I made a new CB project which generated several default trackers that I didn't need. When attempting to configure and delete the trackers, I receive a message that states, as attached, 'User has no permission to view working-sets", and the tracker cannot be deleted. For now, I have just hidden trackers that are not relevant.
It's because that tracker is included inside Working set. and you don't have enough permission to view the WS. if u want to remove the Tracker, then u need to ask someone to delete the tracker who has modify access of that WS.
