Extend service_attribute_x to BE variants #283
Description
When defining shipping costs, an amount can be specified as the value 'service_attributeX' depending on the information provided (e.g. in grams) and calculated as the total weight using the function 'by_service_attribute_X_sum'.
It would be great to extend this option to BE variants.
Example: For food items, I have created BE variants by weight (500g, 750g, 1000g), which of course have different weights – but the 'service_attributeX' field is only available for the 'main' product, not for the BE variants.
PS: I have been working with cart/cart_products for many years and use it for small/medium-sized shop systems. I am very satisfied – great job!
