• What is the cause and solution for SAP error message RSAR678 - RFC name for source system & (type &) changed ?

  The SAP error message RSAR678 indicates that there is a change in the RFC (Remote Function Call) name for a source system in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This typically occurs when the source system's configuration has been modified, which can lead to issues in data extraction or data loading processes.
  Cause:
  
  RFC Name Change: The most common cause of this error is that the RFC destination name for the source system has been changed or is no longer valid.
  Source System Configuration: Changes in the source system configuration, such as changes in the system ID (SID) or the logical system name.
  Transport Issues: If the source system was transported from one environment to another (e.g., from development to production), the RFC destination may not have been properly configured in the new environment.
  Network Issues: Network connectivity issues or changes in the network configuration can also lead to this error.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Verify the RFC destination for the source system. Ensure that the name is correct and that it points to the right system.
  Test the connection to ensure that it is working properly.
  
  
  
  Update Source System Configuration:
  
  Go to transaction RSA1 (Data Warehousing Workbench).
  Navigate to the source system and check its configuration.
  If the RFC name has changed, update the source system configuration to reflect the new RFC name.
  
  
  
  Check Logical System Name:
  
  Ensure that the logical system name in the source system matches the one defined in the BW system.
  You can check this in transaction BD54 (Maintain Logical System).
  
  
  
  Transport Configuration:
  
  If the source system was transported, ensure that all necessary configurations were included in the transport request.
  Re-import the transport request if necessary.
  
  
  
  Check for Network Issues:
  
  Ensure that there are no network issues preventing the connection to the source system.
  Check firewall settings, VPN configurations, or any other network-related settings.
  
  
  
  Recreate the Source System:
  
  If the issue persists, consider deleting and recreating the source system in BW.
