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:
Incoming E-Invoices from Suppliers– Handling and processing invoices received from suppliers
Invoice Cancellation Logic – Detailing country-specific legal requirements. For countries where invoice rejection is restricted, cancellations will be managed through credit notes.
- AP Outbound Self-Billing – Processing self-billed invoices in compliance with legal requirements.
High Level Design:
Processing Logic of Incoming E-Invoices from Suppliers:
Step1: Suppliers will submit their invoices through the designated e-invoicing portal in accordance with the legal requirements of their respective countries. For instance, suppliers in Italy will register invoices via the SDI platform, while those in Belgium will use the Peppol Network, and so on.
Step2: EDIWIN will capture Syensqo supplier invoices from the designated e-invoicing portals of each country.
Step3: The SAP CPI (Cloud Platform Integration) system will act as middleware between the EDIWIN tool by EDICOM and S/4 VIM, responsible for routing incoming e-invoices to the correct S/4 instance. Invoices will be directed to the appropriate S/4HANA VIM instance based on the buyer’s country.
