Unable to add new rows in detail inside a detail from portal user.
I am trying to add a new record in a detail inside to another one. The + button is missing even the object permission are configured for this role. (attach Creatio1.png)
When I change the detail with option "Make the list editable" (attach Creatio2.png), the button is shown but the business rules and filters are not applied. (attach Creatio3.png)
Any idea how to fix this issue?
