This is my first project in BW. Please help!! The existing function module using 3 tables to extract (Full update) data. Now, I have to enable the delta for this generic extractor. I have seen RSA3_GET_DATA_SIMPLE (nothing specified for Delta) and RSVD_BW_GET_DELTA_DATA function module to make use of it using OPEN CURSOR but in that fm I can see only one table being used.
Should I use 3 cursors to extract if so how should I join them? Can anyone please help me how to use cursors joining 3 tables and extract right delta data?
This would be a greatest help!! Thanks in advance.
