Hello,

I am writing this blog post for the FTP connection to the SAP ABAP system. While I was configuring the SAP FTP, I haven’t found complete information in a single blog post, So I am writing this blog post.

PRE-REQUISITES:

  • FTP credentials.

  • SAP GUI credentials with authorization.

  • SAP OS access to check IP ports accessibility.

  • Network basic understanding.


STEP TO CONFIGURE FTP FOR THE SAP ABAP SYSTEM.



  • Check FTP server IP and network Port.

    • Note down the FTP IP and port provided by FTP/OS team.

    • Telnet FTP server IP on a specific port. The default port is 21.

    • Telnet Syntax (Linux & windows): telnet <IP> <PORT>



  • Check FTP is accessible from SAP system OS.

    • telnet 123.12.21.20 21








    • Make sure it will connect.






  • Add FTP server entry in SAP Table.

    • Maintain FTP entry in SAP table (SAPFTP_SERVERS_V) using tcode sm30

    • SAPFTP_SERVER_V is a client dependent table. Add entry in those specific clients who are going to connect to FTP.








    • Click on the Maintain button & click on the New Entries button.








    • Add IP address, PORT and Description.








    • After maintaining entry click on the save button.






  • Test FTP connection using SAP standard Program.

    • Execute SAP program rsftp002 using tcode SA38.








    • Click on the execute button and enter details.
















    • I am using RFC “SAPFTPA” as FTP is only accessible from the SAP server.







    • If the connection is not successful you get the error like below.








    • or like below.






 

 

 



    • If the connection is successful you will get the output like below.






All screenshots are captured by me.

  • The above procedure will also work for the ABAP systems.

  • Telnet is a very useful tool to check the service port and its accessibility from the target.


  • SAPFTP_SERVERS_V Table is used to store the information about the allowed FTP server.

    • Without entry in this table SAP will not able to establish the connection to the FTP server.

    • If maintain * in this table all FTP servers will be accessible.



  • FTP server by default runs on port 21, If the port is different so maintain that port in SAP_FTP_SERVER_V.

  • Program RSFTP002 is used to test FTP connection and run execute FTP command.



  • There are two RFC that we can use to access FTP.

    • SAPFTP uses frontend/Local computer internet to access the FTP server.

    • SAPFTPA uses backend/SAP server internet to access the FTP server.




Thank you !!!
