Error in FTP_CONNECT

Hi all,

I want to test a function module "FTP_CONNECT". I am passing below four mandatory parameters.

1. USER
2. PASSWORD
3. HOST
4. RFC_DESTINATION

and I am getting an error "User XXXX has no access authorization for computer XXXX. Message no. 04202"

My doubts are as follows:

1. Here, what should I pass to the import parameter "User" and "Password"?

    Should I pass my SAP user ID credentialsOR Computer (Logon user) credentials ?

2. And when HOST is a different FTP server that I want to connect to then Do I need to make any modification to the host file located at C:\Windows\System32\drivers\etcpath?

3. What is table "SAPFTP_SERVERS"? When it is updated?

Kindly reply at the earliest. All sort of reply and comments will be appreciated.

Thanks,

NG
