Some points, like process variables, are read only. Their value can't be set even if you are super-user.
I see there is the "settable override" in the graphical view and I can assign a user's permission on a point from SET to READ.
With more than a couple of users and potentially hundreds of points assigning the READ/SET property for each user becomes a lot of work!
Could this property be assigned to the point in the data source edit screen and be effective for all users?
If you think this is a good idea I'll get to work on implementing it
