Column or row totals added to the OLAPQuery section are aggregates and can be recalculated using data functions. When applied to totals, data functions apply the calculation to surface values.
When applied to surface values, data functions recalculate the values in the visible cells or surface of the OLAPQuery section. For example, you can show the total sale, average sale, and maximum sale of each product by quarter. Each of these dimensions is based on the same value. They only differ in the data function that is applied.
To apply a total function:
Choose OLAP, then Data Function and then select a function.
The following table lists the data functions available in the OLAPQuery section.
