Why Integration Suite matters for 2027
SAP PI and SAP PO are the integration backbone of most ECC landscapes — connecting SAP to CRM, billing, HR, third-party logistics, banking, and regulatory platforms. Both lose mainstream maintenance in 2027 on the same schedule as ECC. These integrations must be rebuilt or migrated to SAP Integration Suite on BTP as part of the transformation, not as an afterthought. IOTEK includes the integration landscape assessment and Integration Suite migration plan in every S/4HANA & RISE Readiness Sprint.
What Integration Suite delivers
- Cloud Integration (iFlows): message-based integration connecting SAP and non-SAP systems; 2,000+ pre-built integration packages in the SAP Business Accelerator Hub
- API Management: full API gateway — creating, publishing, securing APIs with OAuth, rate limiting, and a developer portal
- Event Mesh: enterprise messaging for event-driven architectures — business events from S/4HANA published to queues, consumed by downstream apps and agents in real time
- Open Connectors: pre-built connectors to 170+ non-SAP cloud applications
- Trading Partner Management: B2B EDI integration (X12, EDIFACT, RosettaNet) without custom middleware
- Integration Advisor: ML-powered mapping recommendations that accelerate complex cross-standard integrations
SAP was named a Leader in the Gartner Magic Quadrant for Integration Platform as a Service for the sixth consecutive time in March 2026.
Integration Suite as the foundation for SAP AI agents
Every SAP Business AI agent built on BTP depends on reliable, well-governed integrations. An AP exception agent calling an external bank API, or a ZATCA clearance agent submitting to Fatoora, runs on Integration Suite iFlows. Clean integrations on Integration Suite make agent development faster and more reliable.
The PI/PO to Integration Suite migration is as consequential as the ECC to S/4HANA migration — and should be planned with the same rigour, on the same timeline.
