This cleansing rule uses AI-supported category mapping (AI Smart Classification). For catalogs which were created via iPIM SSP, a cleansing rule of this type is set up automatically. At the same time an attribute mapping for the attribute “IPIM_PURCHASE_CATEGORY” is also added. This attribute indicates the classification of items resp. their parent products, meaning to which categories of the iPIM primary taxonomy they belong. The cleansing rule effects that for each imported item, the attribute is assigned the corresponding value for their classification in order to map them to the respective categories. Hereby, the category mapping is based on the supplier attribute which was specified as the categerorizing attribute in the catalog creation process of iPIM SSP.
