Assume I have more than 100 different variation products and all of them share same fields ( such as commission rate, Brand, Weight and etc). As I understood so far, I need to create 100 product variation first.
Now, my question is:
Do I need to add each of these fields for each variation separately? or is there any way to add them only one? e.g how can I add these fields to the product entity so that every time I create a variation, it automatically adds all these fields, similar to sku and price?
p.s: I use commerce_kickstart-7.x-2.40
Any help will be highly appreciated!
