Here you can determine how sub-totals and totals are to be handled within the report.
You will first indicate the fields that cause totals to occur (such as on change of client). Select each field in turn at the next blank entry and use the arrow buttons to set the priority of each total level (such as project within client).
If you select at least two levels of grouped data, you will, at the Chart tab, be able to specify the ability to drill down into lower level groupings for a chart report type with a widget usage type.
For all entries where a total is to occur, the fields that contain values are listed. In each case, indicate the type of total that is required. For a Chart type of report, you cannot choose Minimum, Maximum or Average.
Where an entry is a numeric value, check the Cumulative box to accumulate values across the report columns.
