I have a pivot table with the sales of 100 different products over a ten year period. The sales for each year are in a different column in the table that's being used so that when I make the pivot table I can put 2010 vs 2011 next to each other. Now is there anyway to create a column next to those two to show what the sales difference is between the two years? I'd like to be able to compare different years of data for the 100 products while being able to filter the data to look at different criteria. Is there a way for this the way I have the data set up or is there a better way to have the data that the pivot table is pulling from to be able to create this?
thanks.
thanks.
