A customer has highlighted to me that a scenario could occur where an employee submits annual leave and could then go on annual leave before it is approved, they could then retrospectively edit or cancel it to restore the days taken.
I have explained that cancelled AL would trigger a notification however once cancelled you cannot view the instance to see who cancelled it and when - as dates from the past could be moved into the future allowing you to cancel it completely - would it be possible to have sight of any leave requests that were cancelled to ensure they were cancelled legitimately?
