HI @mstuber64 

Yes, you do that during the assembly process. 

Click the Line Details button and it will pop up for you to enter the Serial number.

Hi @kbeatty21 

I did tried that before, but it does not let me add it.

Am I missing something during setup or in the stock item master?

Thank you!

What is the Lot/Serial Class on the actual item?

Can you confirm that the Lot/Serial Class of the Kit is a serialized one?
If not that could be the root cause as the system doesn’t expect a Serial Number.

@kbeatty21 

You are right. I created a new item and played with the different lot/serial classes and now it works.

Thank you so much for your help with this.
