How can I edit a time sheet that has been approved and saved?

To edit a saved and approved timesheet, you'll need to unapprove it first, Melanie.

Here's how:

1. Navigate to Time and click on Time Entries.
2. If the Display By option is set to Date, switch to Approvals. Alternatively, you can set Display to All Workers to edit or delete time entries.
3. Select the desired date range, and in the Status dropdown menu, choose Unapproved.
4. Identify the team member for whom you wish to edit or delete time entries.
5. Next to the specific timesheet you want to modify:
   • To modify the text, click on "Edit", enter your changes, and then click "Save".

Please see my sample screenshot for reference:
