Integration Suite Is More Than a Migration Target. It's Where Modern SAP Integration Lives.

SAP Integration Suite is SAP's cloud integration platform on SAP Business Technology Platform (BTP), and it is the successor to SAP Process Orchestration (PI/PO) for cloud and hybrid landscapes. It bundles six core capabilities under one commercial relationship: Cloud Integration (the iflow-based message routing and transformation engine that replaces PI/PO's classic role), API Management (catalogue, gateway, security, throttling, and developer portal for SAP and non-SAP APIs), Open Connectors (pre-built adapters to 170+ non-SAP SaaS systems — Salesforce, Workday, ServiceNow, NetSuite, and more), Event Mesh (publish-subscribe event-driven integration), Integration Advisor (AI-assisted B2B/EDI mapping using SAP's machine-learning library across major B2B standards), and Trading Partner Management (B2B partner onboarding, message tracking, and EDI lifecycle). It runs on BTP rather than on-premise infrastructure, which is what makes it the integration substrate for clean core, Joule agents, and the AI estate SAP is shipping through 2026 and beyond.

Architecture, runtime, and roadmap. SAP Process Orchestration (PI/PO) is on-premise middleware running on a dedicated NetWeaver/Java stack — it served well for two decades but reaches end of mainstream maintenance on December 31, 2027, with extended maintenance to 2030. Integration Suite is cloud-native on BTP, multi-tenant, continuously updated by SAP, and integrated with the rest of the BTP services (Event Mesh, Build, AI Core, Joule). Functionally, Cloud Integration replaces classic PI/PO message routing and transformation; API Management replaces what was bolted onto PI/PO with separate tools; Open Connectors replace dozens of custom adapters; Event Mesh and Integration Advisor are net-new capabilities PI/PO did not have. The honest read: PI/PO can do many of the same integration patterns, but it cannot do them at the same cost structure, with the same AI-readiness, or under the same support clock. The Migrate PI/PO to Integration Suite practice page covers the migration approach.

Not formally — but practically, for any non-trivial integration scope, yes. S/4HANA Cloud, Public Edition (GROW) is built on BTP and assumes Integration Suite as the integration substrate; deploying integrations elsewhere is possible but works against the platform's own design and creates licence, support, and architectural friction. S/4HANA Cloud, Private Edition (RISE) gives more flexibility — many RISE customers keep PI/PO running through the 2027/2030 support window and migrate to Integration Suite in a parallel programme. Net-new customers on either model start on Integration Suite by default. The exception is small, point-to-point integrations (a single SaaS connector, a single EDI flow) where the licence and complexity overhead of Integration Suite might exceed value — but those edge cases are rare in enterprise landscapes.

Integration Suite is one of the services delivered on SAP Business Technology Platform (BTP). BTP is the umbrella: a multi-cloud platform-as-a-service running on Microsoft Azure, AWS, or Google Cloud, providing the runtime, identity, security, and database services on which SAP's cloud applications and the customer's extensions run. Integration Suite is the integration service within BTP — alongside Build (low-code), Build Code (pro-code), AI Core and Generative AI Hub (AI), and dozens of database and platform services. RISE and GROW contracts include BTP credits that can be applied to Integration Suite consumption among other services; standalone Integration Suite subscriptions are available outside RISE/GROW. See the SAP BTP page for the full platform overview.

Yes, and it is one of the strongest cases for Integration Suite over alternative integration platforms. Open Connectors ships with 170+ pre-built adapters for non-SAP SaaS systems including Salesforce, NetSuite, Workday, ServiceNow, HubSpot, Stripe, major banking gateways, and most enterprise SaaS catalogues — each is a maintained connector against the SaaS vendor's API, so when the vendor updates the API SAP updates the connector. Custom REST and SOAP APIs integrate through Cloud Integration's standard HTTPS adapter; gRPC, AMQP, JMS, and SFTP are also supported. API Management gives a unified gateway, throttling, security policy, and developer-portal experience for both SAP and non-SAP APIs — useful when the customer wants to expose SAP capability to external developers under one consistent contract.

Yes, and this is where Integration Suite materially leapfrogs classic PI/PO. Trading Partner Management provides B2B partner onboarding, message tracking, EDI lifecycle management, and visibility across every interface — the operational layer most PI/PO customers had to build separately. Integration Advisor uses SAP's machine-learning library across major B2B standards (EDIFACT, X12, ANSI, RosettaNet, GS1) to draft message mappings from the customer's input — replacing weeks of hand-coded mapping work with hours of review-and-adjust. Cloud Integration handles the actual message transformation and routing. For organisations with EDI scope (manufacturing, retail, distribution, healthcare), this combination is often the single biggest reason to accelerate the PI/PO-to-Integration-Suite migration rather than wait for the 2027 deadline.
