Vendor Agreement and/or Payment Terms Cannot be Combined

We haven't experienced that particular issue but we've had other issues where out of the blue we couldn't do something we could do the day before and then it magically fixed itself hours or days later. Our latest one was that we couldn't modify any PO line source information like adding something to the deliver to field. We would get an error stating "Cannot add source information other than PO". Twice I opened a case with support only to see the system fix itself before we could schedule a web-ex session. A ghost in the machine. So now when someone tells me they can't do something I'll investigate it but wait a day or two (if it's not keeping everyone from doing their job) if I need to open a case. Not any help to you but at least you're not alone.

Thanks for the quick response, definitely seems like a ghost in the system occaisionally. Usually it seems like a CM ghost, but in this case, I do not think it was the culprit.

We just recently was asked to add the payterms to our vendor agreements in PO25 and now our purchasing group is now having this same issue. If they need to add an item to the po they get this error Vendor agreement payment terms can't be combined. Our only workaround is to remove the pay terms temporarily to allow them to add the line and release the po and then we set the pay terms back. Does anyone know how to fix this issue so we don't have to contstantly remove the terms and set back? Thanks
