Service Provisioning

In this section you can find information about how to develop a provider application in SAP Gateway Foundation and the additional steps needed to have a working OData version 4 (V4) service.

You need to perform the following steps:

1. You define the object model of your service.

   This is done by developing a model provider class. The Entity Data Model (EDM) – exposed via the metadata document - is the OData representation of this model. The model definition is also needed by the framework to process any request against the service.

2. You implement the business data access of your service. This is done by developing a data provider class.

3. You register the service.

   This defines the service’s unique name and assigns the model and data provider classes to it. The service registration is done with an SAP Gateway Foundation backend component tool.

4. You assign your service to a service group.

   Service groups simply group together several services. Customizing is done for service groups and not individual services.

5. You publish the service, that is, you publish the service group your service has been assigned to.

   A service is only accessible via OData in the context of a service group and only after the service group has been published. The service group publication is done with a hub component tool. A service group publication is a customizing entry on the hub.
