Unlike the analysis created from Analysis wizard where users can easily change measures(Refer Section Changing the measure of an analysis), in advance analysis, users can change measures by going into the properties of the cross-tab.
In your created advanced analysis(Refer Section Creating an analysis using Advanced option) , click on Properties.
A pop-up will appear. In the row tab, select the row variable for which you wish to change/apply another measure and click on Measure.
A drop-down will appear. Select the required measure(s) you wish to view for your analysis and click on Set.
All the measures will get applied to the analysis and the scores will be displayed accordingly.
