Is there any way to mark the full attendance of a particular employee?

To mark the full attendance to a particular employee, follow the steps mentioned below:

Navigate to Attendance ⇒ Administration ⇒ Timesheet Settings. 

Select the specific employee for whom you want to permit the particular employee to mark the full attendance from the Timesheet Settings.

Select employee ⇒ Give Access

Now, go to the Attendance ⇒ HR Operations ⇒ TimeSheet Advanced ⇒ Give Full attendance to the employee.

Ensure attendance is at the unlocked stage. Otherwise, the changes will not be reflected for that particular month.

Note: By default, the new employee's “Full” attendance will not be allocated. To do that, you need to give specific permission from the Timesheet setting to mark that particular employee's attendance.
