Hello
I know it has been a while, but can you explain what you found exactly ?
I have the same error and what I have noticed is that when I created the Sales Order from a Quotation the field AcctAssgGr (table VBKD - field KTGRD ) is blank ! If I fill it manually then the check is ok.
is there some "bug" in creation Sales Order with reference ? Am I missing something ?
thank you in advance
