The process for matching to receipts, is the same as matching to purchase orders; however, to match to receipt, ensure the following prerequisites are complete:
Invoice Match Option for the purchase order shipment is set to Receipt.
A purchase order for the same supplier and currency as the invoice you are entering is approved and open, and has at least one receipt entered against it.
If the Invoice Match option for the supplier site is set to receipt then the match button will default to Receipt and you can use the Match to Receipt window to match receipts to invoices.
You can also match to purchase orders in the Lines tab of the Invoice Workbench. Enter a PO Number and a Receipt number to match to a receipt line.
Payables automatically creates distributions for the matched to receipt lines.
