Departments are used to group your employees. You should assign a department to each employee on the Address/Phone Numbers page. All time reports group and summarize by departments.
ID
Enter a unique ID for the department.
Manager
Enter the deparment manager's ID. The department manager can edit time records for employees in the departments they manage.
Note: If you want managers to be able to edit time records for employees in their department, just setting the manager ID is not enough. The manager also needs the proper security profile. They must have the options to edit time records enabled in their security profile. If they have the option "View All Departments" enabled in their security profile then they can edit employees in any department.
