Thanks Imke, I was trying to reference that blog post for what I am trying to do but wasn't able to. Basically I would like a slicer that changes the Axis Fields (Categories) section of the PowerPivot Field List.
So I might have Region in the Axis Fields (Categories) section and my PivotTable or Chart will have data displayed by region. I would Like to have a slicer that lets you choose Region, Sales Rep, or Country, etc. and then the PivotTable or Chart will update to reflect the selection.
Thoughts?
