When you group a layout by data item, you can easily "roll up" activity data to calculate group totals and simplify the data presentation. Click the plus (+) or minus (-) symbols to the left of any grouping band to expand or collapse information, or right-click in the layout and choose Expand All or Collapse All. You can also double-click grouping bands to show or hide details.
To show both group totals and detailed information for reporting, you can collapse or expand individual groups and then show a grand total at the top of the layout.
Note
- The Summary Service also enables you to summarize project-level values and store them in the database for analysis and reporting across the enterprise.
