• What is the cause and solution for SAP error message /BDL/D-401 - System Failure - check RFC-Authorizations ?

  The SAP error message /BDL/D-401 System Failure - check RFC-Authorizations typically indicates an issue with Remote Function Call (RFC) authorizations in the SAP system. This error can occur when a user or system trying to execute a function module or transaction does not have the necessary authorizations to perform the action, particularly in a distributed environment where RFCs are used to communicate between different SAP systems.
  Causes:
  
  Missing Authorizations: The user or system does not have the required authorizations to execute the RFC function.
  Incorrect User Mapping: The user credentials used for the RFC connection may not be correctly mapped or may not have the necessary roles assigned.
  Profile Issues: The user profile may not include the necessary authorizations for the specific function being called.
  Network Issues: Sometimes, network issues can lead to failures in RFC calls, although this is less common for authorization-related errors.
  Configuration Issues: Incorrect configuration of the RFC destination or the related settings in the SAP system.
  
  Solutions:
  
  
  Check User Authorizations:
  
  Use transaction SU01 to check the user profile and ensure that the user has the necessary roles and authorizations assigned.
  Use transaction SU53 immediately after the error occurs to analyze the authorization check and identify missing authorizations.
  
  
  
  Review RFC Destination:
  
  Use transaction SM59 to check the configuration of the RFC destination. Ensure that the destination is correctly set up and that the user credentials are valid.
  Test the RFC connection from SM59 to ensure it is working properly.
  
  
  
  Assign Missing Roles:
  
  If specific authorizations are missing, assign the necessary roles to the user or system that is trying to execute the RFC call.
  
  
  
  Check for Profile Parameters:
  
  Ensure that the user profile parameters are correctly set up and that there are no restrictions that could be causing the failure.
  
  
  
  Consult Logs:
  
  Check the system logs (transaction SM21) for any additional error messages or information that could provide more context about the failure.
  
  
  
  Contact Basis Team:
  
  If the issue persists, it may be necessary to involve the SAP Basis team to investigate further, especially if it involves system-level configurations or network issues.
