we have a web shop with around 9000 products. to a lot of these products you have to assign cross selling products.
that is the procedure:
you get an excel list with all shop products (name, unique product number)
1: go to [url removed, login to view]
1a: search for the product (unique product number)
1b: you get a list with the main product and all cross selling products, which belongs to the main product
2: call the backend of shop [url removed, login to view]
2a: go to your main products sheet
2b: assign cross selling products (which you can choose from a list)
a lot of products don't have cross selling products. there is nothing to do.
notice, that both sites are written in german.
