MDX for OLAP Universe.

Question

Hello!
I have a scenario wherein I have to create a custom dimension restricting some values to be displayed. The dimension I am trying to restrict here is Quarter - [ZCALQRT].[LEVEL01], which has values like Q3 2011, Q4 2011, Q1 2012,Q2 2012 on a rolling quarter basis. My requirement is to restrict the last quarter to be displayed.  I have tried the following menthods to achieve this:
1) Create a new dimension object with the following syntax:
<EXPRESSION>
WITH MEMBER [Measures].[Delta] ASu2019
[Measures].[4J68GNRER52B7BV68B1GHWUA8]-[Measures].[4J68GNC1P7UW62S9WMWRXSWUO]u2019
SELECT
{[Measures].[4J68GNC1P7UW62S9WMWRXSWUO],[Measures].[4J68GNRER52B7BV68B1GHWUA8], [Measures].[Delta]} ON COLUMNS,
NON EMPTY {[ZCALQRT].[LEVEL01].members} ON ROWS
FROM [$Y_ZAPOH]
WHERE (EXCEPT([ZCALQRT].[LEVEL01].[[2ZCALQRT]].[Value],[ZCALQRT].[LEVEL01].[[2ZCALQRT]].[Value].CurrentMember.LastSibling))
</EXPRESSION>
So, here I tried to restrict the dimension in the where clause using the EXCEPT(,) function. But on using this new custom dimension in Web I the error message I receive is "Some objects are not available in the Universe".
2) Create a restriction for the object in the where clause:
<EXPRESSION> (EXCEPT([ZCALQRT].[LEVEL01].[[2ZCALQRT]].[Value],[ZCALQRT].[LEVEL01].[[2ZCALQRT]].[Value].CurrentMember.LastSibling))</EXPRESSION>
This gives and error message with MDX syntax being invalid.
Can anyone please suggest a work around for restricting the dimension in the SELECT/ WHERE clause or a PRE-DEFINED FILTER.
Any inputs are highly appreciated.
Thanks,
Vivek.

Hi Ingo,
Thank you for the information. I will try doing that in the SAP BEx query end. However, I found some examples with the MDX which can filter the members based on their levels. One specific example of referring to a member is as follows:
If I need to exclude the last value in a rolling value set, I tried to use the EXCEPT(,) function and referring the member in a predefined filter:
<EXPRESSION>EXCEPT([0CALQTR].[LEVEL01],[0CALQTR],[LEVEL01].CurrentMember.LastSibling)</EXPRESSION>
Can you please suggest if anything is wrong with this MDX statement?
Any inputs are highly appreciated.
Thanks,
Vivek.
