This flag is used to determine whether shipment reference numbers should be copied when shipments are duplicated. It must be False if either the Auto-Generate Only flag or the Enforce Uniqueness flag is True.
When duplicating a Shipment, all the Shipment/ Container/ Item Reference Numbers for that Shipment and for its Containers/ Items will be duplicated if the corresponding Reference Number Qualifier is configured with Duplicate Enabled set to True.
When the Reference Numbers page is accessed from the Shipment Summary page in Duplicate Mode, all Reference Numbers that qualified for duplication will be presented with the appropriate copied values. User will be allowed to override these Reference Numbers.
