Microsoft has for some reason decided that PerformancePoint should use the SQL Server 2008 OLAP drivers to connect to the cube so if you have an environment that is running SharePoint 2013 and SQL Server 2012, what will happen is PerformancePoint will not be able to access the cubes. the following is copied from another blog with the solution
ERROR : The data source provider for data sources of type 'ADOMD.NET' is not registered. Please contact an administrator. PerformancePoint Services error code 10115

On SQL Server you need to install SQL Server 2008 R2 ADOMD.NET
you can download from http://www.microsoft.com/en-us/download/details.aspx?id=16978
And After that you need to Restart IIS .
