I'm trying to write a custom policy to prevent all kind of users from creating the subscription directly under the Tenant level. Rather, the subscriptions should only be created under the Management group level.
Tried multiple ways in authoring and testing the poicy but had no luck.
Any help would be highly appreciated.
I tried multiple combinations with the following Aliases targeting to Root Management group and Tenant "Microsoft.Subscription/subscriptions", "Microsoft.Resources/subscriptions"
but not able to make it functional.
