• 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
