Applying partial credit
Use partial credit when you need to credit only part of an invoice amount that was matched to a purchase order. Partial credit reduces the vendor’s balance without changing the PO, its quantities, or matched amounts. Partial credits are applied on a credit memo by selecting eligible non-inventory PO lines and entering a credit amount that is less than or equal to the remaining balance.
For example, a vendor sends an invoice for $100 matched to a PO line. Later, the vendor agrees to refund $20 due to an overcharge, but the PO itself is still valid and should not be changed. You must create a credit memo and apply $20 in partial credit on the PO line. The vendor balance is reduced by $20, and the PO and its matched amounts are unchanged.
Note: Before you run this procedure, you must successfully match an invoice. You cannot use partial credits on PO lines that already have cost or quantity adjustments.
