BW Delta Queue
Hi sap gurus,
We know that there is a bw delta queue in r/3 and also in bw, and the data gets in bw delta queue from where data is picked up by bw requests. What i actually want to know is from where does the data is picked from, is it from r/3 bw delta queue or from bw side bw delta queue. Please clear my doubt. Thank you.

The delta queue is used from the system that delivers the data. If you extract data from R/3, the R/3 delta queue is used.
The concept of the delta queue is that the system that creates/changes records makes a copy of this record into the deltaqueue. Once the BW requests the data for extraction, it looks at the delta queue, retreieves the data and empties the delta queue.
