Case statement with dimension in MDX Query

Question

In a MDX query I am using with case statement in SSRS Report. It is not returning the desired result. It should filter [Facility Market] based on the selection of the Territory parameter.

with member [Dim Facility].[Facility Market].[Facility Market] as
case  [Dim North Texas Sales].[North Texas Rural Sales Territory].currentmember

when   [Dim North Texas Sales].[North Texas Rural Sales Territory].&[NTXSalesRuralEast] then [Dim Facility].[Facility Market].&[OKLAHOMA] 

end

select......

I would like to change the value of facility market dimension based on the parameter selection and filter the dataset based on that

Answer 1

Case statements only work with scalar values.

You should rather use an expression like this one:

IIf([Dim North Texas Sales].[North Texas Rural Sales Territory].CurrentMember IS [Dim North Texas Sales].[North Texas Rural Sales Territory].&[NTXSalesRuralEast],
[Dim Facility].[Facility Market].&[OKLAHOMA],
...)

Answer 2

with member [Dim Facility].[Facility Market].[Facility Market] as
case  

when  [Dim North Texas Sales].[North Texas Rural Sales Territory].currentmember IS [Dim North Texas Sales].[North Texas Rural Sales Territory].&[NTXSalesRuralEast] then [Dim Facility].[Facility Market].&[OKLAHOMA] 

end

select......
