Organizing records into logical groups often makes them easier to read and understand. For example, you could group a sales report by the date field to quickly see how many sales occurred in a particular month.
You can also group and sort your report data using the Group, Sort, and Total pane. Using the pane allows you to add multiple levels of grouping and sorts.
Access displays the Group, Sort and Total pane at the bottom of the screen. Here you'll see any fields that are currently being used for sorting or grouping your report.
