In ApprovalMax, a Bill can be matched to a Purchase Order only if the supplier on the Bill matches the supplier on the Purchase Order. If the supplier names differ, the system will not allow the Bill to be matched to the Purchase Order.
If the supplier on a Bill differs from the supplier on a Purchase Order, you can edit the supplier information on either document to ensure the supplier names match.
Once the supplier names are identical, try matching the Bill to the Purchase Order again.
