Hello, 

I didn't find a way to have a generic barcode to increment the number of article when doing a transfer, do you know if there is a way to have one in odoo ?

I aware of the product packaging but it is link to the article. From my understanding, I cannot use the packaging of article A for article B.

if it help to understand the request the following scenario : 
using the barcode App I scan the reference (ref A) I want to transfer, then the "generic packaging" of 50 pieces so it increment to 50 pieces the transfer. 

this generic barcode would work for any article since it would just add quantities.

Thank you in advance for your time,
