Interactive Data And Clickthrough Reports

My reports are not allowing me to "Clickthrough" to more detailed reports.



I want my report to automatically show a detail record when they select some "interactive data" in my reports.



I have read a page on this stuff ( http://msdn2.microsoft.com/en-us/library/ms345252.aspx ) which states:



In Report Builder, a clickthrough report is a report that provides detailed information about the data contained within the main report. A clickthrough report is displayed when the Report Builder user clicks the interactive data that appears in the main report. These reports are automatically generated by the report server. You, as the model designer, determine what is displayed in clickthrough reports by setting the DefaultDetailAttribute and DefaultAggregateAttribute properties that you assign to an entity in the report model.



Hence, within my report model i have created an entity with a number of DefaultDetailAttributes.

I have not created a specific "click through" report as i would be happy to view the automatically generated report that should contain the attributes defined in the "DefaultDetailAttributes" list.



However, when i view the report, no data items are links (or "interactive data" as the msdn article describe them).



Has anyone got any ideas on how to make the report data interactive?



Thanks,

pete
