• What is the cause and solution for SAP error message FINS_MAP020 - RFC execution rejected because RFC calls from gateway are disabled. ?

  The SAP error message FINS_MAP020 indicates that Remote Function Call (RFC) execution has been rejected because RFC calls from the gateway are disabled. This typically occurs in scenarios where an RFC-enabled function module is being called, but the system settings do not allow such calls.
  Cause:
  
  Gateway Settings: The SAP system may have been configured to disable RFC calls from the gateway for security or performance reasons.
  Authorization Issues: The user or system trying to execute the RFC may not have the necessary authorizations.
  System Configuration: The system may be configured to restrict certain types of RFC calls, either globally or for specific users or roles.
  
  Solution:
  
  
  Check Gateway Configuration:
  
  Use transaction SMGW to check the gateway settings. Ensure that the gateway is configured to allow RFC calls.
  Look for any settings that might restrict RFC calls, such as gw/allow_start or similar parameters in the instance profile.
  
  
  
  Review Authorization:
  
  Ensure that the user executing the RFC has the necessary authorizations. Check the roles assigned to the user and ensure they include the required permissions for RFC execution.
  Use transaction SU53 to analyze authorization failures after the error occurs.
  
  
  
  Modify Profile Parameters:
  
  If you have access to the system profile parameters, check for parameters related to RFC and gateway settings. You may need to adjust these settings to enable RFC calls.
  Parameters like rfc/enable or rfc/allow_start may need to be set to allow RFC calls.
  
  
  
  Consult Basis Team:
  
  If you do not have the necessary permissions to change the settings, consult your SAP Basis team. They can help you identify the issue and make the necessary changes.
  
  
  
  Check for System Notes:
  
  Sometimes, specific SAP Notes may address issues related to RFC calls. Check the SAP Support Portal for any relevant notes that might provide additional guidance or patches.
