English term (edited): decreased warp change-outs and warp sku's

http://en.wikipedia.org/wiki/Stock_Keeping_Unit

Every product is assigned an SKU by the merchant (as opposed to an EAN which is assigned by the manufacturer). This SKU is then used to order, locate and manage the inventory of a product. Each product and variant of a product has a different SKU, for example different flavours or models of product have independent SKUs.
