When an account establishes a trust relationship between itself and your account, you become a delegated party. You and all the users you have authorized can switch to the delegating account and manage resources under the account based on assigned permissions.
The user created in 3 of Assigning Permissions to a User (by a Delegated Party) can switch roles to manage resources for the delegating party.
If an agency other than the agencies created by the delegating party is displayed, it indicates that you do not have access permissions. Select the correct agency in the Agency Name drop-down list.
