When you click an item in the document map, the viewer jumps to that item in the report.

A document map functions as a table of contents and provides a convenient way to navigate a lengthy report.

In a Page or an RDLX report, you can add report controls, data regions, groups and detail groups to the document map by:

• Assigning a value to the Document map label on the Navigation page of the corresponding dialog.
• Setting the value of the Label property in the properties window.
• Setting the value of the HeadingLevel property in the properties window.

Viewing the Document Map

   If there is no document map associated with the report, the button does not appear at the bottom of the sidebar pane.
3. In the Document map that appears, click the item you want to view in the report.
