For serialized work, define which field identifies the item type and which identifies the individual unit. A system that accepts a product code may still need a separate serial value before it can complete the intended traceability record.
Write the data contract
| Field | Question for the system owner |
|---|---|
| Item identifier | Which product or configuration does it select? |
| Serial value | What format and uniqueness scope apply? |
| Job association | Which order, inspection or asset should receive it? |
| Existing value | Should a repeated unit be blocked, reviewed or processed differently? |
Test association, not just text entry
Use two known sample units of the same item type, plus an already-recorded sample unit. Confirm that each distinct serial goes to the intended record and that the existing unit receives the approved response. Compare the original value character by character with the saved value, including case and leading zeros where the system specification requires them.
If a GS1 symbol carries multiple elements, ask the app vendor for the exact mapping and parser. A generic product-code field should not silently absorb the entire compound string.
The T1 listing identifies its current configuration as without a Honeywell scanner. It does not establish serial parsing, uniqueness enforcement or traceability-system approval. Those remain app and integration requirements.
This guide reports no serialized-workflow test. See GS1 separator and parsing checks for compound data. Send Phonemax a sanitized field specification and the proposed software.
