• What is the cause and solution for SAP error message TK165 - Source client = target client not possible for transports ?

  The SAP error message TK165 ("Source client = target client not possible for transports") typically occurs during the transport of objects between clients in an SAP system. This error indicates that the source client and the target client are the same, which is not allowed for transport requests.
  Cause:
  The error arises when you attempt to transport a request from a client to itself. In SAP, transport requests are meant to move changes from one client to another (e.g., from a development client to a quality assurance client or production client). Transporting to the same client does not make sense, as there would be no change in the system.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Transport Request: Ensure that you are not trying to transport a request to the same client. Verify the source and target clients in the transport management system (STMS).
  
  
  Select the Correct Target Client: If you intended to transport the request to a different client, make sure to select the correct target client during the transport process.
  
  
  Use the Correct Transport Method: If you need to apply changes in the same client, consider using other methods such as direct changes in the client or using the transport organizer (SE09/SE10) to release the changes without transport.
  
  
  Review Transport Routes: If you are working in a landscape with multiple clients, ensure that the transport routes are correctly configured in the Transport Management System (STMS).
  
  
  Check for Configuration Issues: If you believe you are not trying to transport to the same client, check for any configuration issues in the transport landscape that might be causing this error.
