Copy a Timesheet Dialog Box
Use the Copy a Timesheet dialog box to select another timesheet whose information you want to copy into the current timesheet.
When you copy a timesheet, all project, phase, task, labor code, labor category combinations, and comments are copied from the selected timesheet to the timesheet that you currently have open. Regular and overtime hours from the selected timesheet are not copied. Any existing entries to the timesheet receiving the copied data are not overwritten.
You can copy data from an existing timesheet into a new timesheet at any time, even if the existing timesheet is in a closed labor period.
