Notes and Constraints

Before using Organizations, you need to enable Enterprise Center. For details, see Enabling Enterprise Center.
You can only use the master account of the Enterprise Center to create an organization.
The management account of an organization cannot invite accounts of a different type to join the organization. For example, the management account registered with the Huawei Cloud Chinese Mainland website cannot invite any accounts from the Huawei Cloud International website to join its organization, and vice versa.
