The seller SKU for a product used with Amazon to uniquely identify it stored on the AmazonProfile of that product. Oscar’s stock record in the partner app also provides a SKU that is used with a Partner corresponding to a seller/merchant ID with MWS. In most cases, you would want the partner SKU on the StockRecord kept in sync with the SKU on the AmazonProfile.
