Each RoutingItem object has an Item property which points to the relevant question in the MDM document's Fields collection. For questions in the Fields collection, the Dummy property (in the QC context) is relevant to the mrRoutingScript MDSC.

This property indicates that the question is not to be asked, and is set to True when the "Hide this question" option in the Build activity is set to Yes. If the value of this property is True, the mrRoutingScript MDSC does not generate an Ask statement for the question.
