SAP Business Warehouse Question:
What is differences between QUEUE DELTA & DIRECT DELTA?
Answer:
In case of queued delta LUW's r posted to extractor queue
by scheduling V3job we move the documents from Extactor
queue to Delta queue and we extract LUW's from Deltaqueue
to SAP BW by running Delta loadsQueued delta maintains
Extractor log to handle the LUW's which r missed.
In case of Direct delta LUW's r directly posted to Delta
Queue(RSA7)and we extact the LUW's from DeltaQueue to SAP
BW by running Delta loads.It degrades the OLTP performance
becoz when LUW's r directly posted to DeltaQueue the
application is kept waiting until all the enhancement code
is executed.
