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