Integration overview
SAP integration connects SAP systems to each other and to non-SAP applications, through middleware and protocols, so data and processes flow across the enterprise. This hub maps SAP’s integration technologies old and new.
Match the technology to the need: synchronous APIs (OData/SOAP) for real-time, IDoc/ALE for robust async document exchange, events (Event Mesh) for decoupled notifications, and Integration Suite/PI-PO as the middleware orchestrating and transforming between systems.

- SAP Integration Suite (cloud): the strategic iPaaS (includes Cloud Integration/CPI, API Management, more).
- SAP PI/PO (on-premise): the classic middleware, being succeeded by Integration Suite.
- Watch out: Wrong integration style (sync vs async) for the need.
The integration landscape
- SAP Integration Suite (cloud): the strategic iPaaS (includes Cloud Integration/CPI, API Management, more).
- SAP PI/PO (on-premise): the classic middleware, being succeeded by Integration Suite.
- IDoc/ALE & RFC/BAPI: classic SAP-to-SAP mechanisms.
- OData/REST & SOAP: service-based integration.
- Event-driven (Event Mesh): asynchronous events.
On-premise to cloud shift
Integration is shifting from on-premise middleware (PI/PO) to the cloud SAP Integration Suite, aligning with cloud ERP and hybrid landscapes. New integrations increasingly use Cloud Integration (CPI) and API Management, while classic IDoc/RFC remains important for existing SAP-to-SAP flows.
Choosing an approach
Match the technology to the need: synchronous APIs (OData/SOAP) for real-time, IDoc/ALE for robust async document exchange, events (Event Mesh) for decoupled notifications, and Integration Suite/PI-PO as the middleware orchestrating and transforming between systems.
Common pitfalls
- Wrong integration style (sync vs async) for the need.
- Point-to-point sprawl instead of using middleware.
- Ignoring the cloud direction (Integration Suite).
