Report Column

The Report Column field on the Summary tab will contain only those fields that are of a numeric data type that were selected to be included in the current ad hoc report.  

For each displayed field, you have the option of including one of the following aggregate functions; sum, avg, min or max.  When checking one or more of these checkboxes, one or more new values will be displayed along the bottom of that column in the ad hoc report output.
