• What is the cause and solution for SAP error message CNVMBTRFC100 - Destination &1 in system &2 with wrong unicode setting. ?

  The SAP error message CNVMBTRFC100 indicates that there is an issue with the Unicode settings of the destination system specified in the error message. This typically occurs in scenarios involving data transfer between systems, especially during migrations or conversions where Unicode compatibility is crucial.
  Cause:
  The error is caused by a mismatch in Unicode settings between the source and target systems. Specifically, it indicates that the destination system (system &2) is not configured to handle Unicode data correctly, which can lead to data corruption or loss during transfer.
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check Unicode Settings:
  
  Verify the Unicode settings of both the source and destination systems. You can do this by checking the system parameters in transaction RZ10 or by using the SICF transaction to check the HTTP services.
  
  
  
  Adjust Destination System:
  
  If the destination system is not Unicode-enabled, you may need to convert it to a Unicode system. This process can be complex and may require assistance from SAP support or a qualified consultant.
  
  
  
  Modify RFC Destination:
  
  If the destination system is indeed Unicode-enabled, ensure that the RFC destination is correctly configured. You can check this in transaction SM59. Make sure that the connection type and settings are appropriate for Unicode data transfer.
  
  
  
  Test the Connection:
  
  After making the necessary adjustments, test the RFC connection to ensure that it is functioning correctly. You can do this in transaction SM59 by selecting the RFC destination and using the "Connection Test" option.
  
  
  
  Review SAP Notes:

  Related Information:
  
  Unicode in SAP: Unicode is a character encoding standard that allows for the representation of text in most of the world's writing systems. SAP systems can be either Unicode or non-Unicode, and it is essential to ensure compatibility when transferring data.
  RFC (Remote Function Call): RFC is a communication interface in SAP that allows for the calling of functions in a remote system. Proper configuration of RFC destinations is crucial for successful data transfer.
  SAP Migration Projects: If you are involved in a migration project, ensure that both source and target systems are compatible in terms of Unicode settings to avoid such errors.
  
  If the issue persists after following these steps, it may be necessary to engage SAP support for further assistance.
