The base hierarchy used either for products in general or for specific product types.
A product can be assigned any number of categories. However, when you first create a product you must assign it to a base category. A base category is a category belonging to the base hierarchy, which is the basic hierarchy defined for products in general or for a specific product type.
Within the product master, assigning a hierarchy to the application Product
enables
it to be used as a base hierarchy, which is required to create products. Each
product created must be assigned to a category from this hierarchy. It is
the starting point when you create a product.
You assign product hierarchies to applications in Customizing for Cross-Application
Components
, by choosing :
You can assign a base hierarchy to a specific product type. This overrides the higher-level assignment between the hierarchy and application.
If a base hierarchy is not assigned to a product type, the hierarchy specified for the application serves as the base hierarchy for all product types.
The base category assigned to a product determines the product IDs allowed when a product is created.
You define the number ranges for internal and external number assignment
in Customizing for Cross-Application Components
,
by choosing /Define Number Ranges for the Product Type

The main base hierarchy generally replicated from SAP
ECC is the base hierarchy for Material

The report CRM_PR_FIN_CREATE_HIERARCHY is used to create a base
hierarchy for the product type Financing
.
Base hierarchy for the product type Intellectual
Property
Base hierarchy for the product type Warranty
Base hierarchy for the product type Service
If you are creating service products in SAP CRM and not replicating them from SAP ECC, do not use the hierarchy R3PRODSTYP as the base hierarchy for services, but create a new hierarchy in SAP CRM.
