Logic for Inverse BOM

[kesavadas_thekkillath]

I have builded the itab like this.

LEVEL CHILD PARENT QTY

1 C1 P1 2

1 C1 P2 3

2 P1 P3 2

2 P1 P4 2

2 P1 P5 2

3 P2 P6 2

When i give C1 as Input( The top most Node )

The output must be calculated for its lowest nodes

C1 -> P1 -> P3 = 4

C1 -> P1 -> P4 = 4

C1 -> P1 -> P5 = 4

C1 -> P2 -> p6 = 6

Displayed as

P3 - > 4

P4 - > 4

P5 - > 4

P6 - > 6

I just need a logic for this....Its a traversal technique..

Plz suggest me a logic
