Concepts Tasks Settings Invoicing Contents Invoicing Overview Creating Invoices Working With Invoices Viewing Information about Invoices APM invoicing is used to match supplier invoices against the information in the APM procurement system (purchase orders and purchase order lines). The invoicing function allows invoices to be entered, matched, and balanced. Discrepancies are displayed immediately, and a user can make the necessary corrections or forward the invoice to the appropriate person to act on. The topics in this section explain how to create invoices and invoice lines, balance and approve invoices, work with invoice batches, create credit notes, and use evaluated receipt settlement.
