Use of 3 seperate "Result" Levels?

Question

Is it possible in BEx to use the values of 3 separate result subtotals
I
..A
....1)
....2)
....Total#
..B
....3)
....4)
....Total#
..Total abc
II
..D
....5)
....6)
....Total#
..Total abc
Total I-II
In this case Total#, Total abc, and Total I-II
I know that SumCT will give me Total# and SumRT will give me Total I-II but what about Total abc?

Answer 1

well it is a useful response to say "I searched XXX and YYY and it seems it is not possible"
But it is not useful
Q: how do I do XXX?
A: you cannot do XXX?
If everyone wrote such answers then these forums would be full of "I don't know" answers.
Better not post a response unless you have some value to add it keeps everything a bit less cluttered.
