The Approval Server can route a request to a role instead of to an individual. When you route to a role, the request is routed to all members of the role. You specify whether one member of the role can approve a request or whether all members must approve it.
The Overdue Oversight role is an example of the use of roles in the Lunch Scheduler sample application. This rule works with the Rule-Based process to route approvals for an overdue account to the members of the Overdue Oversight role.
