Hi Jonathan.gonzalez 

If the error is recent and if the stock still exist, best would be to delete the transaction and re-create it.

Else, there are no utilities to fix this.

If the stock exists, I guess you can always do a stock count (or misc. issue & mic. receipt) but then the traceability is lost. So probably the best way, would be to create a work order (where the parent product is the only component as well), and track the incorrect SN as component and produce the 'correct' SN. At least, the stock value and traceability is good at the end.

After the shipment, I can only think to do a customer return and process to the SN change as explained in the previous sentence. Finally, you re-do the shipment.

Anyone has a better suggestion?

Thanks Julien, good workaround.

 hi Julien Patureau Is it possible to change the serial number during the packing process, or is the serial number even displayed during this process?

Hi Sagex 

I have never used before SN with packing so I don't know.

Thanks ))
