Calculated Controls

Calculated fields in a report show percentages and display currency. These fields can display the value of each detail line as a percentage of the report total. You can apply currency formatting to financial fields. It is useful when you want to show formatting relevant to your report.

For example, in a financial report for an organisation, sales figures can be represented by percentages of the annual revenue. Currency formatting can be applied to display sales totals in a chosen currency.
