@MoiraGoggin Sorry, I disagree. The correction cannot occur when the PO is placed, the order is already sitting on the dock waiting to be received into Sage. If you let receivers add the items that were not ordered, it could get buried in the paperwork, possibly paid by AP and the Vendor error will never surface. If something was not ordered on the PO, it should not be received. There should be a process for dealing with such errors but not allowed into IM. It could cause all kinds of problems with history, future material requirements, stock levels, etc
