When going to "Open OData Service" tab under the KUT field setings in adaptation mode, you can't see any option to extend the field to be used on DWB templates.

Reproducing the Issue
1. Go to Invoices WoC.
2. Open "ABC" invoice as example.
--> Check field "123" is added on header.
3. Go to adaptation mode.
4. Edit the "123" KUT field.
5. Open Odata Service tab.
--> There is no option appearing and you cant expand this field to the templates data workbench.
The KUT field is created for BO "LEAN_INVOICE".
Service 'leaninvoice' is consuming BO LEAN_INVOICE which is non extensible. Hence it is not available for adding KUT property in Adaptation mode.
This is the system behavior.
