When using PerformancePoint Designer in SharePoint 2010 and trying to add a new item say a SQL Server connection you might get the error 'An Unexpected Error Occured. An error has been logged for the Administrator'

If you check the Event log on your client machine you should find a more detailed but equally cryptic error.

An unexpected error occurred. Error 15568.

Exception details:

Microsoft.SharePoint.SPEndpointAddressNotFoundException: There are no addresses available for this application.

at Microsoft.SharePoint.SPRoundRobinServiceLoadBalancer.BeginOperation()

at Microsoft.PerformancePoint.Scorecards.BIMonitoringServiceApplicationProxy.GetBalancerContext()

at Microsoft.PerformancePoint.Scorecards.BIMonitoringServiceApplicationProxy.ExecuteOnChannel(CodeBlock codeBlock)

First check in Central Administration check you have a PerformancePoint Services application created.

My problem was that although the services application was created the service instance itself was not running. Goto Central Admin - System Settings - Manage Services on Server and make sure the PerformancePoint service is started or start it youself.

Why you are not given the option in the Services App to do this automatically is a mystery to me.
