queues independently of each other.
Example of a multi queue procedure:
If the multi queue procedure "A" (document number 1-6) is selected in applicattion 12, and deltas are posted for the documents
gen 0080023456 ans 0180045678, entries appear in the following two queues as a result of these postings:
Documt Extraction Queue
0080023456 MCEX12_0080002
0180045678 MCEX12_0180004
In PI 2002.1, the multi queue procedure is only available for applications 11, 12 and 13.
