7. Select “Edit…”
8. Select “=Fields!Customer_Name.Value” in “Document map label”
9. Select “OK”
10. Navigate to “Navigation” Tab
11. Enter “Customer” or what you want the title to be in the Document List
12. Select “OK”
13. Save and import RDLC changes, and then compile report in Classic client.

Notice the expand in the top left corner. Unfortunately this does not display anything in NAV 2009 RTM, this will be fixed in SP1.
16. Click the expand button to see the Document Map
17. Now click the customer “Klubben” and notice that the report in to the right navigates to the area where info about the customer “Klubben” is displayed.
