Enabling SAP back-end content as OData services using Integration Gateway.
Integration Gateway provisions 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. There are two ODC application components: the business data provider and the metadata provider. An ODC data provider implements a single interface that is very close to the OData Protocol. OData Channel applications obtain access to common framework services, for example, logging or transaction handling, using a set of agents called “Common Service Exposure”. These agents wrap existing framework services in a way that OData Channel applications can easily consume.
Integration Gateway provides Custom Processors, a plug-in mechanism to provide your own logic on top of the output generated by the API toolkit for SAP Mobile Platform to enhance / modify the content. See Defining Custom Code on https://help.hana.ondemand.com. The relevant content is located in .
