Add Exists filter into Reporting Services MDX

Question

Hi, I have a piece of auto generated MDX which I need to filter. This was a generated by Reporting Services when I added a parameter to a report reading from a cube.
WITH MEMBER [Measures].[ParameterCaption] AS [Dept].[DeptName].CURRENTMEMBER.MEMBER_CAPTION MEMBER [Measures].[ParameterValue] AS [Dept].[DeptName].CURRENTMEMBER.UNIQUENAME MEMBER [Measures].[ParameterLevel] AS [Dept].[DeptName].CURRENTMEMBER.LEVEL.ORDINAL
SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue], [Measures].[ParameterLevel]} ON COLUMNS , [Dept].[DeptName].ALLMEMBERS ON ROWS FROM 
( SELECT ( STRTOSET(@Yearly, CONSTRAINED) ) ON COLUMNS FROM [MyCube])
The parameter displays all [Dept].[DeptName] even though many are not in the report. How do I only show DeptName if it is in the report?

Hi Dark,
In SQL Server Reporting Services, the parameter will display all the Available Values for the user, and then the users select values from the drop-down list, and then filter the report data based on the selected values.
In your scenario, if you specify multiple available values from this parameter, then it will display all the DeptName on the report parameter pane. I have tested it on my local environment, the query works. Here is the sample query.
with member [Measures].[UniqueName]
AS
[Date].[Calendar].currentmember.uniquename
select [Measures].[UniqueName] on 0,
[Date].[Calendar].[Calendar Semester].members on 1
from(
select
( STRTOSET(@A, CONSTRAINED) )
ON COLUMNS FROM
