APD doesnot load data to DSO

Hi

I created one simple query with one charcateristic infoobject on same infoobject (purpose is to provide master data)...I created one direct update DSO with single key field(same infoobject used in query) and tried to load DSO from query with APD...Its not showing any errors but loading 0 records to DSO...Any ideas where the error is happening?

Thanks
