When a requisition is finally closed (meaning no further action will be taken), its authorization status becomes Finally Closed. This is distinct from Cancel or regular Closed status.
Once a requisition has gone through the Finally Close process, its authorization status is set to Finally Closed, which permanently prevents any further activity (additional receipts, changes, or reopening) against it. This is a distinct, terminal status separate from a simple Cancel or Closed status, which can sometimes still be reversed or reopened.
