• What is the cause and solution for SAP error message 0D651 - RFC cannot be executed: no authorizations for starting ?

  The SAP error message "0D651 RFC cannot be executed: no authorizations for starting" typically indicates that the user attempting to execute a Remote Function Call (RFC) does not have the necessary authorizations to perform that action. This can occur in various scenarios, such as when a user tries to call a function module or execute a transaction remotely.
  Cause:
  
  Missing Authorizations: The user does not have the required authorizations assigned in their user profile to execute the specific RFC function.
  Role Assignment: The roles assigned to the user may not include the necessary permissions for the RFC call.
  Profile Issues: The user’s authorization profile may not be correctly configured to allow the execution of the RFC.
  System Configuration: There may be system-level restrictions or configurations that prevent the execution of certain RFCs.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction SU01 to check the user’s authorizations.
  Review the roles assigned to the user and ensure that they include the necessary permissions for the RFC function being called.
  
  
  
  Assign Necessary Roles:
  
  If the user lacks the required roles, assign the appropriate roles that include the necessary authorizations for the RFC execution.
  You may need to work with your SAP security team to ensure that the correct roles are assigned.
  
  
  
  Use Transaction SU53:
  
  After encountering the error, use transaction SU53 to analyze the authorization check that failed. This transaction provides a detailed report of the authorization checks that were performed and can help identify which specific authorization is missing.
  
  
  
  Review Authorization Objects:
  
  Identify the specific authorization objects that are required for the RFC call. This information can often be found in the documentation for the function module or transaction being called.
  Ensure that the user has the necessary authorizations for these objects.
  
  
  
  Consult with Security Team:
  
  If you are unable to resolve the issue, consult with your SAP security team or basis team. They can provide assistance in reviewing and adjusting user roles and authorizations.
  
  
  
  Related Information:
  
  Authorization Objects: Common authorization objects related to RFC calls include S_RFC, S_RFC_ADM, and S_USER_AUTH.
  Transaction Codes:
  
  SU01: User Maintenance
  PFCG: Role Maintenance
  SU53: Display Authorization Check
  
  
  Documentation: Refer to SAP Help documentation for specific function modules or transactions to understand the required authorizations.
  
  By following these steps, you should be able to identify and resolve the authorization issue causing the RFC execution error.
