i create a generic data source and try to load delta. The delta based on a calenderdate (change date). After the initial load was run, the data were correct in PSA table. If I start the DELTA run at the same day, 0 datasets were selected (that was correct). The DELTA Queue in RSA7 shows one the right date and delivers 0 sets. When I try to load the DELTA the next day, I would expect the DELTA SETS. But the extractor delivers the hole DATA SETS from the generic extractor again and no DELTA.
Could it be, that I have the wrong KEY FIELDS in my DataBaseTable (Extractstructure)?!?!
Could anybody help?
