A grand total is a value that is composed by adding together other total amounts (subtotals) of the row/column.
When creating a report, you can change the default way grand totals and subtotals are displayed on the grid. The available options are:
grid.showTotals
property of the Options Object:report: { options: { grid: { showTotals: "off" } } }
grid.showGrandTotals
property of the Options Object:report: { options: { grid: { showGrandTotals: "rows" } } }
grid.showTotals
and grid.showGrandTotals
options for all reports.
Hide grand totals from the entire report:
Hide grand totals from the rows:
The layout of subtotals is changed similarly.
