You can add children to nodes in hierarchies, either as part of creating a new hierarchy or for updating an existing hierarchy. You create a new relationship between the parent and the child that you enter.
The relationship role describes the role of the child, or object party, with respect to the parent. For example, if Vision is the parent, you can enter Subsidiary for the role and Vision2 for the object party to create this hierarchical corporate relationship: Vision2 is a subsidiary of Vision.
The selected hierarchy type determines the available roles, and the selected role determines the type of party for the object. For example, if the Subsidiary role is defined so that only an organization can be a subsidiary, then only organizations are available as the object party.
Note: You can use only existing parties as parent and child. Duplicate prevention, therefore, does not apply to creating relationships through a hierarchy.
