We are using Baan IVc4.

How can I find the PO(s) which is being matched by a specific Purchase Invoice ?
which session code:
Note: We are practice using one Purchase Invoice to match multiple Purchase Orders.

Please advice.

You should be able to use Print Matched Purchase Invoices With Receipts. The standard menu path is Finance/Accounts Payable/Transaction Processing/Reports.

The session code is tfacp1431m000.
