Do not ship while the unpaved-road noise item is open. Before reusing an earlier conclusion, re-check the suspension connections, the interior fixing, and the road-test records, and re-approve if the source has changed. Handling the unpaved-road noise change can be linked to the earlier steps in this import order checklist. Copy the unpaved-road noise material to the next batch only after this batch's version is confirmed, so that the error does not spread.
