You send your feed in synchronization mode, you get an error in the report, such as this one:
Message: 1 Error 8560: SKU: XXX-YYY, Missing Attributes product_type. SKU XXX-YYY does not match any ASIN. Creation of a new ASIN requires the following missing attributes: product_type. Feed ID: 0. For details, see http://sellercentral.amazon.es/gp/errorcode/200692370
The module has two modes, a Synchronization Mode to synchronize inventory and Creation Mode to create a non-existent product.
In Synchronization Mode the orders are sent in matching mode, i.e. the product will update your stock if the order exists and if it does not exist the module will try to create an offer on the basis of an identical product that might exist on Amazon.
However, if the product does not exist, you get this error message in the report.
The procedure to follow is then to create the non-existent product on Amazon using the Creation Mode. Follow the steps for Creation Mode.
