List products without displays using views
I'm using Drupal commerce with commerce backoffice module to improve backoffice management.
It works pretty well, but there is one feature I need and I didn't find how to do it.
On the All products variation views (so a commerce product view), I need to create a filter that allow to list all products that are not associated with a product display.
How can I do that using views filters ? I tried a lot of different combination, relationship etc... but couldn't find a way to do this.
