Creates an organizational unit (OU) within a root or parent OU. An OU is
a container for accounts that enables you to organize your accounts to
apply policies according to your business requirements. The number of
levels deep that you can nest OUs is dependent upon the policy types
enabled for that root. For service control policies, the limit is five.
For more information about OUs, see Managing Organizational Units
in the AWS Organizations User Guide.
If the request includes tags, then the requester must have the
organizations:TagResource
permission.
This operation can be called only from the organization's management
account.
