Permission problem accessing Tabular Model

Hello;

I'm hoping this is the proper forum for this post - If not I appologize in advance.

I created a PerformancePoint Dashboard and deployed it to a SharePoint 2010 site. It is based on a Tabular Model that lives on SQL Server 2012BI.

In Dashboard Designer I see everything perfectly well. When I try to open the dashboard in SharePoint I get a message saying "You do not have permissions to see this data"

SQL Server Profiler says "The restriction value provided by the consumer either does not match other restrictions or refers to an unknown object."

The Role that I have defined in my model has Read access to the model. That Role is also defined as the role used to access the Dashboard's DataSource. I can tell by the Profiler Trace that it is indeed using the proper Role and the proper User Name.

Any ideas as to where I should be looking and what I should be looking for?

Any and all help would be greatly appreciated.

Thanks in advance.

Ron...
