Handling wrong or damaged parts requires a single primary record. Use unpacking and visual evidence on arrival as the baseline and keep it in sync with changes to part numbers, quantities and packaging labels and replacement, return and cost responsibility. Keep the unopened packaging, labels and photos of the damage when the goods arrive, and check the part numbers before requesting a replacement or filing a claim, so responsibility can be determined. Keep unpacking and visual evidence on arrival and part numbers, quantities and packaging labels on one versioned master sheet; when replacement, return and cost responsibility changes, update the records before signing off.
