  Cause:
  This error typically occurs when a user tries to maintain or change a characteristic or function in a way that is restricted by the system. Specifically, the function or characteristic you are attempting to modify is either:

  Restricted by authorization or role settings.
  
  In many cases, this message appears in the context of Classification (CL30N, CL20N), Variant Configuration, or when maintaining characteristics and their values in SAP Logistics or SAP Variant Configuration.

  Check Authorizations:
  
  Ensure your user has the necessary authorizations to maintain the characteristic or function.
  Check roles and profiles assigned to your user.
