I want to change a lot of Internal reference codes of my Product Variants.
But i am getting this error: (Also on runbot with demo data)
To reproduce:
Go to Inventory/Product Variants
Select all, action/export, check' i want to update data'
Keep defaults.
Edit a few fields like the internal reference of a few products in the xlsx file
Upload the file again via Favorites/ Import records /Upload the xslx and then Test.
What am I doing wrong ?
