An Azure relational database service.
Hello,
The reason for this issue can be the user with which you are trying to run the database provisioning does not have the 'sysadmin' privilege. If you logged in as domain admin user, domain admin user does not have the 'sysadmin' privilege by default.
To grant 'sysadmin' privilege, connect SSMS and give the 'sysadmin' privilege to the user. Only a database administrator can give 'sysadmin' privilege to other users
