Exposing Back-End Data as OData Services
You can use the Java implementation of the Gateway Hub (part of the Integration Gateway and in the following named as Gateway Java) to expose SAP back-end data as OData services.
The Gateway Java provides SAP back-end content as OData services using the OData Channel (ODC). ODC allows you to expose OData services by defining object models and registering a corresponding runtime data provider class.
As OData services the data from SAP back-end systems can be consumed by applications, for example, by apps or user interfaces for completing tasks.

Before you can expose SAP back-end content as OData services with Gateway Java, the following preperation steps are needed:
- Enable SSO authentication between SAP NetWeaver Application Server for Java (AS Java) and SAP back-end system.
- If you have deployed the component IW_BEP 200 SP06 or lower in the SAP backend, you need to implement the SAP note 1816779
. The component IW_BEP 200 is required to enable SAP services as OData services.
