MDX How to use CASE to check a level value - case

Question

I'm new to BI and MDX and have a need to do this. I have a dimension that looks like this:
<Dimension name="JobDim">
<Hierarchy name="Job" hasAll="true" primaryKey="jobID">
<Table name="JobDim" schema="dw"/>
<Level name="Job Code" column="jobCode" type="String" uniqueMembers="false"/>
</Hierarchy>
<Hierarchy name="Job Status" hasAll="true" primaryKey="jobID">
<Table name="JobDim" schema="dw"/>
<Level name="Job Status" column="status" type="String" hideMemberIf="IfBlankName"/>
</Hierarchy>
</Dimension>
I have a calculated measure and I need to set the value of this measure depending on the 'job status', so if the job is 'complete', set the measure to 100, otherwise set its value to 200 (the value to be used is more complex but for this example purpose, this is good enough). I'm using something like this:
<CalculatedMember name="Earned Revenue" dimension="Measures" formatString="$#,###.00;($#,###.00)" aggregator="sum">
<Formula>case [JobDim.Job Status].CurrentMember
when [JobDim.Job Status].[Complete] then 100
else 200
end
</Formula>
</CalculatedMember>
I've tried different variations of the code above, but none seem to work (some even cause a crash when I try to run the report). Anyone has done something like this in the past that can provide me an answer?

Answer 1

You need to evaluate that tuple against some measure. Remember that in MDX evaluations are done against the level/aggregate results, not on a row by row basis.
From your description it looks like Job Status should be a property of the level Job Code, and not a level.
Try the following on your schema:
<Dimension name="JobDim">
<Hierarchy name="Job" hasAll="true" primaryKey="jobID">
<Table name="JobDim" schema="dw"/>
<Level name="Job Code" column="jobCode" type="String" uniqueMembers="false">
<Property name="Job Status" column="status" type="String"/>
</Level>
</Hierarchy>
</Dimension>
and on your calculated measure
<CalculatedMember name="Earned Revenue" dimension="Measures" formatString="$#,###.00;($#,###.00)" aggregator="sum">
<Formula>case [JobDim.Job Status].CurrentMember.Properties("Job Status")
when "Complete" then 100
else 200
end
</Formula>
</CalculatedMember>

Better to use IIF than CASE if possible as it is generally quicker. Assuming [JobDim.Job Status].[Complete] is a member in your cube then the IS operator should be ok to use:
IIF(
[JobDim.Job Status].CurrentMember
IS [JobDim.Job Status].[Complete]
,100
,200
)
