Google Feed pulling Custom SKU instead of Manufact. SKU
In our store, which is both brick-and-mortar and online, we use the Custom SKU field to create our tag labels, which are our own and have no relationship to manufacturer's part numbers or gtins. Google is pulling this Custom SKU tag label as the manufacturer's part number (mpn). How can I get the Google feed to reference the Manufact. SKU (Which is where we place the mpn) for this value? I've tried using the variables "product.code," "product.sku," "variable.code," and "variable.sku," all to no avail. Merchant center is still showing our Custom SKU tag labels in the mpn field. I really want to do this through the feed itself without having to upload a supplementary feed.
