When you create a forecast and/or a master schedule, you have the option of associating a demand class with it. When you book a sales order that has an associated demand class, the forecast consumption process searches the forecasts for entries that have the corresponding demand class. The consumption process attempts to consume these entries first.
The shipment of a sales order or the creation of discrete jobs within a particular demand class causes relief to occur in any master demand schedule and master production schedule that is associated with that demand class.
Note: You cannot change the values in this field after committing them. To remove an obsolete QuickCode you can either disable the code, enter an end date, or change the meaning and description to match a replacement code.
Note: You cannot use the demand class before this date. If you do not enter an effective date, your demand class is valid immediately.
Note: You cannot use the demand class after this date. Once a demand class expires, you cannot insert additional records using the demand class, but can query records that already use the demand class. If you do not enter a disable date, your demand class is valid indefinitely.
