I have this scenario :
- If there's OH inventory on item A, use item A in the formula
- If there's no OH inventory on items A. use a phantom item B which can be produced from item c and a route
I set both item A and item B to the same plan group, set priority 1 on item B and qty 1, set priority 2 on item A and no quantity
The problem is with the setting above, planning optimization still use item B although there's no inventory on item B and there's OH inventory on item A
