Did you get an answer?  I was going to ask a very similar question.  I have two items in stock that have the wrong serial numbers.  Who do I go about changing the serial number on items I have currently in stock? 

Hi @Karl Brooks  and @lzettel Please try the below adjustment option, and let me know if this resolves your issue.

Note: If you have more items, you can prepare the data in an excel file and use the “Upload” to upload the adjustment data in bulk.

Thanks

Thank you, @ChandrasekharM.  That worked wonderfully to change the serial numbers.  Everyone has been so helpful here in the community.  This is only my second post and I’ve gotten resolution both times. Thanks again.

Hi @lzettel Thanks for the Confirmation. Requesting you to mark it as answer.

Thanks

@ChandrasekharM, I would mark it as answered, but I do not know how to do that.  if you guide me through it, I will mark it answered.

Thank you for the kind words @lzettel  and solution @ChandrasekharM. Only the original poster and an admin/moderator can mark as answered. I have taken care of that 

Thanks @Chris Hackett
