List summary with multidimensional data

[f-pasquier]

Hi All,

I need to apply custom summaries to a list. The list contains many fields like Brands and Regions, and also a measure called "DeliveredQuantity". I enabled a grouping for all Brands in this list and I must show the total of DeliveredQuantity at the end of each group. In this case the total is NOT the sum of the measure values. It must come from another consolidation in my data cube.

Brands1    Europe   2000
Brands1    Asia       1000
Total Brands1         7891
where 7891 is comes from the measure "DeliveredQuantity" but located in a special consolidated Region called  "World".

I tried to add an "Intersection" (or tuple)  [DeliveredQuantity, World] with the desired elements but nothing is shown in my summary row. How can I do this? Can someone help me?
