When adding an item to a PO (via "Quickscan" entry of a supplier's part # for it), Manager often warns that the supplier doesn't carry that item. I can easily override the warning and add the item.
Why would Manager think this supplier doesn't have the item? It is correctly identifying WHICH item I want via the supplier part # (and a quick check on the item's properties verifies the part number is there).
FYI, this is a supplier with only one entry in my suppler database (not one with multiple locations. Also, the supplier IS identified on the Header of the PO using the lookup function.
Thanks for any help in solving this mystery.
