| `regionCode` | String | Optional | Region code - See [getRegionList](/docs/en/compute-vserver-server-common-getregionlist). - First Region in the query results (default). |
| `autoScalingGroupNo` | String | Required | Auto Scaling Group number - See [getAutoScalingGroupList](/docs/en/compute-vautoscaling-autoscalinggroup-getautoscalinggrouplist). |
| `scheduledActionNo` | String | Conditional | Schedule number - See [getScheduledActionList](/docs/en/compute-vautoscaling-autoscalinggroup-getscheduledactionlist). - Not entered during schedule creation - Either `scheduledActionNo` or `scheduledActionName` is required when editing a schedule. |
