[rt-users] Precedence for group rights for custom fields vs. queue

	You're situation is similar to ours with a few differences. We only 
move the ticket to a "support" queue once, after it is initally approved 
for work. Once there, it is modified by the support personnel until it 
is ready for our "QA" workFlow. We have several Custom Fields in play 
for that process and, of course, allow only members of a certain group 
to modify those fields. Those "Approvers CANNOT modify any other field 
in the ticket, with the exception of comments, but those are two 
different permissions.
	You pose a fairly tricky problem, but question1 doesn't quite seem to 
specifically address it.
	Question 1: Do CF rights override Queue/Group rights? They don't 
interrelate at all, other than when a CF IS applied to a Queue, the CF 
rights of a group come into play. The CF group rights are for a CF, 
regardless of queue. RT sees this as two separate issues. I have an 
instance where a CF is applied to a queue but no one can see it or 
modify it. I use it internally for certain scrip conditions and I set it 
internally based on other conditions (this, by the way, might be an idea 
to consider for your problem). Having rights to a CF in no way impinges 
on the rights you granted for a queue.
	Question 2 & 3: I would consider the following:
		1) Create a CF that NO ONE can modify. Apply it to the appropriate queues.
		2) Write a scrip that will modify that new CF with a more explicit 
description of the value expressed by the CF that was changed by the 
approvers. Condition that action on a change to the ORIGINAL CF that the 
approvers CAN modify.
		3) Grant "SeeCustomField" (ONLY!!!) for the appropriate groups to that 
new CF.
		4) Do not apply the old CF to the queues where the approvers are only 
supposed to be "looking" at them.

	This should allow you approvers to modify the CF in the "Approval" 
queue where they have access AND at the same time, you are updating the 
CF that anyone can SEE (by not change) in the non-approval queue.
	I hope I'm describing this in an understandable way. The terms we use 
in RT CAN be a little misleading, sometimes. Hope this helps.
