To complete the matching process successfully, you must match the full amount of the invoice to the receiver amounts.

For standard invoices, the invoice postings are generated and the sub-ledger updated when the invoice is saved. For this reason, you cannot adjust the invoice amount when matching, but instead must account for any difference between receivers and invoice by adjusting the matched amount to equal the invoice amount, using manual posting if necessary. This flow is described in Matching Standard Invoices to Receivers.

The alternative to matching receivers against posted invoices is to perform the invoicing and matching in one process, and determine the final invoice amount and final postings once the matching is complete. You can use supplier initial invoices to synchronize the process in this way. Supplier initial invoices are saved without postings. The initial invoice can be created, linked to PO numbers, and matched in one movement, and the invoice total can be adjusted to equal the matched amount before matching is completed. This flow is described in Matching Initial Invoices to Receivers.

Tax, SI, and Matching postings are generated at different stages of the matching flow for standard and initial invoices, as illustrated in Standard and Initial Invoice Postings.

You can only match invoices and receivers that have been created within the same domain, and can only include purchase orders in a matching process that have the same currency as the supplier invoice.

You can match receivers with invoices that have been generated for different suppliers, with the following restrictions:
