• What is the cause and solution for SAP error message 04215 - WIN16: FTP can only be started once ?

  The SAP error message "04215 WIN16: FTP can only be started once" typically occurs when there is an attempt to start an FTP (File Transfer Protocol) session in SAP, but the system detects that an FTP session is already active. This can happen in various scenarios, such as when a user tries to initiate multiple FTP connections simultaneously or if a previous FTP session did not close properly.
  Cause:
  
  Multiple FTP Sessions: The most common cause is that an FTP session is already running, and the system does not allow multiple instances of FTP to be initiated.
  Improper Closure of Previous Session: If a previous FTP session was not terminated correctly, it may still be considered active by the system.
  Configuration Issues: There may be configuration settings in the SAP system that limit the number of concurrent FTP sessions.
  
  Solution:
  
  Check Active Sessions: Verify if there are any active FTP sessions. You can do this by checking the transaction codes related to FTP or by looking at the system logs.
  Terminate Existing Session: If you find an active FTP session that is no longer needed, terminate it properly. This can often be done through the SAP GUI or by using specific transaction codes.
  Restart the SAP System: If you are unable to identify or terminate the active session, restarting the SAP system may help clear any lingering sessions.
  Review Configuration: Check the configuration settings related to FTP in your SAP system. Ensure that the settings allow for the desired number of concurrent FTP sessions.
  Consult Documentation: Refer to SAP documentation or support resources for any specific notes or patches related to FTP functionality.
