This Article will cover How Sap Classification is handled.

It starts with SAP Characteristics and Classes Customizing to get an overview of Classification.
The second part is more technical and covers the Master Data for Classification (ex: AUSP ).The last part explains how to handle Characteristics in ABAP Coding: How to read and Update Characteristics.

SAP Characteristics Customizing

Let’s start by the SAP Characteristics Customizing.
The main Tcode for Characteristics Customizing in SAP is CT04 and CL02 for Class Customizing.

SAP Classification Tables

Main SAP Classification Tables & Fields

The most importing SAP classification Tables are

  • AUSP: this table saves the value of characteristic for a single business object ( Customer, material … ).
    • The AUSP-OBJEK refers to business object key
      • for example Customer ID in table KNA1-KUNNR
      • or Material Number from MARA-MATNR).
    • The value of the Characteristic can be found in AUSP-ATWRT ( neutral value).
  • CABN: This Table contains the property of the Characteristic. It pilots the type, description … of the characteristic.
  • KLAH: The Class of Characteristic are kind of grouping/set of Characteristics.

When working in ABAP Code with Characteristic, the most important fields to help out extract classification values:

Table Description
AUSP-OBJEKkey of object for Characteristic ( Material and Customer and … )
AUSP-ATWRTValue of Characteristic
CABNT-ATBEZDescription of Characteristic

List of related SAP Classification Tables

Useless to try an SQVI for Classification. Actually the AUSP-OBJEK has hardly the same kind and length as the MARA-MATNR or KNA1-KUNNR.
A new view between AUSP and KNA1 or MARA can solved the problem.

To make your life easier, here the join to do in order to retrieve Characteristic data in any ABAP Code.

Join between CABN, AUST and KNA1 can be :

  • AUSP-ATINN = CABN-ATINN
  • CABNT-ATINN = CABN-ATINN
  • KNA1-KUNNR = AUSP-OBJEK
