This error indicates that an attempt was made to change a class or characteristic to a new class or characteristic that is identical to the existing one, which is not allowed.
  Cause:
  
  Identical Class/Characteristic: The most common cause of this error is that the user is trying to assign a class or characteristic that is already assigned to the object. The system recognizes that there is no change being made because the old and new classes are the same.

  Solution:
  
  Verify Class/Characteristic: Check the class or characteristic you are trying to assign. Ensure that it is indeed different from the existing one. If it is the same, there is no need to make the change.
  Select a Different Class/Characteristic: If you intended to change to a different class or characteristic, make sure to select the correct one that is not identical to the current one.
  Review the Process: If you are following a specific process or transaction, review the steps to ensure that you are not inadvertently repeating the same class assignment.
