Count of Weeks where a certain measure is 0

Question

Hi,
I'm trying to create a calculated measure which would give me count of weeks where a certain measure say Sales is greater than 0. I have a hierarchy YEAR->QUARTER->MONTH->WEEK in time dimension DIMTIME. And I have used the expression COUNT(MYCUBE_ONHANDASSETS GT 0) to get the count. But this expression gets count of weeks from all the years instead of selected time periods. Lets say I have the measure MYCUBE_SALES greater than 0 at 2 weeks in Jan 2010, then the count should be 2 at level Jan 2010 in the hierarchy. But it shows 50 which is total weeks in year 2010 where MYCUBE_SALES is greater than 0.
Can anyone help me solving the issue ?
Thanks,
RK

You should be able to copy the data from your MYDWCUBE_AVG cube to COUNT_CUBE using OLAP DML.
First limit the dimensions to the appropriate leaf values, then assign. The ACROSS clause should list the partition template (if MYDWCUBE_AVG is partitioned) or the composite if it is not. I am approximating below.
LIMIT TIME TO TIME_LEVELREL 'MONTH'
LIMIT PRODUCT TO PRODUCT_LEVELREL 'SKU'
...other leaf level conditions
LIMIT COUNT_CUBE_MEASURE_DIM TO 'ONHANDASSETSCOUNT'
LIMIT MYDWCUBE_AVG_MEASURE_DIM TO 'ONHANDASSETS'
COUNT_CUBE_STORED = MYDWCUBE_AVG_STORED ACROSS MYDWCUBE_AVG_PRT_TEMPLATEIf you are in 11.2.0.2 then you can also use DBMS_CUBE to copy the data without needing to worry about the physical object details.
begin DBMS_CUBE.BUILD(q'! COUNT_CUBE USING
     FOR
        "TIME" LEVELS ("TIME"."MONTH"),
        "PRODUCT" LEVELS ("PRODUCT"."SKU"),
         ... other leaf level conditions ...
     BUILD
       SET COUNT_CUBE.OnHandAssetsCount = MYDWCUBE_AVG.OnHandAssets
end;
