I am creating a simple list (imagine a request for instance) in Sharepoint. This list can be modified by the user, but the field "Status" (Approved, rejected, waiting, -And any status I could imagine) can only be modified by the group of manager.
After searching a lot of on the web, I understood that "read-only" is not so easy out of the box in Sharepoint.
So, after reading this link (Read-only column in a SharePoint list) I tried to create a lookup to a second list that is only the manager can edit/write, and used a lookup.
Unfortunately, after some tests, the user is still able to modify this field.
Is that a correct approach, or I am doing something wrong?
I hope my question is clear, because that sounds like a basic feature.
