When the Microsoft PerformancePoint Scorecard group released Update Rollup 3, you will have the ability to have dynamic row members using an MDX Expression. You can also use a Page Filter and allow the end user to slice the Row Members and filter them out. Using the following MDX Expression, you can do same!
<$[Personnel].[Hierarcy]$> is the value you need to notice, that format has a matching Page Filter. So when the end-user slices the Page Filter, the Personnel members will be shown where the Measure is not Null. That will show only row members where they have values.
