Finding a lot alone does not show its container and route links.

Drill record

  • Sample lot
  • Linked containers
  • Route and location
  • Block status

Trace both ways

Compare product-to-container and container-to-product records. Block units in the system and verify physical location.

Check subsequent use. Reconcile cleaning, return and next-trip records; log gaps with owner and time.

The drill is complete only when the container flow is explained too.
