 * `display_name` - (Required) The display name which should be used for this Cost Anomaly Alert.
 
+* `subscription_id` - The ID of the Subscription this Cost Anomaly Alert is scoped to. Changing this forces a new resource to be created. When not supplied this defaults to the subscription configured in the provider.
