You must have Manage Exceptions permission in the department to make an employee an exception. By default, users with the role of Compliance Supervisor, Rule Admin, or User Admin have this permission.
To designate an employee as an exception
If Compliance Accelerator lists a lot of departments, you can filter the list with the fields at the top of the pane. As well as filtering the departments by name, you can choose whether to list any exception employees, folders, and reviewers that are associated with them.
You can select multiple adjacent names by holding down the Shift key and clicking the first and last name in the range. To select multiple, nonadjacent names, hold down the Ctrl key and click the required names.
