After redefining an OData Service like it is described here, you also have to add your new service in your Extension Project, so that the App knows, that it should use your redefined service instead of the default one. In the WebIDE there was a wizard that helped you with this task. In BAS there is also a wizard, but only for Adaptions Projects. For a classic extension project, there is no wizard anymore, and you have to manually add your new service to the manifest.json. But it is quite simple. You have to add your new service as data source and then also as a model. When no model name is provided, it will be used as default model.
