You can integrate the OData service of your ABAP environment into the application by specifying a corresponding route in the xs-app.json file of the HTML5 module. The routing can be done either by providing a destination that points to the ABAP environment instance or by specifying the service endpoint of the ABAP environment and binding the service instance.
If the application and the instance of the ABAP environment are deployed to different subaccounts, use routing via destination.
For more information about the two types of routing, navigate to Routing via Service or Routing via Destination.
