SAP Integration Suite is the integration platform on SAP Business Technology Platform (BTP) — which SAP now calls SAP Business AI Platform (BAIP), the AI-first evolution of SAP BTP — for connecting SAP S/4HANA Cloud Public Edition to the rest of an organization's application landscape. Because a cloud ERP rarely stands alone, integration is usually where a Public Edition landscape begins: the ERP has to exchange data and events with other SAP applications, non-SAP systems, and business partners. SAP Integration Suite provides a unified, business-centric way to do that across APIs, processes, events, and business-to-business flows, so integrations are governed and reusable rather than point-to-point and fragile.
Like the other platform capabilities, it connects to SAP S/4HANA Cloud Public Edition through released interfaces, which keeps integration clean-core compliant: the ERP core stays standard, and the connectivity, mapping, and orchestration live on the platform.
SAP Integration Suite brings together four integration styles in one place:
Cloud Integration builds and runs integration flows between cloud and on-premises applications, SAP and non-SAP, with a large library of prebuilt integration flows and connectors as a starting point.
API Management publishes, secures, and monitors APIs, so that access to ERP data and services is controlled, scalable, and observable.
Event Mesh enables event-driven integration, letting applications publish and consume business events asynchronously so systems can react in near real time and stay loosely coupled. Advanced Event Mesh extends this to larger, distributed event-driven landscapes.
B2B integration, supported by tools for trading-partner management and for designing and mapping message interfaces, connects an organization to its business partners using common industry standards.
Together, these cover the main ways SAP S/4HANA Cloud Public Edition needs to connect: request-response through APIs, event-driven notifications, scheduled or streamed data flows, and partner-facing B2B exchange.
Integration with Public Edition uses the ERP's released APIs and business events. An integration flow calls released APIs to read or write ERP data, or subscribes to released business events to react when something happens in the ERP. API Management governs how those interfaces are exposed and consumed, and Event Mesh carries the events. Because everything is built on released interfaces and runs on the platform, upgrades to the ERP core do not break the integration layer.
Prebuilt integration content shortens the path for common scenarios, but the same clean-core discipline applies: prefer released interfaces, keep integration logic on the platform, and avoid any design that would depend on internal ERP objects.
Scope integration around Public Edition in three steps:
For system-to-system integration, the value is in the connection itself; where the requirement is really about orchestrating a human business process, see [SAP Build Process Automation with SAP S/4HANA Cloud Public Edition]. For the broader set of extension mechanisms, see Extensibility options in SAP S/4HANA Cloud Public Edition, and for platform orientation, see [What is SAP Business Technology Platform (BTP) and how does it relate to SAP S/4HANA Cloud Public Edition?].
SAP Integration Suite is the integration platform on SAP Business Technology Platform for connecting SAP S/4HANA Cloud Public Edition to other SAP and non-SAP systems and to business partners. It provides a unified approach across APIs, processes, events, and business-to-business integration.
Cloud Integration for building integration flows with prebuilt content and connectors, API Management for publishing and securing APIs, Event Mesh (and Advanced Event Mesh) for event-driven integration, and B2B integration with trading-partner management for partner exchange.
Through the ERP's released APIs and business events. Integration flows call released APIs to read or write ERP data or subscribe to released events to react to changes. Because everything uses released interfaces and runs on the platform, upgrades to the ERP core do not break the integration layer.
Yes, when it uses released interfaces. The ERP core stays standard while connectivity, mapping, and orchestration live on the platform. The clean-core discipline is to prefer released interfaces and avoid designs that depend on internal ERP objects.
API-based integration is request-response: a system asks for or sends data through an API. Event-based integration is asynchronous: the ERP publishes a business event and interested systems consume it, which keeps systems loosely coupled and able to react in near real time.
Yes. It connects SAP and non-SAP, cloud and on-premise applications, with a large library of prebuilt integration flows and connectors, and it supports B2B exchange with business partners using common industry standards.
Event Mesh lets applications publish and consume business events asynchronously for event-driven, loosely coupled integration. Advanced Event Mesh extends this to larger, distributed event-driven landscapes with more advanced event brokering.
For each connected system, catalog what data and events must flow, in which direction, how often, and with what latency, then choose the style per flow — APIs for request-response, Event Mesh for decoupling, Cloud Integration for orchestrated flows, and B2B for partners — and design in security, monitoring, and error handling from the start.
Use SAP Integration Suite when the value is in the system-to-system connection itself. Use SAP Build Process Automation when the requirement is really about orchestrating a human business process with approvals, rules, and forms.
Use SAP's current SAP Integration Suite documentation, the released API and event catalog for SAP S/4HANA Cloud Public Edition, and current SAP guidance. Capabilities, prebuilt content, and connectors evolve with each release, so recheck before finalizing a design.
