I am looking for a way to get the product type to the packing slip items. Due to our fulfilment they like to have these shown to know faster what to search.
I tried & read a lot about line_item. attributes but the product type seems not to exist. While searching I just found something like item.product.type but this does not work in a packing slip line_item environment.
Perhaps you guys here have an idea to referre to the product type within the line_item on a packing slip.
