If you discover that you have used the wrong serial/lot number for items posted to your inventory, you can always go back and correct the numbers by using a reclassification journal.
Open the Item Reclass. Journal window.
Fill in the line with the relevant information. For Help about a specific field, click the field and press F1.
Click Line, Item Tracking Lines.
Click the AssistButton in the Serial No. or Lot No. field to select the current serial/lot number.
In the New Serial No. or New Lot No. field, enter another item tracking number.
Post the journal to link the renewed item tracking numbers to the associated item ledger entry.
