Hi - creating a QVD in qlikview is probably as easy as any method. The other current alternative is to switch QLik Sense to run in 'legacy mode' . Then you can copy your load script (that you still generate in qlikview) into qlik sense and qlik sense can then correct directly to sap.
direct SAP connectivity through 'standard mode' will soon be available in qlik sense. look for updates in community.
