Techopedia Explains SAP Integration Repository (SAP IR)
SAP IR is a component used for SAP XI object/component design and interface mapping. SAP IR contains objects which may be processes, business rules, interfaces, data types and other scenarios.
SAP is an enterprise application integration (EAI) solution that requires external application communication to complement the global nature of business processes. SAP XI uses Web Services Definition Language (WSDL), XML Schema Definition (XSD) and Simple Object Access Protocol (SOAP) so that SAP can communicate with non-SAP applications. The usage of these features encourages developers to use SAP IR, as these technologies power business management processes, tools, data types, and message and interface mappings.
