• What is the cause and solution for SAP error message TB520 - Comparison object is cross-client. Systems are identical ?

  The SAP error message TB520 ("Comparison object is cross-client. Systems are identical") typically occurs during a transport or comparison process in SAP, particularly when using the Transport Management System (TMS) or during client comparisons. This error indicates that the system is trying to compare or transport objects that are defined as cross-client, but the systems being compared are identical in terms of those objects.
  Cause:
  
  Cross-Client Objects: The error arises because the object being compared or transported is a cross-client object (e.g., certain configuration settings, data dictionary objects, etc.) that should be the same across all clients in the system.
  Identical Systems: The systems being compared are identical, meaning that there are no differences in the cross-client objects, which leads to the error message.
  
  Solution:
  
  Ignore the Comparison: If the systems are indeed identical and the objects are cross-client, you can safely ignore this error. It indicates that there are no differences to be transported or compared.
  Check Transport Requests: Ensure that you are not trying to transport cross-client objects unnecessarily. If you are, you may want to adjust your transport requests accordingly.
  Review Configuration: If you believe there should be differences, review the configuration settings in both systems to ensure they are set up correctly.
  Use Client-Specific Objects: If you need to make changes that are client-specific, ensure that you are working with client-specific objects rather than cross-client ones.
  
  Related Information:
  
  Cross-Client vs. Client-Specific: In SAP, objects can be either cross-client (shared across all clients) or client-specific (unique to a particular client). Understanding the difference is crucial for effective transport management.
  Transport Management System (TMS): Familiarize yourself with TMS and how it handles transport requests, especially regarding cross-client objects.
  SAP Notes: Check SAP Notes for any updates or specific guidance related to the TB520 error. SAP frequently updates its documentation and provides solutions for known issues.
