This document defines the standard approach for designing the E-Invoicing solution within the Source-to-Pay (S2P) area. It outlines the end-to-end process for handling vendor invoices and accounts payable (AP) outbound self-billing.

The solution leverages EDICOM as the interface to receive invoices from the e-invoice portals. These invoices will then be routed to the relevant S/4HANA instance via Cloud Platform Integration.

The scope of this document includes:

• Inbound Vendor Invoices – Handling and processing invoices received from suppliers.

• AP Outbound Self-Billing – Processing self-billed invoices in compliance with legal requirements.

• Invoice Cancellation Logic – Detailing country-specific legal requirements. For countries where invoice rejection is restricted, cancellations will be managed through credit notes.
