Now, you can build a report tree for the Global Sales report with sub-totals by region (Asia, Europe, and Americas) and, for each region, the sales for Sales Automotive and Sales Packaging.

The higher levels in the report hierarchy automatically represent the sum of the underlying details, but, in some cases, special calculations are required. For the calculations, you can create report analysis codes of type Calculation. Calculation analysis codes let you define calculations using other analysis codes as components.

Addition, subtraction, percentages, and ratios are typical calculations.
