To alter a timesheet, first select the correct date.
To do this, use the calendar, at top right of the Timesheet tab.
When selected, you'll find all the registered hours of the given day, from the department you're currently in.
When the day is closed, recognizable by the green button Open day on the timesheet, you will need to open the timesheet to edit the worked hours. You do this by clicking on this green button.
The timesheet can now be modified. Once you've made all changes, you can click Submit to save any alterations.
Removing hours worked
It is not possible to remove worked shifts. However, the shift can be set to Declined. By rejecting the shift, the hours are not included in the employee's salary, timesheets or payroll.
Once you're done the day can be closed again.
