Calculation shows for all members... why?

[hwkranger]

So....

I have a problem -- it's the same problem I have with KPI's. I created KPI's, but when I put them in SSRS to report them ALL members are associated with the KPI and it seems impossible to filter which members I want from a consumed parameter.

So I changed it to a calculation -- this is one of my trends.

Case
 When IsEmpty
  (ParallelPeriod
   ([Dim Time].[Hours After Midnight].[Hours After Midnight],1,
       [Dim Time].[Hours After Midnight].CurrentMember))
  Then 0  
 When  (
   [Measures].[Average Service Window Time] - 
   ([Measures].[Average Service Window Time], 
    ParallelPeriod
     ([Dim Time].[Hours After Midnight].[Hours After Midnight],1,
       [Dim Time].[Hours After Midnight].CurrentMember))
      /
      ([Measures].[Average Service Window Time],
       ParallelPeriod
        ([Dim Time].[Hours After Midnight].[Hours After Midnight],1,
         [Dim Time].[Hours After Midnight].CurrentMember)))
       >=.01
  Then 1
   When(
    [Measures].[Average Service Window Time] - 
     ([Measures].[Average Service Window Time],
      ParallelPeriod
       ([Dim Time].[Hours After Midnight].[Hours After Midnight],1,
        [Dim Time].[Hours After Midnight].CurrentMember))
       /
        ([Measures].[Average Service Window Time],
         ParallelPeriod
          ([Dim Time].[Hours After Midnight].[Hours After Midnight],1,
            [Dim Time].[Hours After Midnight].CurrentMember)))
        <=.01
  Then -1
   Else 0
End

When i do this, it flushese out all the members of a measure to all dimensions.. I'm perplexed...

thanks!
