To edit a shift record all you need to do is click on the shift, this will bring up the details of that shift on the right hand side of the screen. Here you can edit the hours worked to reflect the time an employee was actually present.
At the top you will see the initial scheduled time inputted into the Scheduler.
If your employees are required to 'Check In/Out' on their app then the recorded data of this will be added to the Timesheet. Check out this article to understand how Time & Attendance works within Timesheets.
Once you have made your changes and the hours shown are correct to the hours worked, then hit 'Save & Approve' at the bottom of the window, this will approve this entry which will be reflected in the Timesheet.
If you have made an error in an Approved entry and need to go back in and edit it, simply click the entry within the sheet to open it and make your changes.
You can also 'Unapprove' an entry so it returns to its initial unapproved state, this will flag to another member of staff that this entry still needs to be looked at. This may be the case if 2-step sign off has been turned on and your Payroll Department want you to check this entry again and make changes, they will also be able to leave a comment on this entry to give you some insight if needs be.
If all the hours for a day/employee are correct and do not need to be edited you can approve them all in one go by clicking on the 'tick' icon next to each day/employee.
Once all the hours in your Timesheet are correct hit 'Submit' and this will send of the Timesheet.
