For a generic function module based datasource..we can enable the delta capability by say for example based on date , time..or any changing parameter..
say suppose AEDAT (last changed by).. I can enable delta by this AEDAT field..
now my question is how are new reocrds recognised..??
I guess..even new record that is created...say for example will have creation date as well the last changed by as same date for the first time and SAPI (Service API ) recognises by AEDAT.. for new records as well.
Let me know my reasoning is right or not..
