Creating a Document Map
This is a simple navigation feature that allows the user to find a group label or item value in the report
by using a tree displayed along the left side of the report. It's sort of like a table of contents for report
items, which can be used to quickly navigate to a specific area of a large report. You typically will want
to include only group-level fields in the document map rather than including the detail rows.
The document map is limited to the HTML, Excel, and PDF rendering formats. In Excel and HTML
formats, the document map may not survive when saving report files to an older document format, such
as Pocket Excel on a Pocket PC device.
This example will use a version of the drill-down report, only with the visibility properties set back to
defaults. You will add the CategoryName and SubCategoryName groupings to the document map. In
the Grouping and Sorting Properties dialog for the Category row (group 1), drop down the Document
map label list, and choose the =Fields!CategoryName.Value item (see Figure 6-37).
