I'm trying to add two calculated fields to a pivot tabe. I'd prefer that the
field calculation the takes a row item quantity or dollar figure and
calculates the item as a percentage of the total. Such as region xx has 85%
of the total sales units but only 78% of the total sales dollars. Can anyone
help me?
