What is SAP Integration?

SAP integration is the controlled exchange of customer, product, inventory, order, invoice, finance, and production data between SAP ERP or SAP S/4HANA and other systems. These systems may include an e-commerce site, CRM, warehouse management platform, dealer portal, reporting tool, or custom application.

How It Works

The integration method depends on the SAP version and enterprise architecture. Teams may use OData services, RFC/BAPI calls, IDoc messages, file transfer, middleware, or event-driven patterns. In every case, authentication, authorization, field mapping, error queues, and retry strategy must be designed.

What to Consider

Master data quality in SAP is the foundation of the integration. If customer code, material number, unit of measure, pricing condition, tax class, or warehouse data is wrong, the external transaction will also be wrong. In large organizations, change management, test environments, approval workflows, and logging are as important as the live connection.

ERP, API integration, and master data are core concepts in SAP integration. Good design starts by defining which system owns each piece of data.
