I have three different sources which I get as QVX file( Source1.qvx source2.qvx source3.qvx). Im directly importing this qvx files into the qlikview.In these three sources I have common variables Year, Month , Day. Since Source1 is my main data. I created a drop down the qlikview for user selection. I’m looking for global variable when user selects year , month, day from the source1 the selection must be pass as parameters(year, Mon,Day) to source2 and source3 inputs. Could you help me how to achieve this.
