Generic delta with RSVD_BW_GET_DELTA_DATA
I am creating a generic datasource with delta using the copy of the function module RSVD_BW_GET_DELTA_DATA.
My function module has the logic to get delta records based on CPUDT.But when i run the extractor from rsa3 using delta or init mode the update mode is always 'F' ( full ).
when i debugged it i see that it is going to the function module RSC1_INIT_BIW_GET even before it goes to my function module where in the update mode is getting filled as 'F' all the time.
Is there a way to solve this. Please help as i have been struggling with it. I had tried the copy of RSAX_BIW_GET_DATA_SIMPLE, again with the code to handle delta but it also was behaving the same way: taking the update mode as full all the time.
Any help is greatly appreciated
