Working with Aggregate Data

Aggregating data involves performing a calculation over a set of data rows. For example, in a report that has a column to calculate price*quantity, you can take the sum of all those calculations to obtain the total price of all items. You can create up to three aggregations for a calculated column.

When you aggregate data, you choose whether the aggregation appears in the table header or footer. If the column is a detail column in a data group, you can display the aggregate value in the group header or footer. Figure 13-39shows aggregate data in a group footer.
