By-Product

[samudaya]

Hi All,

When I use webERP I found some problem regarding how to configure by-product available process.

Usual manufacturing (No Problem)
Resource A (x quantity) + Resource B (y quantity) => Product C (n quantity)


Manufacturing with by-product (How to handle this ?)
Resource A (x quantity) + Resource B (y quantity) => Product C (n quantity) + By-Product D (m quantity)

Does anybody know how to make these kind of BoMs?

Thank you very much....

Best Regards
Samudaya
