Measure of measure

Hi,

actually the model is working even with filter on DIM table. The behaviour I'm not still able to obtain is the following.

I'm able to have the rotation index over a single family but, if I select all the family or even just two it doesn't give me back the index.
In my model I have the "Plant" in which I have many families: what I need to have is a total consumpion (and as a consequence the rotation index) even for the sum of all the families.

Here the example of what I've: with one family it works

With two or more it stops to return me the desired value of total consumption and IR as a consequence

please help me to solve this
