## Procedure

1. Navigate to Accounts Payable OperationsAccounts Payable Workspace.
2. Select the list icon (![List icon]()).
3. Navigate to ListsInvoicesAll open invoices.
4. Open a PO Invoice.
5. Under Summary Details, in the Purchase order field, search for and select a purchase order.  
   The following confirmation message is displayed: Updating the Purchase order may require PO mapping again. Do you want to continue?
6. Select OK.  
   The confirmation message is not displayed if you update the purchase order on a PO invoice that is in the Draft, Received, or Accepted status.

   The confirmation message is displayed if you update the purchase order on a PO invoice either before or after PO mapping is completed. If you select OK after you change the purchase order in the
   Purchase order field, the invoice lines are mapped with the purchase order lines of the newly associated purchase order. Subsequently, the automated PO mapping process is run and the
   invoice status moves to PO mapping error or PO mapping completed.
