• What is the cause and solution for SAP error message TK518 - Source client has been changed to & ?

  The SAP error message TK518 indicates that the source client for a transport request has been changed. This typically occurs when a transport request is created in one client and then the source client is modified, which can lead to inconsistencies in the transport request.
  Cause:
  
  Client Change: The source client of the transport request has been altered after the transport request was created. This can happen if the transport request is being moved between different clients or if there are changes in the configuration of the transport landscape.
  Transport Directory Issues: There may be issues with the transport directory or the transport management system that cause the source client to be misidentified.
  Manual Changes: Manual changes to the transport request or the client settings can lead to this error.
  
  Solution:
  
  Check Transport Request: Verify the transport request to ensure that it is correctly assigned to the intended source client. You can do this by checking the transport logs and the details of the transport request in transaction SE09 or SE10.
  Recreate Transport Request: If the transport request is not valid due to the client change, consider recreating the transport request in the correct source client.
  Client Consistency: Ensure that the client settings are consistent across the landscape. This includes checking the transport routes and ensuring that the source and target clients are correctly configured.
  Transport Management System: If the issue persists, check the transport management system configuration. You may need to consult with your Basis team to ensure that the transport directory and transport routes are correctly set up.
