Destination Tree displays Destination Requirements of the requirement by Tree.
Source Tree displays Source Requirements of the requirement by Tree.
When there are more than one Source Requirements in Destination Tree or more than one Destination Requirements in Source Tree, the same requirement is shown many times in both cases.
Both Trees are useful for grasping whole picture of the relationship between requirements.
When the relationships are circulated as the following Relationship Map, RaQuest shows the Tree as described below. RaQuest shows a red circle at the upper right of the requirement icon displayed twice in the circulation.
