These relationship types are not ranked, nor are they necessarily related to each other. They are merely relationship types that are grouped together for ease of classification and identification. The same relationship type can be associated with multiple hierarchies. A hierarchy type is a logical classification of hierarchies.

You configure the following properties when you create a hierarchy type:

Field	Description
Code	Unique code name of the hierarchy. Can be used as a foreign key from Hierarchy Manager relationship base objects. You cannot change the code after you create the hierarchy type.
Display name	Name of this hierarchy as it will be displayed in the Hub Console .
Description	Description of this hierarchy.

When you first create the hierarchy type, the hierarchy type does not have any references. The Hierarchy tool populates the hierarchy type references with entity types, relationship types, and profiles when you associate relationship types with the hierarchy type that you created.
