You could create a Calculated Field within the Pivot Table. Just click on
the drop down list in the Pivot Table Toolbar Formulas Calculated Field.
Name it whatever you like and make it equal to the column for 2008 sales
minus the column for 2007 sales. Hope this helps.

The pivot table gives the total of columns by default. But I need to see the
difference of one column over the other (in value or percentage), e.g. the
growth of sales in 2008 over 2007. Can I do it without having to copy the
data on a new sheet and doing it in Excel?
