When a job is no longer active, you will need to set a Finish Date so that employees are not able to submit timesheet data that falls outside the time the job was active.
You can set this date whenever you like. For example, if the end date is known when you create a new job, you can set it at that time.
Enter a Finish Date
Go to Users > Employees > select the employee > select the job > Job Details.
Select the Finish Date from the drop-down calendar.
