• What is the cause and solution for SAP error message KU379 - No more characteristics need defining for the characteristic structure ?

  The SAP error message KU379 ("No more characteristics need defining for the characteristic structure") typically occurs in the context of defining characteristics for a characteristic structure in SAP's classification system. This error indicates that you are trying to add more characteristics to a structure that has already been fully defined.
  Cause:
  
  Exceeding Limits: You may be attempting to add additional characteristics to a characteristic structure that has already reached its maximum limit.
  Incorrect Process: The process of defining characteristics may not be followed correctly, leading to an attempt to add characteristics when none are needed.
  Misunderstanding of Structure: There may be a misunderstanding of the characteristic structure's purpose or its current state, leading to confusion about whether more characteristics can be added.
  
  Solution:
  
  Review Existing Characteristics: Check the existing characteristics in the characteristic structure to ensure that you are not trying to add duplicates or unnecessary characteristics.
  Check Limits: Verify if the characteristic structure has a limit on the number of characteristics it can hold. If it has reached this limit, you will need to modify the existing structure rather than adding new characteristics.
  Modify Existing Characteristics: If you need to change the characteristics, consider modifying or deleting existing ones instead of adding new ones.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific limits and processes related to characteristic structures.
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for assistance.
