Hi Rashmi,     for the direct fta event, representing the failure mode you can create a Derived Property:     And choose OCL:     (self.element.oclAsType(safetyModel::Failure)).mediniGetOpposites('represents')->      select(c|c.oclIsTypeOf(FTA::Event)).oclAsType(FTA::Event)->reject(e:FTA::Event| ( e.mediniGetOpposites('analyzedEvents')->size() >0))     This should solve already part of the visualisation. Can you please confirm?        For the second part: you want to see the Malfunctions on a higher level? Which level exactly? What happens, when below the malfunction there is another malfunction as well? What about when there is no malfunciton in the fault tree? Do like to see the hazrard?     In  other words? what is the sense of the display of one or many malfunctions in the FMEDA?
