ALV Report

Hi all,

     I am developing a alv report which has 3 steps i.e for example, I have a PO no. DX001 which has 3 items in it say, AM01,AS01 and AU01.

All these 3 items further has their BOM items.

The report looks lik,

PO No. : DX001

Item No. : AM01

Bom Items : A

                   B

                   C

Item No.:AS01

BOM Items: D

                   S

                   E

Item No.:AU01

BOM Items : F

                   P

                   H

How do I achieve this. Can anyone gimme some idea pls..

Thanks in advance.
