Defining Summary Calculations
By default, a matrix report counts the number of records that match the criteria defined by the column and row fields. To use a different calculation, select a function from the picklist in the cell. When choosing a summary calculation other than Count, select a numeric, date, or ID field on which to perform the calculation. You must add grouped rows to your report before adding summary calculations.
