Displaying grand totals for rows in cross tables
You can display grand totals for each row in the cross table. Grand totals are by default calculated using the same expression that is used for calculating the cell values. For example, a grand total can indicate a 'grand sum' or a 'grand average'.
About this task

Note: There is, however,
an
option to base a total on the already aggregated
cell values in the cross table. If you use this option, the total will
be calculated as the sum of the cell values, no matter expression used for the
calculations of the cell values.
