• What is the cause and solution for SAP error message TR751 - Source and target system must be different ?

  The SAP error message TR751 ("Source and target system must be different") typically occurs during transport operations when you are trying to transport objects from one system to another, but the source and target systems are incorrectly configured to be the same. This can happen in various scenarios, such as when using the Transport Management System (TMS) or during manual transport requests.
  Cause:
  
  Same System Configuration: The most common cause of this error is that the source and target systems are set to the same system in the transport request. This can happen if you mistakenly select the same system for both the source and target.
  Transport Request Configuration: The transport request may have been incorrectly configured, leading to an attempt to transport objects within the same system.
  Transport Layer Issues: There may be issues with the transport layer configuration that are causing the system to misinterpret the source and target systems.
  
  Solution:
  
  
  Check Transport Request: Review the transport request to ensure that the source and target systems are correctly defined. You can do this by:
  
  Going to the Transport Organizer (transaction code SE09 or SE10).
  Selecting the transport request and checking the details.
  Ensure that the target system is different from the source system.
  
  
  
  Correct Transport Layer: If the transport layer is incorrectly configured, you may need to adjust the settings:
  
  Go to transaction code STMS.
  Check the transport routes and ensure that the source and target systems are correctly defined.
  
  
  
  Use Correct Transport Method: If you are using a specific transport method (e.g., client transport), ensure that you are following the correct procedure for that method.
  
  
  Recreate Transport Request: If the transport request is corrupted or incorrectly set up, consider creating a new transport request and adding the objects again.
  
  
  Consult Documentation: If you are unsure about the configuration, refer to SAP documentation or consult with your SAP Basis team for assistance.
  
  
  Related Information:
  
  Transport Management System (TMS): Familiarize yourself with TMS, as it is crucial for managing transports between different SAP systems.
  Transport Layers: Understand how transport layers work in SAP and how they define the relationship between source and target systems.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to transport errors. You can search for notes in the SAP Support Portal.
  
  If the issue persists after trying the above solutions, it may be beneficial to engage with your SAP Basis team or SAP support for further troubleshooting.
