Hi Pradeep
We understand your problem. Please give us the below details
1) In the source DSO, do you see the data mart status like below?
2) Did you try executing the DTP with Delta fetched settings? This is not mandatory in all data flow. But since we are unable to get the exact reason on why the delta load is fetching all requests from the source, you try doing this once.
3) Please share the image of your DTP's extraction tab
Regards
Karthik
