Hi,
This query is regarding extending an ABAP CDS view and adding new entity types to enable a new tab in the SAP provided standard app
1.Below is the landing page of app “Find Maintenance Order”

2. Now, click on any of the record and we navigate to the detail page as below. Here we want to add a new tab (XYZ) with some additional information.

3. To achieve this we have extended the CDS view C_OBJPGMAINTORDER and have added some of our application specific fields and publicly exposed the associations as below:

4. We checked the gateway project, there is neither a new association nor any entity set. These 2 things are visible in hierarchy only because this hierarchy is made up of the associations maintained in the CDS view. But we want them to be available as new entity types.
