• What is the cause and solution for SAP error message QS079 - Reference to the class characteristic will not be copied ?

  The SAP error message QS079 ("Reference to the class characteristic will not be copied") typically occurs in the context of Quality Management (QM) when you are trying to copy or transfer characteristics from one class to another, particularly when dealing with class characteristics in classification systems.
  Cause:
  The error message QS079 is triggered when you attempt to copy a characteristic that is defined as a reference characteristic in a class. Reference characteristics are those that are linked to a class but do not have their own independent values; instead, they refer to characteristics defined in another class. Since these characteristics do not have their own data, they cannot be copied directly.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Characteristic Definition: Verify if the characteristic you are trying to copy is indeed a reference characteristic. You can do this by checking the characteristic settings in the class.
  
  
  Use Non-Reference Characteristics: If you need to copy characteristics, ensure that you are selecting non-reference characteristics. You can create new characteristics in the target class if necessary.
  
  
  Manual Adjustment: If you need the reference characteristic in the new class, you may need to manually create it in the target class and link it appropriately.
  
  
  Review Class Hierarchy: Ensure that the class hierarchy is correctly set up and that the characteristics you are trying to copy are compatible with the target class.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on handling class characteristics and copying processes.
