Oracle Master scheduling is used for demand management, scheduling production, validating and 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.
You can estimate future demand for items using any combination of historical, statistical, and intuitive forecasting techniques. You can create multiple forecasts and group complimenting forecasts into forecast sets. Forecasts are consumed each time your customers place sales order demand for a forecasted product.
Material requirements planning (MRP) calculates net requirements from gross requirements by evaluating the master schedule, bills of material, scheduled receipts, on–hand inventory balances, lead times and order modifiers. It then plans replenishments by creating a set of recommendations to release or reschedule orders for material based on net material requirements.
Oracle Master Scheduling/MRP and Supply Chain Planning provide many different item and plan level attributes that give you the flexibility for generating material and distribution requirements plans that satisfy your business needs.
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.
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.
Discrete and Repetitive Scheduling
The master schedule can include discrete and repetitive items. Discretely planned items include flow schedules. A specific schedule date and quantity defines a master schedule entry for a discretely manufactured item. A schedule start date, a rate end date, and a daily quantity define a master schedule entry for a repetitively manufactured item.
Master Schedule Entries for Product Family Items
The master schedule shows sales order entries for product family items when you load sales orders for their member items. They also show demand schedule entries for product family items loaded from the forecasts.
