• What is the cause and solution for SAP error message CNV_CDMC_CC021 - The user in the RFC connection is not of the type DIALOG ?

  The SAP error message CNV_CDMC_CC021 indicates that the user configured in the RFC (Remote Function Call) connection is not of the type DIALOG. This typically occurs when the system is trying to execute a function that requires a dialog user, but the user defined in the RFC connection is of a different type, such as a system user or service user.
  Cause:
  
  User Type: The user defined in the RFC connection is not a dialog user. Dialog users are interactive users who can log into the SAP system and perform transactions.
  RFC Configuration: The RFC connection may be incorrectly configured to use a non-dialog user.
  Authorization Issues: The user may not have the necessary authorizations to perform the required actions.
  
  Solution:
  
  
  Change User Type:
  
  Ensure that the user defined in the RFC connection is a dialog user. You can check this in transaction SU01 (User Maintenance) by looking at the user type.
  If the user is not a dialog user, you may need to create a new dialog user or change the existing user's type.
  
  
  
  Update RFC Connection:
  
  Go to transaction SM59 (RFC Destinations) and check the configuration of the RFC connection.
  Ensure that the user specified in the RFC connection is a dialog user.
  
  
  
  Check Authorizations:
  
  Verify that the dialog user has the necessary authorizations to perform the required actions. You can check this in transaction SU53 (Display Authorization Check) after attempting to execute the function.
  
  
  
  Testing:
  
  After making the necessary changes, test the RFC connection to ensure that the error is resolved.
