how to generate the traceability report between DNG and DM using link type "Derives Architecture Elemenr"

RMM/Rhapsody does not yet contribute information to LQE (that functionality is in beta in 7.0.2), so you need to use RPE to produce traceability reports that include RMM/Rhapsody artifacts.
Links to model elements will be available under DerivedLink. Did you try using dataSource/artifact/traceability/links/DerivedLink/relation ?
