I've around 19.000 products/variants in Shopify. All the 19.000 variants i've created in Shopify have no SKUs. I've created all variants in Navision with unique SKUs and now I need to add the SKUs from NAV to the 19.000 variants in Shopify. The product titles is not the same in Nav and Shopify, so there is really nothing that connects the products from Nav and Shopify.
Do I need to manuel copy paste the SKUs from NAV to Shopify or is there a is there an easier way?
