I currently am using PPT to expose data from a Microsoft Analysis Server cube. The cube is wide open and requires no permissions to access.

The behavior of my filters is odd as sometimes they work perfectly fine, and other times I receive the following error upon report run:

Unable to get filter values.
An unexpected error occurred. Error 10828. Additional details have been logged for your administrator.

I have looked at the ULS logs and found the following:

An unexpected error occurred.  Error 10828.  Exception details: System.NullReferenceException: Object reference not set to an instance of an object.    
 at Microsoft.PerformancePoint.Scorecards.Server.PmServer.QueryTimeIntelligenceInternal(DataSource dataSource, DateTime currentTime, String formula)    
 at Microsoft.PerformancePoint.Scorecards.Server.PmServer.QueryTimeIntelligence(RepositoryLocation dataSourceLocation, DateTime currentTime, String formula)

An exception occurred while rendering a Web control. The following diagnostic information might help to determine the cause of this problem:  Microsoft.PerformancePoint.Scorecards.BpmException: Unable to get filter values.  PerformancePoint Services error code 20700.

This is odd to me, as I can trick the report to run by changing the date filters to another day, then back to the original days that error'ed out and everything is fine. Some guidance would be appreciated.
