A traceability table must work in both directions. From the customer's vehicle you can find the installed part batch; from a problem batch you can find the remaining stock and the installed vehicles. Registering only the purchase amount cannot complete this kind of tracking.
Check Physical Identity on Receiving
Parts for a Chery Tiggo 9 are checked first against the applicable VINs, the part number and the supplier material. When the label, packaging and purchase order disagree, quarantine the item pending verification rather than rewriting labels to get it on the shelf faster. Model fitment does not prove the component's source is genuine.
| Relationship | Material to keep | Role when an anomaly occurs |
|---|---|---|
| Supplier to batch | Purchase order, delivery note and label | Find the original supplier |
| Batch to stock | Bin location and issue/return records | Locate parts awaiting use |
| Part to vehicle | Installation work order and VIN | Confirm which customers to contact |
The receiving table can keep the purchase relationship, the delivery material and the actual label content together, with the receiver checking whether they all point to the current item. When packaging is damaged or markings are unclear, photograph the visible state and ask the supplier, rather than printing an unverified new label over the original markings.
Fitment judgment and source verification are recommended to be signed separately. Technical staff state whether the part can be used on authorized vehicles, purchasing staff confirm the source material, and the warehouse arranges shelving after the necessary confirmations are complete. Items still to be explained are marked separately so that workshop urgency does not mix them into ordinary stock.
Update Correspondence When the Substitute Part Changes
Obtain the fitment and substitution basis before recording the actually installed version. The GS1 traceability standard distinguishes identification of products, batches and single units and can be used to design linked records; it does not mean the part has passed Paraguay's quality certification. When a batch problem appears, first lock down the scope, with technical and service roles deciding the inspection and notification arrangements.
Issue records can start from the part actually taken out, link the corresponding work order and vehicle, and have the service technician confirm the actual installation. Parts returned uninstalled state the reason and are received back by the warehouse. After a substitute part is authorized, update the actual identity while keeping the original request and approval process; do not just change the part name.
For a problem notification, first look up unused stock by the known batch, then trace installed vehicles along the issue records. Entries with unclear scope are referred to the supplier and technical staff for verification, and service waits for confirmation before arranging contact. Do not announce to unrelated customers that their vehicle must be faulty.
Tracing Back from an Installed Part to Its Source
Example only; the contract and the physical vehicle prevail. After a given VIN is repaired, the part source needs checking, but the work order only left a short product name. The service technician can look up the original issue record, the warehouse matches the actual batch and receiving material, and purchasing then contacts the supplier to complete the identity basis. What cannot be confirmed stays a gap; do not substitute the label of same-named stock.
After the gap is closed, write the valid relationship back into the vehicle and stock records and keep the original reason for the gap. Then trace other destinations from the same batch in reverse and check whether similar breakpoints exist. If information is still insufficient, the responsible person decides the further inspection arrangements; filling the traceability table is not treated as proof of quality.
FAQ
Can parts from the same supplier be mixed across batches?
Keep the original batch identity; do not merge to the point of untraceability.
Can parts be received if the packaging is lost?
Check other credible identification material first; items of unknown source are quarantined.
Can returned parts be resold directly?
First confirm whether they were used, damaged and what disposal requirements apply.
Is tracing only high-value parts enough?
Set the scope by risk and applicable requirements; price alone must not decide it.
When organizing parts supply needs, provide the part number, the use and the traceability information to be retained, via the Starvia contact page or WhatsApp.
