I am trying to use the Pivot Table Options\Show column Grant Total feature to display Sum on certain columns and Average on other columns. In the attached example you see columns 2,4 have Grand Total set to Sum, Column 3,5 the Pivot table Value field settings are set to 'Summarize value field by Average'. Column 3 is correct, but column 5 is displaying Sum instead of Average. Note that Column 5 is a calculated field that uses the formula source_data/100 so that I can display it as a percent %
How can I display the average value for column 5 in the Grand Total row?
