In PerformancePoint 2007 you have the capability to setup custom properties and pass them into dashboard objects. This is especially useful for simplifying dashboards where you are linking scorecard KPIs to report views. Alyson Powell Erwin outlines how to do this in the PerformancePoint MSDN blog:

 

 

This is very handy. By setting up a custom property that contains measure names for the KPI you can use one report for each data source and pass the value of the custom property into the [Measures] endpoint on the report view. If you have a scorecard with 20 KPIs from the same data source and each KPI displays two report views it trims the number of reports required from 40 to 2.

 

Issue Found - Solved in SP1

 

However, I noticed something going awry when doing my performance testing while running Profiler against the Analysis Services database. Each time I clicked on a KPI it would execute the query for the two report views as expected AND submit a query for the scorecard with NO FILTERS. This basically amounts to running the scorecard query for all time because we pass the org and date filters in from the dashboard filter selections. This obviously has a negative effect on overall query performance from the Analysis Services server. However, in testing PerformancePoint 2007 SP1 I found that this problem has been addressed although I saw no mention of it specifically in the SP1 release notes. It is easy for this issue to go unnoticed because of the good caching done by Analysis Services - provided there is sufficient CPU and memory on the Analysis Services server.
