Primavera P6 Web Access; Reports run from dashboard portlet won't populate with data

I had created four reports using the Reports Wizard in P6 Client Release 7 to assist with resource leveling.  When run from the client application, the reports populate with data as expected.  Our database administrator made these reports available to me in P6 Web access and I added them to my dashboard portlet but when I attempt to run any of the reports from the portlet, no errors appear but the reports are empty, only the header rows appear.   Any suggestions?
