How to Identify Nodes in Hierarchy in CR Enterprise

Hi,

I am using Crystal Reports Enterprise 4.0 and connected to BEx query via BICS connection. My requirement is to show hierarchy as below:

                           Cost

AAA                       

     BBBBB                 1  

     BBBBB                 1

     BBBBB                 1

     BBBBB                 1

AAA Total -                 4

BBB

     CCCCC                  2

     CCCCC                  2

BBB Total -                  4

all we can get is this-

AAA               4

     BBBBB          1

     BBBBB          1

     BBBBB          1

I need to make the parent node  and add Sub totals bold. Not sure how to identify parent nodes in Enterprise, as I know in CR2011 we get hierarchy node ID. Beside we would like to keep keyfigure columns allied as first example. 

Thanks,
