We have a material that we produce as a by-product but we also have PIR, sales order and planned order for it.
In this scenario, we also have several sales orders for the same material that reduces the quantities Ind. requirements. When this happends, the system creates a planned order indicating that we need to produce this by-product ASAP. So far, so good.
The problem begins when we already have a reservation of this by-product (derived from a production order of the main product) with a date in the future (after the sales order dates). In this case the system keep the reservation as a stock inbound, but after I run MRP it won´t reduce the planned order.
I already tested creating an MTS production order for that by-product. The system reduces the planned order and give me an exception message indication that the date should be change.
That´s exactly the behavior that wan´t for the by-product based on the reservation.
Any one knows if this is possible as a customizing ou some kind of development?
Thanks in advance.
