Master scheduling is used for:
- demand management
- scheduling production
- validating the production schedule
- managing the production schedule
You use the schedules generated by master scheduling as input to other manufacturing functions, such as material requirements planning and rough–cut capacity planning.
Master Demand Schedule (MDS)
The MDS is a statement of demand and contains details of the anticipated shipment schedule. You can consolidate all sources of demand into a master demand schedule to represent a statement of total anticipated shipments. The master demand schedule provides an extra level of control that allows you to view and modify your statement of demand before creating a detailed production schedule.
You can use the time–phased master demand schedule as input to the master production scheduling process or the material requirements planning process. Some of the demand types that the MDS considers are:
• item forecasts
• spares demand
• sales orders
• internal requisitions
Supply Chain Planning users can also manage interorganizational demand and create distribution requirements plans (DRP) from an MDS.
Master Production Schedule (MPS)
The MPS is a statement of supply required to meet the demand for the items contained in the MDS. The master production schedule defines the anticipated build schedule for critical items. An effective master production schedule provides the basis for order promising and links the aggregate production plan to manufacturing by specific items, dates, and quantities. You can use the MPS to level or smooth production so that you effectively utilize capacity to drive the material requirements plan.
