In Nettailer a unique product is identified as Manufacturer Name + Manufacturer Part Number + Product condition and for each combination, the shop creates and maintain a unique product/product-id.
During the product imports Nettailer has a setup to uniform the Manufacturer's Name so for example HP isn’t used in 10 different variations from the active suppliers.
This product alignment aims to have only unique products created where several suppliers are connected.
If the suppliers use incorrect or deviant part numbers, Nettailer cannot identify products as the same and will therefore not be able to group them as one.
The combination of Manufacturer Name + Manufacturer Part Number is subsequently used for matching 1WS/CNET product content.
