• What is the cause and solution for SAP error message EPIC_EXAMPLE_CN_IMPL026 - RFC connection haven't configured! ?

  The SAP error message "EPIC_EXAMPLE_CN_IMPL026 RFC connection hasn't configured!" typically indicates that there is an issue with the configuration of an RFC (Remote Function Call) connection in your SAP system. This error can occur in various scenarios, such as when trying to execute a function module that requires an RFC connection to another SAP system or to an external system.
  Cause:
  
  Missing RFC Destination: The RFC destination that the program or function module is trying to use has not been defined in the SAP system.
  Incorrect Configuration: The RFC destination may exist but is not configured correctly (e.g., incorrect connection parameters, wrong target system).
  Authorization Issues: The user executing the function may not have the necessary authorizations to use the RFC connection.
  Network Issues: There may be network connectivity issues preventing the SAP system from reaching the target system.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Look for the RFC destination that is being referenced in the error message.
  If it does not exist, create a new RFC destination with the appropriate settings.
  If it exists, verify that the connection parameters (such as target host, system number, client, user, password, etc.) are correct.
  
  
  
  Test the Connection:
  
  In transaction SM59, select the RFC destination and use the "Test Connection" button to check if the connection is working properly.
  If the test fails, review the error message for more details and troubleshoot accordingly.
  
  
  
  Check Authorizations:
  
  Ensure that the user executing the function has the necessary authorizations to use the RFC connection.
  You may need to check the roles and profiles assigned to the user.
  
  
  
  Review Network Configuration:
  
  Ensure that there are no firewall or network issues preventing the SAP system from connecting to the target system.
  Check if the target system is up and running.
  
  
  
  Consult Documentation:
  
  If the RFC connection is part of a specific application or module, consult the relevant SAP documentation for any additional configuration steps that may be required.
