INTEGRATIONS

Connecting SAP S/4HANA Cloud Public Edition to your other applications, data sources, and business partners.

SAP Integration Suite is SAP's integration platform as a service (iPaaS), part of SAP Business Technology Platform (BTP). It connects SAP S/4HANA Cloud Public Edition to other SAP and non-SAP applications, moving data between systems, transforming formats, and applying business logic along the way.

At its core is the Integration Engine, where integration flows are designed, deployed, and monitored. SAP maintains a library of prebuilt integration content covering thousands of commonly used third-party applications, reducing the effort required to connect standard systems such as banking platforms, tax engines, and logistics providers. Alongside the Integration Engine sits API Management: a gateway and developer portal for publishing, securing, and monitoring APIs from both SAP and non-SAP systems.

Because SAP S/4HANA Cloud Public Edition follows the Clean Core principle, integrations are built outside the ERP core rather than through direct modification of it. SAP Integration Suite is where that connective layer lives, which keeps the core upgrade-stable while your integration landscape continues to evolve.

What SAP Integration Suite covers

SAP Integration Suite supports several integration scenarios side by side.

Application and process integration link business processes across systems, typically using prebuilt or custom integration flows.
API management exposes and secures data and functionality as reusable APIs, which is increasingly the standard for connecting SAP S/4HANA Cloud Public Edition to modern, API-first architectures.
Event-driven integration lets systems react to business events, such as a goods receipt or a changed sales order, as they happen, rather than through scheduled batch jobs. B2B integration handles structured data exchange with external trading partners, and hybrid integration bridges cloud and on-premises systems in a landscape that includes both.

Recent releases have added AI-assisted tooling to the platform itself, including natural-language flow generation and automated anomaly detection on API traffic, aimed at reducing the manual effort of building and monitoring integrations.

Integration Features SAP S/4HANA Cloud Public Edition ( Release august 2026)

Available API: 945

SAP S/4HANA Cloud Public Edition relies heavily on APIs to connect with external systems, using standard protocols to ensure secure and efficient data exchange.

OData V2

Purpose: Standard SAP cloud integration and extensibility framework.

Format: XML, JSON

Strengths: Full CRUD capabilities; mature, widespread ecosystem.

Limitations: Synchronous processing only; heavier payloads than V4.

OData V4

Purpose: Modern standard for high-performance SAP data exchange.

Format: Optimized JSON

Strengths: Reduced payload size; advanced batch request sequencing.

Limitations: Fewer available standard APIs compared to OData V2.

REST

Purpose: Custom, lightweight, and direct system communication.

Format: Primarily JSON

Strengths: Highly flexible; independent of OData metadata structure.

Limitations: No built-in standard schema; requires manual modeling.

SOAP

Purpose: Legacy, heavy-duty enterprise business-to-business (B2B) messaging.

Format: Strictly XML

Strengths: Asynchronous processing; built-in reliable messaging (WS-RM).

Limitations: High network overhead due to bulky XML headers.

Available Business Events: 151

In SAP S/4HANA Cloud Public Edition, an SAP Business Event is a notification automatically triggered whenever a change occurs to a core Business Object (like a Business Partner, Sales Order, or Journal Entry). These events use a standardized format to notify external systems when data is created, updated, or deleted, enabling real-time, event-driven integrations.

Available BaDi's: 1665

A BAdI (Business Add-In) is an object-oriented enhancement technique in SAP. It serves as a plug-in point within standard SAP code, allowing developers to inject custom business logic or validations without altering the core programming (Clean Core Concept).

Available CDS Views: 8983

In SAP, CDS (Core Data Services) Views are a modern data modeling framework that lets developers define database views enriched with business semantics directly in the application layer. They serve as intelligent, reusable "virtual reports" that process complex data logic—such as aggregations and filters—directly on the high-speed SAP HANA database.

How it fits into your S/4HANA Cloud landscape

Access to SAP Integration Suite is included with every SAP S/4HANA Cloud Public Edition subscription, as part of the BTP entitlement that comes with the product. For most implementations, it is the default answer to "how do we connect this system to S/4HANA" — whether that system is a legacy application staying in place, a specialized cloud solution, or an external partner. Because Integration Suite operates outside the ERP core, adding or changing an integration does not touch the standard system, which is what allows SAP S/4HANA Cloud Public Edition to receive twice-yearly updates without breaking existing connections.
