Base Hierarchy

transaction code: COMM_PRAPPLCAT.

hierarchies maintained here will be treated as 'Base Hierarchy', you can assign different base hierarchy for each product type.

Important:

only base hierarchy can be assigned with standard set type(delivered by SAP)

if you assign standard set type to a non-base hierarchy, Error message: Certain set types can only be assigned to the base categories Message no. COM_PRCAT095 will show up.

A product must be assigned at least to one category from the base hierarchy(base hierarchy for the specific product type)

when you create a new product, for the category field you must fill in a 'base category'. *any category from a base hierarchy is called a 'base category', afterwards you can assign any non-base categories as you wish.
