SAP Integration Suite handles integration. It connects SAP S/4HANA Cloud Public Edition to other SAP and non-SAP applications, in the cloud and on-premises, and to business partners. It supports several integration styles.
| Integration style | Use |
|---|
| Application programming interfaces (APIs) | Direct request-and-response |
| Business events | Systems that react in near real time |
| Business-to-business (B2B) flows | Partner exchange |
A library of prebuilt connectors means common connections do not start from scratch. Data flows where it is needed, governed and monitored, instead of through brittle point-to-point links.
Extend without touching the core
Where standard functionality leaves a genuine gap, the platform extends the ERP in the way that fits. Business experts adapt applications with low-code and no-code tools. Developers add custom logic in an upgrade-stable way with SAP Extension Suite and SAP Business Application Studio. Larger needs become side-by-side applications running on the platform. Each route follows the Clean Core principle. The extension stays on released interfaces and outside the standardized core, so upgrades stay routine.
