Creating sections lets you split report information into smaller, more comprehensible parts.
Grouping quarterly revenue results into sections on a report
You are the regional sales manager in Texas. You receive a report showing 2003 annual revenue for stores in your region, broken down by cities and quarters.
You want to make a comparison of the results for each city per quarter. You set [Quarter] as a section value, so that the report is broken up into four separate sections by quarter.
You can create a single section or include multiple sections with subsections in a report. You can also remove and reposition sections within a report.
