Defining Classes as BOM Items

Purpose

You can use class items to control the selection of variant parts in a BOM. Variant parts are classified in a class, and the class is entered in the BOM as a class item. When you configure the material, the class is replaced by a suitable variant part.

Class items can help you to simplify maintenance of BOMs for configurable materials:

• You only enter one item for the class, instead of several items for the individual variant parts.
• You do not need to create and assign selection conditions.
• You can classify additional objects in the class at any time, without having to change the BOM.

When you configure the material, the class item is replaced by a specific component.

Prerequisites

You can only uses classes for classifying the following objects as BOM items:

• Materials
• Documents

The class type determines whether a class can be used as a class item in BOMs. In Customizing for the Classification System, the Class node indicator must be set for the class type. In the standard system, class types 200 and 300 are defined for materials, and class type 201 is defined for documents.

Configurable materials can be assigned to classes of class type 300. If a class item is replaced by a configurable material, this material is added to the configuration structure automatically.

Process Flow

1. Create characteristics that describe the objects.
2. Create your class using a class type for class items.

Maintain the additional data for the class (see the SAP Library CA - Cross-Application Components ® Classification (CA-CL) ® Classification (CA-CL) ®Additional Data).

3. Assign objects to the class and assign values to the characteristics of the class for each object.
4. Enter the class as a class item in the BOM of the configurable material – see the SAP Library Bills of Material (PP-BD-BOM).
