Understanding the Do Section and Column Inclusion Events

The most common event for a group or columnar section is the Do Section event. When a group or columnar section is processing data, the Do Section event occurs after each record is fetched.

The most common event for a tabular section is the Column Inclusion event. Because of the automatic totaling on a level break, tabular sections are processed differently. In a tabular section, the Do Section event is processed only at each level break. Therefore, the Column Inclusion even is used in a tabular section to process the data after each record is fetched, rather than waiting until the level break.

Regardless of the section type, do not use the Column Inclusion event when you are performing a calculation between columns (such as when calculating variances) or between variables within a column. For these situations, use the Do Section event.

When using the Column Inclusion event, you attach event rules to individual columns in the section.
