In Qlikview while doing the data model we should try to get the star schema so that the performance of the application is more. So if you have mulitple fact tables then try to make that as a single table either by joining or concatinating. And for dimensions based on the requirement join those dimensions individually to the fact table. hope this helps . If you have any problem while doing the data model try to post us a sample application so that we can help you with that.
