Why SAP BTP is becoming the integration layer of SAP landscapes
Most SAP landscapes I have worked in share the same history: point-to-point interfaces, custom RFCs and file transfers that grew over the years. Each of them works on its own. Together they make every change expensive and every S/4HANA upgrade harder.
SAP BTP addresses this on three levels.
1. One integration layer
SAP Integration Suite combines Cloud Integration, API Management and event-based messaging. Interfaces are modelled, monitored and versioned in one place. For hybrid landscapes, Edge Integration Cell runs the same integration content on premise.
2. Clean core
When extensions and integrations run on BTP and use released APIs and events of S/4HANA, the ERP core stays close to the standard. Upgrades can be planned like regular releases.
3. A clear migration path
SAP Process Orchestration reaches the end of mainstream maintenance at the end of 2027. Teams that move their interfaces to Integration Suite now can use the migration tooling and fix weak spots on the way.
A newer reason: AI tools
AI agents and tools based on the Model Context Protocol (MCP) need governed access to business data. The APIs, authorisation (XSUAA, SAP Cloud Identity Services) and monitoring that BTP provides for classic integration give these tools a controlled entry point to SAP data.
Conclusion
Integration on SAP BTP is an architecture decision. It means fewer direct connections, released interfaces and one place to see what flows where.
