When selling on amazon the internal wawi articlenumber is of little importance. It is all about the ASIN. In some 'views' you can change so that the ASIN is also visible but far from all. Not when making an purchase order. Not in 'Ware im streckenlager'. Not in the customer order. And so on and son. I always need to doublecheck via articlenumber. ASIN is king when selling on amazon.
