• What is the cause and solution for SAP error message CNVMBTRFC007 - All RFC Destinations are working but not supported by SAP (see long text) ?

  The SAP error message CNVMBTRFC007 indicates that there is an issue with the RFC (Remote Function Call) destinations in your SAP system. Specifically, the message states that while all RFC destinations are operational, they are not supported by SAP for the specific operation you are trying to perform. This error is often encountered during data migration or system conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.
  Cause:
  
  Unsupported RFC Destinations: The RFC destinations configured in your system may not be compatible with the specific SAP functionality or migration process you are attempting to execute.
  Configuration Issues: There may be misconfigurations in the RFC destinations, such as incorrect parameters or missing authorizations.
  Version Compatibility: The RFC destinations may point to systems that are not on the required version or do not have the necessary components installed.
  Network Issues: Although the destinations are operational, there may be underlying network issues that prevent proper communication.
  
  Solution:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 and review the configuration of the RFC destinations.
  Ensure that the destinations are correctly set up and that the connection parameters (like target host, system number, client, etc.) are accurate.
  
  
  
  Verify System Compatibility:
  
  Ensure that the target systems (RFC destinations) are compatible with the source system and support the required operations.
  Check the SAP Notes and documentation for any specific requirements regarding the versions of the systems involved.
  
  
  
  Test RFC Connections:
  
  Use the Connection Test feature in transaction SM59 to verify that the RFC destinations can be reached and are functioning correctly.

  Check Authorizations:
  
  Ensure that the user credentials used for the RFC connections have the necessary authorizations to perform the required operations.
