Here's a detailed article on Hybrid Integration Scenarios within the context of SAP B2B Integration:
In today’s interconnected digital landscape, businesses increasingly rely on seamless integration with external partners, customers, and suppliers. SAP B2B (Business-to-Business) Integration enables organizations to establish these connections effectively. However, due to the diversity of systems, protocols, and integration styles in a typical enterprise, hybrid integration scenarios have become essential. These scenarios combine on-premise and cloud-based technologies to meet both legacy and modern integration requirements.
Hybrid integration refers to the strategy of connecting applications, data, and processes across on-premise and cloud environments. In the SAP context, it often means integrating traditional SAP ERP systems with cloud-based solutions such as SAP S/4HANA Cloud, SAP Integration Suite, and third-party applications or platforms.
This approach offers flexibility, scalability, and speed — crucial in B2B contexts where organizations must exchange documents and data in real time across diverse IT ecosystems.
SAP provides several tools and platforms that support hybrid integration:
SAP Integration Suite (formerly CPI)
A cloud-based integration platform that supports multiple integration styles (API-based, event-based, and message-based) and comes with pre-packaged B2B content.
SAP Process Orchestration (SAP PO)
An on-premise middleware for integrating internal SAP and non-SAP systems, often used in legacy setups.
API Management
Enables secure, managed access to services and APIs between internal and external systems.
EDI (Electronic Data Interchange)
B2B integrations often rely on EDI standards (e.g., EDIFACT, ANSI X12) for document exchanges like purchase orders, invoices, and shipping notices.
An enterprise running SAP ECC on-premise may need to connect with a logistics partner using a cloud-based API or EDI gateway. In this case:
Many businesses have legacy EDI systems that need to be modernized without a full rip-and-replace approach.
Some partners prefer RESTful APIs over EDI. A hybrid model allows:
SAP Global Trade Services (GTS), often deployed on-premise, may integrate with cloud customs platforms or regulatory systems.

Best Practices:
Hybrid integration scenarios are crucial for enabling agile, scalable, and secure B2B integration in the SAP ecosystem. By strategically combining cloud-based tools like SAP Integration Suite with on-premise middleware and systems, organizations can meet diverse partner requirements, maintain regulatory compliance, and adapt to rapid market changes. As digital transformation continues, mastering hybrid integration will be a competitive advantage for SAP-driven enterprises.
