The role category indicates the hierarchy of participants in relation to other participants in the same role. The category is set in the Role Assignment pane
Role assignments can be assigned a rank from 1 to 9, with 1 being the lowest and 9 being the highest. Participants can reassign instances based on their role ranking.
Participants with higher ranks can delegate instances to participants with lower ranks if they have been given the delegate permission. Participants with lower ranks can escalate work list instances to participants with higher ranks if they have been given the escalate permission. Participants with the peer assignment permission can assign instances to other participants with the same rank.
