Note: One source table column is not only added for one time under the class panel, it can be added for any number of times based on Business needs.
If report requirement is to display summary totals of amount_sold and also average total of amount_sold, add amount_sold for two times as an Object in a class. For the first Object add the qualification Measure with the function Sum. For the second Object add the qualification Measure with the function Average.
