Delta capturing methods -num pointer,calday,timestamp....

Question

hi experts
while discussion with seniors ,I got one question which was like...
Normally in Generic Extraction for Transaction Data...we capture delta by NUMERIC POINTER or TIME STAMP or CALENDAR DAY....Is there any other way to capture delta....?Are there any tables which capture deltas?
Incase of Generic Extractionfor Master Data ....is there any other way to capture deltas other than NUM POINTER or CAL DAY or TIME STAMP..?How do you do it step-by-step?which tables capture delta in this case?
Thanks and Regards

Hello,
If your datasource is created based on a view you can use the generic delta - RSO2 - Generic Delta.
(there you can see the options)
If your datasource is based on a function module, you can not use this option - it will not work. In the function module you have to deal your delta in the FM code.
Create a copy after the Function Module RSAX_BIW_GET_DATA_SIMPLE and in this code try to deal the delta.
There is this table: ROOSGENDLM, that is showing you if you have an init and all the deltas. (time stamp). you can use this table.
Please see the links below. Are very usefull:
To create the FM simple (full) use:

For the delta managing in the code, use this link
