Product A (make to stock) has 2 BoMs : BoM1 and Bom2. BoM1 is used most of the time, but we sometimes want to use BoM2.

We can receive multiple sales orders for this product each day.
In order to have just one production order, we have setup a minimum stock rule (min : 0, max : 0, multiple : 1)

The scheduler generates one production order, but this production order is confirmed by the scheduler.
In this state, we cannot change the BoM from BoM1 to BoM2.

Did we miss something? Is there another way around?

Thanks
