Hey Suraj Tatpalliwar,
thanks for your reply. We have already tried everything, i guess. May be you can tell me more details about this special note (keyword for the search or a link).
We checked some notes from the market place, but all of these checked notes are not for our problem. Ether its not the same kind of problem or the system patch level of the note is under our release (we have the highest release now). Perhaps we are now so desperate that we dont see the wood for the trees :-(.
The Problem is finally that the system all the time try to insert the quant in the table with an existing quant (guid-number). At the first time its the right way, but in the second, they should delete the quant from the receiving zone and update the existing quant. But the all the time they insert quants.
Best regards
