• What is the cause and solution for SAP error message QG711 - The classes must be defined in descending order ?

  The SAP error message QG711, which states "The classes must be defined in descending order," typically occurs in the context of quality management (QM) when you are trying to define or maintain classification systems for inspection characteristics or quality-related data.
  Cause:
  This error arises when the classification system you are trying to set up does not follow the required hierarchical structure. In SAP, classes (or characteristics) must be defined in a specific order, usually from the most general to the most specific. If the classes are not arranged in descending order, the system will throw this error.
  Solution:
  To resolve the QG711 error, you should:
  
  
  Check Class Hierarchy: Review the classes you have defined. Ensure that they are organized in a descending order based on their hierarchy. For example, if you have classes A, B, and C, and C is a subclass of B, which in turn is a subclass of A, the order should be A > B > C.
  
  
  Rearrange Classes: If you find that the classes are not in the correct order, you will need to rearrange them. This can typically be done in the classification view of the relevant transaction (e.g., CL02 for class maintenance).
  
  
  Validate Class Definitions: After rearranging, validate the class definitions to ensure that they meet the requirements of the system.
  
  
  Check Dependencies: If there are dependencies or relationships between classes, ensure that these are correctly defined and do not violate the descending order requirement.
  
  
  Consult Documentation: If you are unsure about the correct hierarchy or how to define classes, refer to SAP documentation or consult with a colleague who has experience in SAP QM.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CL02 (Change Class) or CL03 (Display Class) to manage class definitions.
  SAP Notes: Check for any relevant SAP Notes that might provide additional insights or updates related to this error.
  Quality Management Configuration: Familiarize yourself with the configuration settings in the Quality Management module, as understanding the overall structure can help prevent similar issues in the future.
  
  By following these steps, you should be able to resolve the QG711 error and ensure that your classes are correctly defined in descending order.
