• What is the cause and solution for SAP error message CM_EXPERT030 - RFC-Destination &1 is Non-Unicode (see SAP-Note 2452961) ?

  The SAP error message CM_EXPERT030 indicates that the RFC (Remote Function Call) destination specified is non-Unicode. This can lead to issues when trying to connect to or communicate with systems that expect Unicode data. The error message suggests that the RFC destination is not configured to handle Unicode data, which can be problematic in environments where Unicode is required.
  Cause:
  The primary cause of this error is that the RFC destination you are trying to use is set up as a non-Unicode destination. This can happen if:
  
  The destination was created in a system that does not support Unicode.
  The configuration of the RFC destination does not match the requirements of the calling program or system.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in your SAP system.
  Locate the RFC destination that is causing the error.
  Check the settings and ensure that the destination is configured correctly.
  
  
  
  Create or Modify the RFC Destination:
  
  If the RFC destination is non-Unicode, you may need to create a new RFC destination that is Unicode-enabled.
  When creating a new destination, ensure that the target system is set up to support Unicode.
  
  
  
  Refer to SAP Note 2452961:
  
  This SAP Note provides specific guidance and recommendations regarding the error message CM_EXPERT030. It may contain additional details on how to configure your RFC destination properly.
  
  
  
  Test the Connection:
  
  After making changes, use the "Test Connection" feature in transaction SM59 to verify that the RFC destination is now working correctly and is able to handle Unicode data.
  
  
  
  Check for System Compatibility:
  
  Ensure that both the source and target systems are compatible in terms of character encoding. If one system is Unicode and the other is not, you may need to address this at the application level.
  
  
  
  Related Information:
  
  Unicode vs. Non-Unicode: Unicode is a character encoding standard that allows for the representation of text in most of the world's writing systems. Non-Unicode systems may not support certain characters, leading to data loss or corruption.
  SAP Notes and Documentation: Always refer to the latest SAP Notes and documentation for updates and best practices regarding RFC configurations and Unicode support.
  SAP Community and Forums: Engaging with the SAP community can provide additional insights and solutions from other users who may have encountered similar issues.
