• What is the cause and solution for SAP error message MDG_GN_RFC023 - No authorization for the RFC ?

  The SAP error message MDG_GN_RFC023: No authorization for the RFC typically indicates that the user attempting to execute a Remote Function Call (RFC) does not have the necessary authorizations to perform the requested operation. This can occur in various scenarios, especially in SAP Master Data Governance (MDG) environments where RFCs are commonly used for data synchronization and integration.
  Cause:
  
  Missing Authorizations: The user does not have the required authorizations assigned in their user profile to execute the specific RFC function module.
  Role Assignment: The roles assigned to the user may not include the necessary permissions for the RFC being called.
  Profile Issues: The user profile may not be correctly configured, or the necessary authorization objects are not included in the profile.
  System Configuration: There may be system-level restrictions or configurations that prevent the execution of the RFC.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to analyze the authorization check. This will show which authorization objects are missing.
  Review the user’s roles and profiles in transaction SU01 or PFCG to ensure that the necessary authorizations are included.
  
  
  
  Assign Required Roles:
  
  If the required roles are missing, assign the appropriate roles that include the necessary authorizations for the RFC function module.
  Ensure that the roles are properly activated and that the user has been assigned to them.
  
  
  
  Authorization Objects:
  
  Identify the specific authorization objects required for the RFC. This can often be found in the documentation for the RFC function module or by consulting with your SAP security team.
  Common authorization objects for RFCs include S_RFC, S_RFC_ADM, and others depending on the specific function being called.
  
  
  
  Consult with Security Team:
  
  If you are not able to resolve the issue, consult with your SAP security team or basis team. They can help analyze the authorization issues and make necessary adjustments.
  
  
  
  Testing:
  
  After making changes to roles or authorizations, test the RFC call again to ensure that the issue is resolved.
