We have work item hierarchy A-->B-->C. Where A is parent of B and B is parent of C.
Lets say A has two child B1,B2 and B1, B2 also have two each C1,C2 and C3,C3 respectively.
I have created the  report in Jazz report Engine which all this hierarchy of the task with and time spent.

I want to add two more column for A and B which the percentage of of has been completed calculated on the basis of  immediate children.

B1 mark as complete it means 20% of A has been completed that should be shown in column. If C1,C2 have been completed i.e B1 has has been completed 100% since it has only two child tasks.

I am wondering if it is feasible in JSR. Thanks in Advance
