Demand Class Master Scheduling

You may wish to make further use of demand classes by segmenting not only your forecasted demand, but also your scheduled production by demand class:

In the above diagram, suppose your master scheduler has created three forecast names: FC-WHOLESL, FC-RETAIL, and FC-MAILORDER. You maintain and consume each forecast independently. However, rather than combining all forecast and sales order demand into a single master demand schedule, as was done in the previous diagram, your master scheduler maintains three demand schedules: WHLSAL-MDS, RETAIL-MDS, and MAIL-MDS. Each demand schedule consists of the forecast and actual demand associated to a specific demand class.

Your master scheduler also maintains three separate master production schedules: WHLSAL-MPS, RETAIL-MPS, and MAIL-MPS. You plan each master production schedule independently. In this manner, not only has the master scheduler broken out the sources of demand into separate groupings, but has also segregated units of production by demand class as well.

To drive the MRP plan, the master scheduler combines all sources of production into a single master production schedule, thus driving the MRP plan by the aggregate master production schedule. The master scheduler manually combines master schedules into a single master schedule, using the Load/Copy/Merge Master Demand Schedule or Load Master Production Schedule windows. See: Loading a Master Schedule From an Internal Source.

Maintaining the Master Production Schedule

You can allocate your discrete production by sales channel using demand classes. You can manually or automatically define discrete jobs to build configurations for your assemble-to-order or make-to-order products. You can also associate discrete jobs with sales orders for standard products to ensure customer satisfaction.

When you create a discrete job, it must consume the master production schedule for the demand class that satisfies the discrete job. Therefore, a discrete job can have an associated demand class. Oracle Work in Process automatically specifies the demand class when you manually define a job or create a configuration order for a specific sales order.
