Crystal Reports for Rational Application Developer Designer Guide
Do you want to summarize the
data?
Do you want to total, average, count, or
determine the maximum or minimum value included in all the values in any column
on the report?
Crystal Reports allows you to do
this, and it also allows the grand total (or the grand total average, grand
total count, and so on) to be placed at the bottom of the selected column. For
more information, see
Calculating Percentages and
Selecting top or bottom N groups or percentages .
