Commerce line item views with fields from content node I have some fields on content node (not on product variation)
like images, brand, and others that i want to show up in cart/order views
on edit view in advance>relationship, you can add product refference and that enables the option to add fields from product variations, but i cant find a way to add fields that are on the content node

In less words: i want to add fileds like image that are on the content type to cart/order views.

Found a good work around:

adding relationship you can obtain fields from product in views.
This isn't easy, because the line item has no direct reference to the node. It does store the node URL in a textfield, but that does not a Views reference make. If you have a store where there's only one product display referencing each product, then you can get away with using a reverse product reference - i.e. starting with the line item, you reference the product, and from the product, you add a reverse reference to the "node referencing the product." Then you should be able to add fields from the product display node.

If you have multiple product displays referencing any given product, this solution might not work (unless of course each node contained the same fields you intend to pull into the View).
