Register the Model / Service

The registration process of models and services is based on IMG activities and underlying repository objects. In order to allow collecting authorizations per data provider class a repository object type is available. This is integrated into transaction SU22 See also Roles in the SAP Gateway Landscape . The following repository object types are available:

• R3TR IWSV: Logical transport object for the transport of an OData Channel service in the system where IW_BEP is deployed (applicable for systems based on an SAP NetWeaver release lower than 7.40).
• R3TR IWMOLogical transport object for the transport of an OData Channel model in the system where IW_BEP is deployed, to be in line with the transport concept of an OData Channel service (applicable for systems based on an SAP NetWeaver release lower than 7.40).

The foundation on repository objects has the following impacts:

• Models and services are only transported via the transport objects.
• The external name of a service is derived from the technical name and cannot be freely defined to ensure a GTADIR connection to guarantee unique Services. You create service /MYNAMESPACE/MYSERVICE version 0001 which then results in http://host:port/sap/opu/odata/mynamespace/MYSERVICE.

The activities are part of the OData Channel implementation guide (IMG) on the backend system to maintain services / models and services:
