Requirement Rule

You 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 availability 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 Customizing under Start of the navigation path Customer Relationship Management Next navigation step Transactions Basic Settings Activate System Configuration for Service Parts Management End of the navigation path .

Features

The following values are available for the Requirement Rule field:

Date and Quantity are Fixed (BOP Top Priority)	Date and quantity cannot be changed by the system, if quantities come to backorder processing, they have priority there	No	Yes

Requirement rule Reject Item (If Not Completely Confirmed) is not applied in the following cases:

The item is not yet due for the availability check
The item was partially delivered

For delivery groups or complete delivery the following applies:

Requirement rule Reject Item (If Not Completely Confirmed) 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.

Activities

You can maintain this field as follows:

On the account overview page for the sold-to party in the Sales Area Data area under Available-To-Promise (Availability Check).
In Customizing under Customer Relationship Management Transactions Basic Settings Define Item Categories , in the Date/Qty Are Fixed field. The only options here are <empty> or Date and Quantity Are Fixed (BOP Top Priority). 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 Proposal from Item Category or <blank>, it is copied to the sales order header, and the value for the item is taken from Customizing (see next point).
From Customizing
This value can be <empty> or Date and Quantity Are Fixed (BOP Top Priority).

When you create the sales order, this field value is proposed in the sales order under Details.

When you create a sales order item, the field value is copied from the header to the item.

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 subitem resulting from the rules-based availability check).
