How Do I Track Lot Numbers From Supplier to Customer?
To track lot numbers from supplier to customer, record the supplier lot of every material received, link the material lots used to each production batch and link each batch to the customer shipments that contained it.
In Jestor, material lots, batches and shipments are connected, so you can trace a problem forward to customers or backward to suppliers.
Why does traceability matter?
When a supplier reports a problem with a material lot, the factory must know which products used it and where they went.
When a customer reports a defect, the factory must know which materials and process were involved.
Without links, this investigation takes days and may be incomplete.
What problems does lot traceability solve?
- Slow responses to supplier alerts
- Unknown scope of affected products
- Complaints investigated without data
- Broad recalls instead of targeted ones
- Customer trust damaged by slow answers
