When an employee completes an expense report, the expenses must be paid out within a week. When reports are completed, the leader must approve the report. If the manager approves then finance must pay out the money. If the report is pending approval, payment cannot be made. If the leader rejects the report then he must approve later in order for payment to be made. The employee can undo the expense report, and if it completes the case. When payment has been made, the case is closed.
