This error is related to the non-uniqueness of a parameter value that has been defined in the Customizing settings.
  Cause:
  
  Non-Unique Parameter Value: The error arises when a parameter (in this case, NCODE_NON_UNIQUE) has been defined with a value that is not unique within the system. This can happen if multiple entries exist for the same parameter value, which can lead to ambiguity in processing.

  Solution:
  
  
  Check Customizing Settings: 
  
  Go to the relevant Customizing transaction (e.g., SPRO) and navigate to the area where the parameter NCODE_NON_UNIQUE is defined.
  Look for duplicate entries or conflicting values for this parameter.
  Ensure that each parameter value is unique and does not conflict with others.
  
  
  
  Modify or Delete Duplicates:
  
  If you find duplicate entries, you will need to either modify them to ensure uniqueness or delete the unnecessary duplicates.
  Make sure to document any changes you make for future reference.
  
  
  
  Transport Changes: If you are working in a development environment, ensure that any changes made are transported to the quality and production environments as needed.
  
  
  Testing: After making the necessary changes, perform testing to ensure that the error no longer occurs and that the system behaves as expected.
