• What is the cause and solution for SAP error message SB632 - No RFC authorization ?

  The SAP error message SB632 "No RFC authorization" typically indicates that the user does not have the necessary authorizations to perform Remote Function Call (RFC) operations. This can occur in various scenarios, such as when trying to execute a function module remotely or when accessing a system via RFC.
  Cause:
  
  Missing Authorizations: The user does not have the required authorizations in the target system for the RFC call.
  Profile Issues: The user profile may not include the necessary roles or authorizations for RFC access.
  Incorrect User Mapping: If the RFC connection is set up with a specific user, that user may not have the required permissions.
  System Configuration: The RFC destination may not be configured correctly, or the target system may have restrictions on RFC calls.
  
  Solution:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to see what authorizations are missing.
  Review the user’s roles and profiles in transaction PFCG to ensure that the necessary authorizations for RFC are included.
  
  
  
  Assign Necessary Roles:
  
  If the user lacks the required roles, assign the appropriate roles that include RFC authorizations. Common roles include those related to system administration or specific application functions.
  
  
  
  Review RFC Destination Settings:
  
  Check the RFC destination settings in transaction SM59. Ensure that the connection is set up correctly and that the user credentials used for the connection have the necessary authorizations.
  
  
  
  Test the RFC Connection:
  
  Use the Test Connection feature in transaction SM59 to verify that the RFC connection works as expected.
  
  
  
  Consult Security Team:
  
  If you are not authorized to make changes to user roles or profiles, contact your SAP security team for assistance.
  
  
  
  Check for System Restrictions:
  
  Ensure that there are no system-wide restrictions or settings that prevent RFC calls from being executed.
