A record can have relationships to other records. When the Hierarchy Manager is enabled, you can view a graph that shows how a record is related to other records.
You use the
Hierarchy
view to investigate relationships. You can view hierarchical relationships, such as an employer-employee relationship, as well as relationships that are not hierarchical, such as peer relationships.
If your MDM administrator created a custom view for this purpose, the name of the view might be different.
