• What is the cause and solution for SAP error message RSAR673 - Destination &1 has incorrect Unicode setting; adjust it to destination ?

  The SAP error message RSAR673 indicates that there is a mismatch in the Unicode settings between the source and target systems in a Remote Function Call (RFC) destination. This typically occurs when you are trying to connect to a system that has different Unicode settings than what is expected.
  Cause:
  
  Unicode Mismatch: The destination system is not configured to support Unicode, or it is set up incorrectly. This can happen if the source system is Unicode-enabled and the target system is not, or vice versa.
  Incorrect Configuration: The RFC destination may not be properly configured in the SAP system, leading to incorrect Unicode settings being used.
  
  Solution:
  To resolve the RSAR673 error, follow these steps:
  
  
  Check Unicode Settings:
  
  Verify the Unicode settings of both the source and target systems. You can do this by checking the system parameters in transaction RZ10 or by using the SICF transaction to check the HTTP service settings.
  Ensure that both systems are either Unicode or non-Unicode.
  
  
  
  Adjust RFC Destination:
  
  Go to transaction SM59 to check the configuration of the RFC destination that is causing the error.
  Select the relevant RFC destination and click on "Technical Settings".
  Ensure that the "Unicode" checkbox is set correctly based on the Unicode status of the target system. If the target system is Unicode, ensure that the checkbox is checked; if it is non-Unicode, ensure that it is unchecked.
  
  
  
  Test the Connection:
  
  After making the necessary adjustments, test the RFC connection by using the "Connection Test" option in SM59. This will help confirm that the settings are correct and that the connection can be established without errors.
  
  
  
  Check for Other Issues:
  
  If the error persists, check for other potential issues such as network connectivity, authorization problems, or other configuration settings that might be affecting the RFC connection.
