A very simple computed item can be created using a Label dimension and the values from the Fact Detail cells. As an example of computed item display, consider the original simple "Units Sold" Pivot display below:
Several computed item columns can be added to this Pivot using the "Units Sold" Facts as a source of input data. These computed items are shown below as new columns to the right of the "Units Sold" column (surface values have been disabled in this example):
These new Computed Item columns are evaluated as follows:
Units Sold * 2 = Units Sold values multiplied by 2 (i.e. computed item calculation: formula is: Units_Sold * 2)
Sqrt Units Sold = Square root of Units Sold values (i.e. computed item calculation formula: Sqrt (Units_Sold) )
ColMax Units Sold = Maximum value of Units Sold in a column (i.e. computed item calculation formula: ColMax (Units_Sold) )
Average Units Sold = Average value of Units Sold (i.e. computed item calculation formula: Avg (Units_Sold) )
