Delta for custom datasource not working
I've created one FM (using RSAX_BIW_GET_DATA_SIMPLE) which is working fine. The delta field I'm using is timestamp.
Based on this FM, I created a custom datasource which is also working fine in RSA3. I initialized this datasource which brought required data into BW.
The issue is when I change few records in source system, the extractors works fine and brings delta records in RSA3, but when I trigger delta load in BW it brings 0 records??
I've left upper and lower safety intervals as blank, could this be the issue? But it works in RSA3 even if they are left blank.
