Requirement Rule 
Use
You can use the Requirement Rule field in the sales order to control whether the confirmed delivery dates and quantities can be accepted or not. You can also specify that the system cancels the item if the ATP check cannot fully confirm it.
Prerequisites
In addition to CRM Enterprise, the following minimum system requirements apply:
● SAP SCM 5.0
● SAP ECC 6.0
● The system configuration for service parts management is active. You can find more information on this in the SAP Implementation Guide (IMG) under Customer Relationship Management ® Transactions ® Basic Settings ® Activate System Configuration for Service Parts Management.

Requirement rule D is not used in the following cases:
● The item is not yet due for the ATP check
● The item was partially delivered
For delivery groups or complete delivery the following applies:
● Requirement rule D must be activated end-to-end for all items assigned to the delivery group. Otherwise, the system issues an error message.
● If one of the items cannot be fully confirmed, the entire delivery group (that is, all the items assigned to the delivery group) is canceled.
The system can display a status to show the reason why the item was canceled. For more information, see the Implementation Guide (IMG) for Customer Relationship Management at Basic Functions ® Availability Check ® Availability Check Using SAP APO ® Define Cancellation Reason Codes for Unconfirmed Items.
Activities
You can maintain this field as follows:
● In the business partner master record for the sold-to party, under Sales Area Data on the ATP tab.
● In Customizing for Customer Relationship Management under Transactions ® Basic Settings ® Define Item Categories, in the Date/Qty are Fixed field. Only <blank> or X are possible. For more information, see the field help.
In the sales order, the field value can be proposed from
● The business partner master record
If this value is A or <blank>, it is copied to the sales order header, and the value for the item is taken from Customizing (see next point).
● Customizing
This value can be <blank> or X.
When you create the sales order, this field value is proposed in the sales order header on the Header Overview tab.
When you create a sales order item, the field value is copied from the header to the item, on the Schedule Lines tab.
You can overwrite this field value in the sales order header or item.
If there are any subitems, they inherit the field value from the higher-level item. You cannot change the field value in a subitem that results from an availability check (for example, in a kit component, or in a lower-level item resulting from the rules-based availability check).
