Show Values as a Percentage
You can show values as a percentage or share
of a crosstab total to quickly compare the contribution of an item
to the whole.
If the crosstab contains a user-defined arithmetic calculation, such as addition, subtraction, multiplication, or division, IBM® Cognos® Analysis Studio computes the arithmetic calculation first, then applies the % of base calculation when you show values as a percentage. This is also true with exponentiation and rollup calculations.
If the crosstab contains a user-defined percentage calculation, such as percent, percent growth, percent of base, or accumulated percent, there is no change when you show values as a percentage. This is also true with statistical calculations, such as mean or standard deviation, and ranking calculations, such as rank or quartile.
