Hi,
Header Material : Segment 1 : Base Qty as 1 nos.
Item 0010 : Ring : Qty 1 nos
Item 0020 : Segment 2 : Qty as -1 or 1- nos.
Item 0030 : Segment 3 : Qty as -1 or 1- nos.
By do so, you are consuming ring and converting it to different segments. Like Dis-assmbling.
If suits mark as CORRECT and close the post. If not get back.
Thanks With Regards,
