If there is a need for grand totals and no grouping in the project, DynamicJasper provides a way to get that.

Grand totals can be located in the header or the footer of the report

DynamicReportBuilder drb = new DynamicReportBuilder();
//ReportBuilder initialization

drb.addGlobalHeaderVariable(columnAmount, ColumnsGroupVariableOperation.SUM);

drb.addGlobalFooterVariable(columnAmount, ColumnsGroupVariableOperation.SUM);

Where the parameters passed are:

• The column to use for the calculation
• The operation to apply (SUM, COUNT, etc)
• The style to use for this total (optional)Refer to GroupsReportTest for a working example.
