Troubleshooting Serial Number & Lot Tracking Errors

1. 1
   Open the product to confirm whether it tracks lots, serials, or both.
2. 2
   Compare the label with the serial or lot entered on the receipt, pick, or transfer.
3. 3
   Check the serial's current status and location, plus any lot expiry or quarantine.
4. 4
   Compare the rejected number character by character with the physical label.
5. 5
   Search its history for an earlier receipt, reservation, transfer, or shipment.

Keep the unit aside until its identity and current custody are clear.

Use the supported receiving, return, or stock-correction action to resolve the mismatch. Do not invent a replacement serial number.

WARNING: Do not create a replacement serial or lot number to bypass a duplicate or status error; reconcile physical identity first.
