  Synchronize Versions: If there are multiple versions of the business object, ensure that the same version is being used in both the request and response.
  
  
  Update Integration Directory: If changes have been made to the business object or service interface, ensure that the Integration Directory is updated accordingly.
  
  
  Testing: After making the necessary changes, test the integration scenario again to ensure that the error is resolved.
