Send file generated of SAP transaction to Filezilla FTP

Hi,

I must to make a program to send out the generated file by a SAP FI standard transaction to an external Filezilla FTP. I know the server of this Filezilla FTP (it's a IP, not a URL), the user and the password.

I've checked the program RSFTP002, to check out the connection, but it says: "User has no authorization for computer". I've put the user, password, host (it's a IP, not a URL, I don't know if the issue is here..), and the RFC destination SAPFTP.

Could you know what's the issue?.

Thanks.
