Aggregate only portion of sparse dimension

Question

System 9 BI+(9.3) - Here's my problem.
I need to aggregate only a portion of a sparse dimension.
All members are stored data. Dimension looks like this:
Total Europe
-Western Europe
--France
--Germany
--United Kingdom
--Iberia
---Spain
---Portugal
-Central Europe
-Eastern Europe
I tried
FIX(May, 2009, @IDESCENDANT("Iberia"))
agg(Products,Channel)
ENDFIX
but all it does is aggregate Spain and Portugal, but not Iberia.
I also tried
FIX(May, 2009, @IDESCENDANT("Western Europe"))
agg(Products,Channel)
ENDFIX
but again all it does is aggregate France, Germany, Spain, Portugal, bit not Iberia or Western Europe.
Any ideas/assiatnce appreciated.

Answer 1

The comment on Network54 (sorry, I forgot who posted it) is on the money -- you are not aggregating Region/Geography/whatever your dimension is called.
Assuming your dimension order is:
Region
Products
Channel
I would write a script like:
FIX(@LEVMBRS("Products", 0), @LEVMBRS("Channel", 0))
@IDESCENDANTS("Iberia") ;
ENDFIX
FIX(@IDESCENDANTS("Iberia"))
AGG("Products", "Channel") ;
ENDFIX
You will have to rearrange this a little bit if your dimension order is different. As an example, if your dimension order is Products, Region, Channel, your code might look like:
FIX(@RELATIVE("Iberia", 0), @LEVMBRS("Channel"))
AGG("Products") ;
ENDFIX
FIX(@IDESCENDANTS("Products"), @LEVMBRS("Channel"))
@IDESCENDANTS("Iberia") ;
ENDFIX
FIX(@IDESCENDANTS("Products"), @IDESCENANTS("Iberia"))
AGG("Channel") ;
ENDFIX
This may look painful, but you may find a significant performance increase.
Take a look at my blog post, ignore all the Planning stuff, and jump to the bit where I explain how a BSO db consolidates. The concept is identicial to the one I outline above.
