By default, the Components List from original Product Structure will be used automatically for each new Production Order. While Production Order has a "Created" or "Released" Status, any new Components can be optionally added into Components List of Production Order. The required Part Number, Modification and Version for the new Component can be entered manually or selected from list. The mandatory Quantity per Unit for the new Component can be also entered manually. The corresponding Quantity On Order will be calculated automatically (and vice versa). If Routing is assigned for the Production Order, then the Operation from this Routing can be optionally specified for new Component.
