• What is the cause and solution for SAP error message CNV_CDOP_CC021 - The user in the RFC Connection is not of the type DIALOG ?

  The SAP error message CNV_CDOP_CC021 indicates that there is an issue with the user type in the RFC (Remote Function Call) connection. Specifically, the error states that the user configured for the RFC connection is not of the type DIALOG. This can occur in scenarios where a background job or a non-interactive process is trying to use an RFC connection that requires a dialog user.
  Cause:
  
  User Type: The user defined in the RFC connection is likely a system user or a communication user, which does not have dialog capabilities. Dialog users are typically used for interactive sessions.
  RFC Configuration: The RFC connection may be configured incorrectly, pointing to a user that is not suitable for the operation being performed.
  Authorization Issues: The user may not have the necessary authorizations to perform the required actions in the system.
  
  Solution:
  
  
  Change User Type:
  
  Go to the transaction SU01 (User Maintenance) in SAP.
  Enter the user ID that is being used in the RFC connection.
  Check the user type. If it is set to "System" or "Communication", change it to "Dialog".
  Save the changes.
  
  
  
  Review RFC Connection:
  
  Go to transaction SM59 (RFC Destinations).
  Find the relevant RFC connection and check the settings.
  Ensure that the user specified in the RFC connection is a dialog user.
  
  
  
  Check Authorizations:
  
  Ensure that the dialog user has the necessary authorizations to perform the required actions in the system.
  You may need to assign appropriate roles or profiles to the user.
  
  
  
  Testing:
  
  After making the changes, test the RFC connection to ensure that the error is resolved.
  You can use the "Test Connection" feature in transaction SM59 to verify that the connection works as expected.
