Understanding Demand Rules

Demand rules affect how the system processes demand data and cumulative quantities, and how requirements are updated during the shipping process. For example, demand rules enable you to:

• Specify the day on which a customer's week begins, allowing you to determine whether a demand record is associated with the current week or the prior week.

• Adjust shipment dates for nonworking days.

• Increase or decrease cumulative quantities when updating the cumulative quantity shipped.

• Replace the existing demand with the new demand that is associated with a particular Ship To record.

• Calculate ahead or behind values to adjust the demand before you create the sales order.

• Establish shipment and delivery times based on the branch/plant, Ship To, or Sold To time zones.

You set up demand rules at the customer or ship to level for each customer.

The system uses these tables when processing demand rules:

• F40R11

• F40R12

• F40R41

• F40R42

• F40R12WF

• F40R20

• F40R23

• F40R24
