Service Group

For OData version 4 (V4) the concept of a so-called service group has been introduced. The service group addresses the need to expose highly coherent or deeply-structured business object models of the business backend addressable on a detailed level.

A service group contains services belonging to the same business object model and hence sharing similar environment conditions. Therefore configuration and administration of a service group applies to all services in a service group, that is, routing, authorization, etc. and has to be done only once.

Services become addressable for consumers as soon as they are assigned to a service group. Several services originating from different repositories of the same SAP backend can be grouped into one service group.

Assignment of services to service groups is service version independent. So, new versions of a service are addressable out-of-the box if older versions of the same service have been assigned to a service group.

Within a service group services can define cross-service references and support requests spanning across all services of a service group, for example GET, GET with $expand or $batch.
