The Unanet system uses a series of Statuses in order to keep track of where a particular Timesheet, Leave Request, Expense Report, or Expense Request is located in the approval process.
You can run these reports in Reports > People Reports (Time & Expense Only) > STATUS REPORTS. Additionally, a user may view his or her own expense reports, leave requests, and timesheet statuses in Reports > User Reports > STATUS REPORTS.
These reports are very useful in determining whose action is pending next. For example, any person approving that appears in the Pending Approval column has yet to process their approvals.
