Reversing PO Invoices

You can reverse a Purchase Order invoice if the match is complete and the invoice was posted or paid. PO Invoice Cancel (MA75.1) lets you create a credit memo to offset the invoice that was paid in error. You can then create a new invoice to be matched to the receipt to correct the problem.

After the invoice has been reversed, you cannot change the invoice later by using Invoice Cancel (AP30.4) or by using Distribution Adjustments (AP30.2). Similarly, the invoice and the reversal cannot be unmatched.

To unmatch and reverse a PO invoice

  1. Access PO Invoice Cancel (MA75.1).
  2. Select the Purchase Order invoice number that you want to reverse.

    Information about the invoice displays, including the Purchase Order number, invoice date and amount, and related invoices.

  3. Select the Reverse Match form action to reverse the invoice (create a credit memo to offset the paid invoice).

    This step releases the purchase order and receipt for the amount of the reversal (the receipt is unmatched). The reversal invoice is given a suffix of 999. (The entire invoice must be reversed.)

  4. Create a new invoice to be matched to the receipt. For information, see

Follow-up Tasks

  • After the Purchase Order invoice has been reversed, you must run Invoice Distribution Closing (AP175) in order to complete the distributions (for information, see the Accounts Payable User Guide).
