Scenario:
The Web TimeSheet Administrator is not able to use the Copy From feature in the timesheet. However a basic timesheet user is able to copy timesheet data using the Copy From feature.
Cause:
This usually happens if the Administrator is accessing the timesheet from the Historical TimeSheet page. If so the Administrator will not find the Copy From button in the timesheet. This is because, the Copy From button is only available in the TimeSheet page.
Resolution:
For the administrator to use the Copy From feature in an end user's timesheet, the administrator has to login using the end user's credentials or switch to the users profile as a Substitute user.
Note:
To set up a user as another user's Substitute user follow the instructions in the link given below.
