PI AF element totaling...

Good morning,

quick question that I am sure has an easy answer.  My apologies if this has been answered already, but I did not find anything in the search.

 

Here is my situation:

In PI AF, I have re-created our plant into 3 groups (base, CLD and facilities), each with motors, pumps, etc as children on multiple levels.  Lets assume I wanted to know the kW demand of the 'base' and 'CLD' groups for comparison.  In AF, all of the children have a kW demand tag.  How can I have the 'base' and 'expansion' elements list/show/calculate the total of all the children elements.

 

I have tried to do this using a PI AF formula, but this does not seem to be the most friendly approach.  Another way I have tried is with a PE calc, but that negates the point of the AF structure (and painful to create considering the amount of tags).  I would think there is a very simple way to do this.

 

A 'grand' total under WAP would be wanted as well - would assume same method would work.

 

Cheers and thanks in advance for any suggestions!
