Scrap!! How to maintain in Sub Contracting??

Hi All,,

How to manage the Waste% vendor wise in the Sun Contracting???

We have given a solution for the Waste% to be caluclated either by the maintaining a Material code (Scrap) in the BOM of the Finished Material or by giving a Component Scrap in the BOM???

but they are not in a Position to maintain it in the BOM or Material Code.

Cleint want to maintain Vendor

Can anyone have any alternate solution????

Thanx Regards,

Kumar Rayudu
