- DeliveryChannelName
- DeliveryStatusCode
- DeviceAddress
- DeviceName
- DeviceTypeName
- DistributorWorkItemId
- ExpirationTime
- LinkNotificationId
- NotificationId
- NotificationBatchId
- SentTime

| If you update a FieldName element, updating the application deletes and re-creates the notification class to which it corresponds. This includes dropping and re-creating the SQL Server tables used by this notification class. Any data existing in the original notification class tables is permanently deleted. |
