• What is the cause and solution for SAP error message RSAR649 - No RFC name for source system & (type &) created ?

  The SAP error message RSAR649 indicates that there is no RFC (Remote Function Call) name associated with a source system in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error typically arises when you are trying to extract data from a source system, and the system cannot find the necessary RFC connection to communicate with it.
  Cause:
  
  Missing RFC Destination: The RFC destination for the source system has not been created or is not correctly configured in the SAP system.
  Incorrect Source System Configuration: The source system may not be properly defined in the BW system, leading to the absence of an RFC name.
  Authorization Issues: The user may not have the necessary authorizations to access the source system or the RFC destination.
  Network Issues: There may be network connectivity issues preventing the SAP system from reaching the source system.
  
  Solution:
  
  
  Create or Check RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Check if the RFC destination for the source system exists. If it does not, create a new RFC destination.
  Ensure that the connection type is appropriate (e.g., TCP/IP) and that the target host and system number are correctly specified.
  
  
  
  Verify Source System Configuration:
  
  Go to transaction RSA1 (Data Warehousing Workbench).
  Navigate to the source systems and check if the source system is correctly defined.
  Ensure that the RFC destination is assigned to the source system.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to access the source system and the RFC destination.
  You may need to consult with your security team to verify and adjust the authorizations.
  
  
  
  Test Connectivity:
  
  In transaction SM59, you can test the RFC connection to ensure that it is working correctly.
  If there are issues, check network settings, firewalls, and ensure that the source system is up and running.
  
  
  
  Check Logs:
  
  Review the system logs for any additional error messages that might provide more context about the issue.
  Use transaction SLG1 to check application logs related to the source system.
  
  
  
  Related Information:
  
  RFC Destinations: These are used in SAP to define how systems communicate with each other. Proper configuration is crucial for data extraction and integration.
  Source System Configuration: In BW, source systems can be SAP or non-SAP systems, and each needs to be configured correctly to allow data extraction.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to your version of SAP BW or the source system you are working with.
  
  By following these steps, you should be able to resolve the RSAR649 error and establish a successful connection to your source system.
