Symptoms

Missing properties under the smartobject during the configuration of the "transfer data" rule when trying to transfer a value between multiple views' smartobject. This happens for a few of the views that share the same smartobject.
 

Diagnoses

The "missing properties" were not added to the design time view as input was not needed.
 

Resolution

This was resolved during the session by adding the "missing" properties to the affected views in design time. After doing so, the properties now appear under the smartobject during the mapping process when configuring the "transfer data" rule.
