I have setup Tasks in a project and budgeted hours to each. Employees enter time for this project under tasks. The budget hours are reached and I want to "lock-out" all employees from this project. I put an end date to the task and tried other ways in Tasks to lock emplyees out but their time sheets show an error message preventing them from submitting timesheet as they have time entered before the date of the lockout. How do I change setting to make sure employees can still submit their time sheet.
