An employees should be able to apply for leave within their previous active enrollment.

There are 2 scenarios where this change can happen:

1. A change of accrual frequency from monthly to annually leading into the fact that the employee need to be un-enrolled from the monthly plan and re-enrolled into the annual plan. This will only change plans while the leave types will stay the same.
2. Current: Employee is not able to submit the time off in the previously active monthly Vacation leave plan
3. Expected: Employees should be able to to submit the time off in the previously active Vacation leave plan
4. An FTE change needing un-enrolment + re-enrolment into the same leave plan to calculate the correct pro-rated accrual amount for when the employee had an FTE of 0.5 and when the employee had an FTE of 1. Also here an employee cannot submit any time off request for their previous enrolment.
