More about Work Group data instances
Work groups are a primary base for many standard reports.
You can set up work groups to correspond to a fourth level in an organization hierarchy (below organization units). However, work groups can cross organization units and divisions. A correspondence between work groups and divisions or organization units is not required.
A work group data instance can identify one user who is the work group supervisor. The system can use supervisor information in a work group for notification tasks and routing tasks.
