In the example shown in Figure A–1, assume you need to create an SPA for the provider organization named VIS. You could assign the SPA role to user1 in the organization DEF.
The SPA must reside in a subordinate organization because a provider organization node does not contain any users.
Thus, before a provider organization can be managed by an SPA, at least one organization must be created under it. This organization should be designated to hold users who are assigned the SPA role. For more information, see Creating a Provider Organization and Service Provider Administrator.
