If desired, you can add additional subpages based on the object page template to your app.
The SAP Web IDE wizard allows you to create one subpage (detail page) for the object page when you create your app. This is expressed in the code as a 1:n association to the root entity and is rendered as a table in the object page.
By default, navigation from the subpage automatically generated by the wizard is available from the object page through the preset definition of a subpage for the corresponding entity set. Simply remove this to delete the subpage and corresponding link in the object page.
You can add further subpages manually in the manifest.json file post-generation, as shown below:
"sap.ui.generic.app": { "pages": [ { "entitySet": "SEPMRA_I_ProductWithDraft", "component": { "name": "sap.suite.ui.generic.template.ListReport", "list": true }, "pages": [ { "entitySet": "SEPMRA_I_ProductWithDraft", "component": { "name": "sap.suite.ui.generic.template.ObjectPage" }, "pages": [ { "entitySet": "SEPMRA_I_ProductTextWithDraft", "navigationProperty": "to_ProductText", "component": { "name": "sap.suite.ui.generic.template.ObjectPage" } } ] } ] } ] },
