Creating an Account Hierarchy in Siebel Communications (End User)
Creating an account hierarchy includes creating child accounts and associating them with a parent account. You must create the parent account before adding child accounts. For information about creating an account, see Creating an Account in Siebel Communications (End User).
Note: For mergers or acquisitions, end users can move the entire hierarchy
under a new account. Be sure to associate the new parent account with
the first (top) level. The new parent ID automatically cascades to
its child accounts, reflecting the change. For more information, see Changing a Parent-Child Account Relationship.
