This error can arise due to several reasons, and here are some potential causes, solutions, and related information:
  Causes:
  
  User Type Mismatch: The user being used to execute the RFC call may not have the appropriate authorizations or may not be of the correct user type (e.g., dialog user vs. service user).
  Service User Configuration: If a service user is being used, it may not be configured correctly in the system.
  Authorization Issues: The user may lack the necessary authorizations to execute the requested operation.

  Review User Authorizations: Verify that the user has the necessary authorizations to perform the requested operation. You can use transaction SU53 to analyze authorization failures.
  Validate RFC Destination: Check the configuration of the RFC destination using transaction SM59. Ensure that the destination is correctly set up and that the credentials are valid.
  Test Connection: Use the "Test Connection" feature in transaction SM59 to ensure that the RFC destination can be reached and that the credentials are working.
