How Do I Resolve Error "Insufficient permissions. Add corresponding fine-grained permissions"?

During the migration, you received error message "SMS.0204 Insufficient permissions. Cause: xxx. Please add corresponding fine-grained permissions."

Using SMS requires that you have permissions for ECS, VPC, IMS and EVS, or the migration will fail.

Obtain all required fine-grained permissions and try again. For details, see Creating a User and Granting Permissions.
