Map Report Parameters to External Variables

For example you can map Session.UserID or Cookie.UserID to a report parameter UserID and hide the user prompt for that parameter. The value of the parameter is passed behind the scene by RSReports custom viewer. This is useful when you have a portal and your data is genreated based on the type of user who is looking at it. You can build reports specific to users companies, or contain their name and address without prompting them for a ClientID or UserName. You can map report parameters to: Session variables. Application variables. Server variables. Cookies. Membership Profile. Other environment variables: UserID, PortalID
