  Identify the Change Number: Determine the appropriate change number that corresponds to the changes you want to make. This may involve consulting with your change management process or system.

  Input the valid change number that you have identified.
  
  
  
  Save the Changes: After entering the change number, proceed to save your changes. The system should now allow you to proceed without raising the error.
