  Incorrect Operation Number: The operation number specified in the error message may not exist or may be incorrect, leading to the inability to find the transformation to modify.
  
  
  Solution:
  To resolve the NRSCNV129 error, you can take the following steps:

  Verify Authorizations: Ensure that your user account has the necessary authorizations to modify the transformation. You may need to consult with your SAP security team to verify and adjust your roles.
  
  
  Check Operation Number: Double-check the operation number you are using. Ensure that it is correct and corresponds to an existing transformation.
  
  
  Technical Support: If the issue persists, consider reaching out to your SAP Basis or technical support team. They can help investigate any underlying technical issues that may be causing the error.
  
  
  Restart the Session: Sometimes, simply logging out and logging back into the SAP system can resolve temporary issues.
