Hi,

We have role delegation enabled for line manager. User A proxy as the line manager ( because the line manager delegate his role to the user A), user A is not able see anything in the document type dropdown. Navigation: My client group -> Document records -> search for the line manager's direct report -> Add -> nothing is in the dropdown.

The line manager himself has the access to document type LOV but no the user A.

Any thoughts here ?
