SAP S/4HANA or ECC

Integration Context

SAP's IDoc and RFC-based document flow requires a certified ASP middleware layer to transform standard billing output into PINT AE-compliant UBL 2.1 XML before submission to the UAE Peppol network. Businesses running ECC on-premise face additional complexity as the Peppol AS4 access point must be decoupled from the core system, typically requiring integration via SAP PI/PO or a dedicated cloud connector provided by the ASP.
