Hi
I used a custom list app to display the feature level dependency.
1. Add a custom list
2. Select Type portfolio item feature
3. Add Query -
(((Release.StartDate <= today) AND (Release.Date >= today)) AND ((Predecessors.ObjectID != null) OR (Successors.ObjectID != null)))
On this list select column "Dependencies" to display dependency
Hope this help.
