To submit a Timesheet for approval, navigate to your Timesheet by selecting Timesheet from the left-hand menu:
Review your work to ensure all necessary time entries are there, then click "Submit Timesheet":
Select the days you wish to submit, add a message if you wish, then click "Submit":
This will send your Timesheet to the appropriate approver. Your timesheet will then be locked out from further entry on the days submitted.
If your timesheet is declined, you will then have the opportunity to make changes, unless your Admin also chooses to lock the week, in which case you will need to reach out to them for your next steps.
