Provides a reference to a notification field defined in the /NotificationClasses/NotificationClass/Schema/Fields section of the application definition file (ADF) that can be used to supply a protocol field value.
<NotificationClasses> <NotificationClass> ... <Protocols> <Protocol> ... <Fields> <Field> ... <FieldReference>
|Data Type||string, between 1 and 128 characters in length.|
|Occurrence||Optional once per /NotificationClasses/NotificationClass/Protocols/Protocol/Fields/Field node.|
|Updates||Can be modified, but not added or deleted, using NSControl Update.|
|Parent Node||<Field> Node (/Protocol/Fields)|
If you update a <FieldReference> element, NSControl Update 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.
Important If you update a <FieldReference> element, any data existing in the original SQL Server tables is permanently deleted.
Important If a <FieldReference> element is not included in the <Field> node, a <SqlExpression> element must be provided instead.</
