Matt, This is a long shot, as I'm no reports guy, let alone Business Objects.... But have you tried using a lookup parameter instead of a straight boolean? Eg, use "Portlet Yes/No" rather than "CMN_YesNo" as the lookup for a reporting parameter, rather than a straight boolean, since the portlet lookup returns 1/0 for yes/no, rather than 4039/4040 from the common lookup... I suppose that you have checked for the values "behind the scenes" on the parameters right? Maybe someone else has a better idea, as I'm suggesting blind here... Sam.
