"Semi/Non additive measure with" : "LastChild Across All Dimension" OR "LastChild Across Time and MAX across All Other Dimension"

Question

Hey All
I am using the SQL SERVER 2008R2 standard edition so please be mindful when posting any suggestion if that will work on this edition or not.
Here is the situation: I have Cube with one fact table "Positions". Measure I am querying is "AUM" and Dimensions across user can query are combinations of {"Portfolio", "Security" and "Time"}.
I am receiving the "AUM" values at "portfolio+Security+Time" level. AUM is actually the Portfolio level value. so sample data I receive would like this.
PORTFOLIO SECURITY TME AUM
A SEC1 JAN-1 100
A SEC2 JAN-1 100
B SEC1 JAN-1 200
B SEC3 JAN-1 200
A SEC1 JAN-2 300
A SEC2 JAN-2 300
B SEC1 JAN-2 400
B SEC3 JAN-2 400
So, as shown in above example , we received same "AUM" value for a given portfolio and time. (regardless of what security value is).  
And as AUM is the snapshot values, we can not sum across time as well, so if user is looking across time we need to pick Last values.
Now when user wants to view this data from cube, two different ways s/he wants to look at it.
option one: AUM at port+sec+time level. that is same as shown above in example.
option two: AUM at portfolio level only,  (notice that this is across time so results are picking values for time=JAN-2)
PORTFOLIO AUM
A 300
B 400
GRAND TOTAL 700
I have applied the "LastChild" aggregation property to measure to achieve "Do no Sum across Time "behavior. but with this I also get "SUM Across Except time" and hence my AUM values get summed across Portfolio and security as
well. I have also enable Time Intelligence to enable MTD, YTD calculations.
I tried to add SCOPE statement for Security before and after the "time calculations" yet I am not able to achieve expected behavior.
here is the calculated member definition, and scope statement i have tried.
CREATE MEMBER
CURRENTCUBE.[MEASURES].[AUMNetBaseCurrency] AS
[Measures].[AUMNetBaseCurrency_Raw_Max],
FORMAT_STRING = "#,##0.00 ;( #,##0.00 )",
VISIBLE = 1 , DISPLAY_FOLDER = 'Position';
After this I have MTD and YTD time calculation for few measures including AUM.
I tried placing the following SCOPE for AUM before and after the Time calculations but it no difference in result, in fact it seems like it has no affect of scope at all due to the "LastChild" aggregate property applied on measure.
SCOPE([MEASURES].[AUMNetBaseCurrency]);
SCOPE([Security].[Symbol].[All]);
THIS = MAX([Measures].[AUMNetBaseCurrency_Raw_Max]);
END SCOPE;
END SCOPE;
so options I am thinking of but do not have clear idea how to implement those are:
0) why my Security Scope Statement are not showing any effect, and can we do something about it?
1) Can be change "SUM" behavior to "MAX" / "MIN" across all Dimension except time.
2) Is there a way to implement "LastChild" across all dimension instead only across Time.
3) Should I need to make any changes at Fact table level to achieve this ? I refer one Q&A in this forum that suggested to create such measure in different measure group but it doesn't have any clarification.
Any help would be appreciated.
Thanks

hi,
you will have to enable cache in your nqsconfig.ini file under the section
# Query Result Cache Section
[ CACHE ]
ENABLE     = YES;
cache seeding is also a mechanism through which the data would be updated in the cache.
