 Class Types 

Purpose

The class type is a central concept in the classification system. The class type determines how classes are processed, and how objects can be classified and retrieved in these classes. In Customizing for Classification, you define the settings for a class type. You define class types for a specific object type, such as materials. You can then use classes of this class type to classify objects of this object type.

When you first create a class, you must enter a class type for the class. Each class type is a closed system. There is no link between the different class types.

Features

The class type determines the following:

  • Which object types you can assign to a class
  • Which class maintenance functions you can process
  • Whether you can classify objects in more than one class
  • Which class statuses, organizational areas, and text types are supported in class maintenance functions
  • Whether you can use engineering change management for classification
  • Which filter functions you can use to restrict the search result

 

Class types 001, 300, and 200 are defined for materials. In Customizing for Classification, you define the settings for a class type.

All materials can be classified with class type 001. Class type 300 is for variant configuration. Class type 200 is for classes that are used as class items in bills of material. You can classify the same materials separately in these class types.

You can use class type 012 to classify characteristics. This class type is defined only has the Keywords, Characteristics, and Texts screens in class maintenance functions. You can only classify characteristics in characteristics maintenance functions –you cannot use the assignment functions in the classification menu. In this case the indicator Classify master record only was set. No organizational areas were maintained for the characteristics. For this reason, if you create a class of class type 012, you cannot select any organizational areas.
