By default, Ariba Buyer will only display purchase orders from the same supplier as the invoice. If there is no supplier on the invoice, the list includes all purchase orders based on the user's permissions.

You can also unmatch the invoice from a purchase order it was previously matched to.

• Select a purchase order to match to the invoice:
  • Click Select to choose a purchase order or to unmatch the currently matched purchase order. If you are in the process of matching an Invoice Reconciliation (IR) document at the header level, you return to the Invoice Reconciliation screen. If you are in the process of matching an IR document at the line item level, you return to the Manual Match - Order Line Item screen.
  • To search Ariba Buyer for another purchase order, enter a purchase order number in the Order ID field and click Search.
• Click Cancel to return to the previous screen.
