Big Choi,
Sorry, it did not help. I think you probably meant that I should keep the column with COS=0.
No matter what combination I try, the result is the same.
On a side note, I see that the problem arises out of two reasons:
1. We have recursive BOM's. e.g. Material A has material B, C, D as components. Material B uses Material A, C, D as components. The BOM's are marked recursive.
2. We also have coproducts.
May be you or Ajay, Udo, Arturo, Maria-Munoz can shed some light on this issue?
Cheers,
TD
