Maintain one reference
The batch identifier should be consistent where it appears on the label, document register and applicable paperwork. A project may also have a separate enquiry or order reference; these should not be confused.
Manage revisions
If a document is revised, retain the relationship to the earlier record and identify which version applies. A new file name alone does not explain what changed or whether a previous document remains valid.
Ask about a mismatch
If the label and document do not match, pause the document acceptance and request clarification. Traceability is a record relationship, not a quality claim inferred from professional-looking packaging.
