Linear calculations are worksheet calculations that Discoverer aggregates by simply adding up a series of data points. For example, in the crosstab worksheet below Discoverer adds up the Profit Sum and Sales Sum for Chicago and Louisville to create aggregated values for the Central region (i.e. $49,246, $77,668).
Non-linear calculations are worksheet calculations that Discoverer aggregates by adding up data points and applying the calculation to the result. For example, in the crosstab worksheet below Discoverer calculates the aggregated value for the Sales Margin item by applying the calculation 'Profit Sum/Sales SUM' to the aggregated values for Profit Sum and Sales Sum. In other words Discoverer calculates the aggregated value for the Sales Margin item for the Central region as 0.634 (i.e. 49,246/77,668), not as 1.322 (i.e. 0.708 + 0.614).
