Error with Generic delta extractor when checking in RSA3
I have created one Test Generic Datasource based on Table MARA.Delta specific field I mentioned is LAEDA(Last changed On). After creating I have generated the datasorce also. But when I check the datasource in RSA3, I am getting error if Update Mode is "D". Error is "An error occurred during extraction". I am not seeing this datasource in RSA7 (Delta Queue).
If I say Update Mode is "F", then extractor is working fine.It is fetching some records.
Your help will be appreciated.
