The Enterprise Services Repository (ES Repository) is a central repository where you define, access, and manage SOA assets such as services, data types, and so on. The repository stores the definitions and metadata of enterprise services and business processes. It also provides a central modeling and design environment for creating, aggregating, and using enterprise services. You use the Enterprise Services Builder (ES Builder) to access the objects in the ES Repository.
For more details on the ES Repository, refer to the SAP Developer Network (SDN) at https://www.sdn.sap.com → SOA Middleware → Modeling and Design.
The Enterprise Services Repository contains object types that are relevant for both SAP Process Integration and SAP Composition Environment. Only a subset of the object types in the ES Repository is relevant for SAP Composition Environment. The object types displayed in the ES Builder are restricted by means of the usage profile. For more information, see Usage Profile .
