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.

   To create and update demand classes:

1. Navigate to the Demand Class QuickCodes window.

2. Verify that the type of QuickCode you are creating is for a demand class.

3. Review the Access Level to determine whether you can add new QuickCodes or modify existing QuickCodes of this type:

User: No restrictions on adding or modifying codes are enforced.

Extensible: New codes may be added, but you can only modify or disable seeded codes if the application of your responsibility is the same as the application of this QuickCode.

System: Only code meanings and descriptions may be modified.

4. Enter a unique alphanumeric code that describes a demand class.

You can define a maximum of 250 QuickCodes for a single QuickCode type.

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.

5. Enter an abbreviated meaning of the demand class.

6. Enter an extended description of the demand class.

You can display the description along with the meaning to give more information about your QuickCode.

7. Enter an effective date (in the From field) on which the demand class becomes active.

Note: You cannot use the demand class before this date. If you do not enter an effective date, your demand class is valid immediately.

8. Enter a disable date (in the To field) on which this demand class expires.

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.

9. Check Enabled to indicate whether the demand class is enabled.

If you do not check this, you cannot insert additional records using your demand class, but can query records that already use this demand class.

10. Save your work.
