without using eInvoice, what is the best way to match an invoice to a PO in IFS? We've been using the receipts screen to make sure we have a proper match before inputting in IFS so that it doesn't stay in "unbalanced" state. Some invoices might be waiting for arrival, but many have been received but the value is too high or insufficient, making things very challenging for proper match.

Is it better to match to the header or match to the line item for all suppliers?

Any help is greatly appreciated.
