Chapter 5. Creating Data Reports > Creating Summary Layout Parts

Creating Summary Layout Parts

Once you have a found set, you can summarize it in a variety of ways. Using summary fields, you can count how many records were found and print the count in a report. You can create totals, averages, minimums and maximums of number fields. If you are statistically inclined you can even create standard deviations.

Layouts with summary fields require a little more planning than those without them. A summary field is unique in that the same field will display different values, even in the same layout, depending on which part it appears in. A summary field defined as a total in the Trailing Grand Summary will display the total of that field for the entire found set. But the same field in the sub-summary layout part will only display the total for the sub-summary field.
