Decide whether the kit is still open or already completed before correcting its recorded work. An allocation reversal is an event on open work. Rework creates a new attempt for a completed kit and preserves the earlier completion.
Reverse an open allocation
The Operator can use Reverse my last scan for their own latest allocation at the station that made it, giving a reason. Check the physical item and accepted allocation before submitting. An earlier allocation, another person's allocation or another station's allocation needs a Supervisor decision.
After acceptance, inspect the changed counts and retained history. The original allocation is marked reversed rather than deleted. A repeated reversal reports that it is already reversed; it must not subtract the quantity twice.
A released serial claim may become reusable unless a retained completion of that same kit binds it. If a serial remains refused, ask the Supervisor to inspect the retained record. Do not change the serial string to escape the restriction.
Dispose of held or cancelled work
A hold release must satisfy its current source and release barriers and leaves the kit paused and claimable. A withdrawn release cannot be made usable through an ordinary hold release.
Cancellation records a physical disposition and does not release serial claims. Control the actual kit and record an honest reason. A later configuration activation is not a general way to undo a deliberate cancellation.
Rework after completion
There are no allocation reversals on a completed attempt. The Supervisor opens rework through the available controlled action. Current mode resolves requirements against current approved source and configuration. Same-plan mode reuses the frozen plan only while its source is current, release unwithdrawn and resolver supported.
The new attempt starts from zero. The earlier completion remains unchanged and gains a rework annotation. Serials from that kit's earlier completion may be scanned again on the same kit, not used to verify another kit.
Check both results
Inspect the new attempt's identity, plan and status before handing it to an Operator. On completion, retain the new result with its link to the earlier attempt. Explain the original outcome and subsequent rework separately.
If a command is stale or uncertain, refresh or reconcile it before acting again. Keep the physical kit identifiable throughout. Use history and exports when supplying evidence of the whole sequence.
