ImageThe Objective of Classifications :

•To define the properties of objects ( i.e Material , Equipment )
• Create Classes
• Assign Classes to Objects
The Purpose of Classifications in Plant Maintenance:
It allows you to use characteristics to describe all types of objects & group them into similar classify objects, in other words, so that you can find them more easily later.
The Features of Classification :

1. Defining the Properties of Objects

You use characteristics to describe the properties of objects. You create characteristics  centrally in the SAP R/3 System.

See the SAP Library, Characteristics (CA-CL-CHR).

2. Creating Classes

You need classes to classify objects. These classes must be set up. During set up you must assign characteristics to the classes.

3. Assigning Objects

Once you have created the classes you require for classification, you can assign objects to these classes. You use the    characteristics of the class to describe the objects you classify.This completes the data you require to use your classification system. You can then use your classification system to find objects that match the criteria you require.

ImageWhen you use classification to find objects, you use the characteristics as search criteria, and the system compares the values you enter with the values of the classified objects.

ImageThe class type is a central concept in the classification system. The class type determines howclasses are processed, and how objects can be classified and retrieved in these classes. InCustomizing for Classification, you define the settings for a class type. You define class types fora 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 aclosed system. There is no link between the different class types.

ImageIn This example, 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 type012, you cannot select any organizational areas.
