MPS Flag
This field applies to APS and MRP.
On the Items or Multi-Site Items form, select the box to indicate that this is a master production schedule (MPS) item or accept the default of cleared. If the item is a master production scheduled item, you are responsible for maintaining the master production schedule information prior to the MPS Plan (planning fence) date displayed on the Master Production Schedule form.
See Using a Master Production Schedule
Use MPS items to control production of key items to help you protect your schedule from fluctuations in order-based demand (forecasts, customer orders, parent job orders, etc.). A master production schedule is a manually created, anticipated build schedule for these MPS items.
On the Master Planning Display, Planning Detail Display, and Planning Summary Display forms, this field indicates that this is a master production schedule (MPS) item.
Running MRP or APS Planning does not generate planned jobs or purchase orders for MPS items, or give you an exception message about rescheduling a job or purchase order (however, MRP and APS both plan components of MPS items).
