Summarizing data in the Active Report output
You can add an output summary to a list or crosstab control that reflects the data that appears in the control when an active report is viewed.
About this task
You can add two types of summaries to an active report: regular summaries and output summaries. Regular summaries are available to all reports while output summaries are available only to active reports. When you add summaries to a report, you can aggregate large quantities of data and identify significances in the combined value. For example, if you want to calculate the voter turnout of a specific region, rather than count individual votes, you can aggregate the total votes received by each candidate.
