Hi Nazarene,
Just want to add another alternative, which I think wasn't mentioned above.
If you have set up your workflow to find the correct approver, you can teach your users to use the "Services for Object" pushbutton (the one just under the command field in the upper left corner), then select in the menu Workflow --> Overview. If your workflow doesn't show a specific name in the column agent:
then they can click on the "Information..." link there and find the exact name(s).
Unfortunately, if you have several release codes that need to approve the PReq one after another, then you will only see the WF of the pending codes in the WF overview. The WF's for the other codes will be only created when the previous approvals have been given.
Hope this is helpful.
