Transition conditions

Question

Is it possible to set a transition to not be available if a certain user/group created the work item? The reason is that there is process that I don't want a bug to go through if our QA team reported the bug (e.g. business prioritization). After reading some, I believe I would have to create a new work item type. However, I wanted community feedback before I went ahead with publishing the new type.

Unfortunately, I don't believe there is a direct way to prevent a transition based on a condition using the Created By field.  A different work item type is definitely an option although I personally wouldn't necessarily go that far.

Answer 2

 When I read this, some ideas I had were to:

Use logic like:
At state [Something]
If Work Item Created By [QA team]
  Set data field [Business Prioritization] to
    Read-Only
    Not Required

I believe for a transition it would be more like:
Field [Business Prioritization]
  Rule - Field Condition - 'When'
     'Created By' [QA team]
        Rule - ReadOnly
        AllowExistingValue

I haven't tested these out, but they are what makes sense to me.

You can specify permissions on a transition using regular "for" and "not" attributes:

<TRANSITION from="Active" to="Resolved" for="domain\group">

Aliaksei is right. I have used that in some of mine. Not sure why I didn't remember that.

Answer 5

I think the original question got lost through the discussion. 

What I was looking for was a transaction with conditions based upon another field.
        Example: If Group A creates the bug, then the transition from Stage C to Stage D is disabled for all users.

What you presented allows only a particular group access to switch from one state to another.
        Example: Only Group A can transition from Stage C to Stage D.

These are two different scenarios. I knew how to limit a transition from one stage to another by which group is logged in. How can one limit a transition by which group created the bug no matter who is logged in?

I think this is not possible in general - our permissions are not conditional. The only workaround I see is to define completely different chains of transitions which would be based on permissions.
