A user can click items in the document map to jump to areas within a report.
In Design view, right click outside the report sections, select View and open up the Group Explorer.
Select a report group to which you want to add a document map. The properties for the selected group appear in the Properties pane.
In the DocumentMapText property, type the text that you want to appear in the document map. Alternatively, click the ellipsis to open the Expression dialog box to specify an expression that evaluates to a text. Typically for a group, the expression you type should match the group expression.
Repeat steps 1-4 for every group that you want to appear in the document map.
Run the report - the document map displays the group values. Click any document map node to jump to the report page with that item.
