Another scenario could be that a Client is attended by a different Carer to the one who was actually assigned to the Task. Because an unscheduled Carer clocked in/out, the system will move this Captured Attendance to the Task Attendance screen, from where you will be able to link it with the Scheduled Task. Once you link the Captured Attendance with the Task, the scheduled Carer will be replaced by the one who actually performed the Task.
