A batch reference creates a connection between a physical item and the records that describe it. The same product can have multiple batches, and the same batch may be represented by several document pages. This resource explains how product identity, lot numbers and report identifiers work together. Keeping those references visible helps readers avoid applying a historical result to a different material, pack format or batch without an established relationship.
Use more than one identifier
Product name, lot number and report identifier each serve a different purpose. The name tells a reader which material is being discussed, the lot distinguishes a batch, and the report identifier points to a particular document. Keeping all three prevents similarly named records from being merged simply because their text looks alike.
Keep a clear document history
When a document is updated or a new batch becomes available, retain the distinction between the old and new records. A current product page can link to more than one historical batch, provided each is clearly identified. Replacing a file without changing its visible reference can make the document history difficult to understand.
Follow the actual supplied item
A clear relationship between the container label, material record and relevant report is more useful than a general archive link. Preserve each identifier when records are shared between purchasing and technical colleagues.
