SAP tends to hold the books and the materials, but it never works alone. Our link between SAP and everything else is SAP Integration Suite or the integration platform you already run, built on released APIs, business events and well-documented file exchanges. The client-facing layer, the subsidiaries, the data platform and Government services, e-invoicing over Peppol included, all get the data they need, without dozens of one-to-one connections.
If your interfaces still run on SAP Process Orchestration, note that its current release also loses mainstream maintenance at the end of 2027. The S/4HANA plan should therefore cover the interface migration too, and our integrations and API team plans both as one piece of work.
