Final answer:
The MRP system will likely generate a single order of 120 units for the 'Styrene Back Assembly' since the requirement exceeds the minimum lot size policy of 100 units. However, the configuration of the MRP could result in an order of 200 units if it adheres strictly to lot sizes, which needs to be confirmed.
Step-by-step explanation:
The question pertains to a scenario involving the Material Requirements Planning (MRP) system. When dealing with lot sizing policies in MRP, the system generates orders based on the set rules. In this case, the minimum lot size quantity is specified as 100 units. As the requirement is for 120 units of the 'Styrene Back Assembly', the system will probably create a single order of 120 units because the order quantity exceeds the minimum lot size.
However, MRP systems can be configured in different ways, depending on the specific parameters set within the system. If the system strictly adheres to the lot sizes and does not allow scaling, it might generate an order of 200 units, covering the requirement and aligning with the lot size multiples. It's important to note that the specific configuration of the MRP system will greatly influence the outcome in real scenarios.
