• What is the cause and solution for SAP error message FSSC_GENERIC012 - RFC destination for Mapped Logical System &1 could not be determined ?

  The SAP error message FSSC_GENERIC012 indicates that the system is unable to determine the RFC (Remote Function Call) destination for a mapped logical system. This typically occurs in scenarios involving cross-system communication, such as when using SAP Central Finance or when integrating multiple SAP systems.
  Cause:
  
  Missing or Incorrect Configuration: The logical system may not be properly configured in the SAP system. This can happen if the logical system name is not defined in the system or if the mapping between the logical system and the RFC destination is missing or incorrect.
  RFC Destination Not Defined: The RFC destination that corresponds to the logical system may not be created in the SAP system.
  Authorization Issues: There may be authorization issues preventing the system from accessing the required RFC destination.
  Transport Layer Issues: If the system is part of a transport layer, there may be issues with the transport configuration that prevent the logical system from being recognized.
  
  Solution:
  
  
  Check Logical System Configuration:
  
  Go to transaction SPRO and navigate to the relevant configuration for logical systems.
  Ensure that the logical system is defined correctly in the system.
  
  
  
  Define RFC Destination:
  
  Use transaction SM59 to check if the RFC destination for the logical system exists.
  If it does not exist, create a new RFC destination that points to the correct system.
  
  
  
  Mapping Configuration:
  
  Check the mapping configuration in the relevant application (e.g., Central Finance) to ensure that the logical system is correctly mapped to the RFC destination.
  This can often be found in the configuration settings for the specific application.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to access the RFC destination.
  Check the roles and authorizations assigned to the user.
  
  
  
  Transport Layer Configuration:
  
  If applicable, check the transport layer settings to ensure that the logical system is correctly recognized.
  
  
  
  System Logs:
  
  Review system logs (transaction SLG1) for any additional error messages or warnings that may provide more context about the issue.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SM59: To manage RFC destinations.
  SPRO: To access the configuration settings.
  SLG1: To view application logs.
  
  
  
  Documentation: Refer to SAP Help documentation for specific modules (like Central Finance) for detailed configuration steps.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide patches related to this error message.
  
  
  By following these steps, you should be able to identify and resolve the issue related to the RFC destination for the mapped logical system.
