What is the difference between the Reporter, Supporter, and Administrator roles?

Time Study has three access levels:

• Reporter - They fill out their time studies and can generate reports on their time studies only.
• Supporter -  Besides filling out their own time studies, they also have the ability to input hours and "Hold" time studies on behalf of Reporters for whom they have Access Rights. When granted additional permissions, they can also "Submit" on their assigned Reporters' behalf. Some Supporters are required to manually review their Reporters' time studies and approve or reopen them. All Supporters can generate reports on their assigned groups of Reporters, departments, and divisions. Supporters may be people such as: Administrative Assistant, Chair, Coordinator, Delegate, Department Administrator, Financial Personnel, Support Staff
• Administrator - These are our users who have global access to the data.  They usually do not alter time studies for users, but they run reports for management and analysis of the submitted time studies. Also, they manage all of the system configurations, such as User Creation and Profile Management, Time Form creation, Time Period scheduling, Email notifications, and much more.
