Error using 'FTP_CONNECT' IN RFC

[Former Member]

Hello,

I'm calling an RFC from system A to system B.

In system B the RFC must read a flat file via FTP using FM 'FTP_CONNECT' and 'FTP_SERVER_TO_R3'.

The connection parameters (user, password, host...) are incrusted in the code. When I test the RFC in local machine it works perfectly, it reads the file and returns the result. But when I call it remotely it doesn't works fine.

I've generated a log of the execution and I've found that the problem is when I call 'FTP_CONNECT'. It gives me an EXCEPTION (NOT_CONNECED) but I don't know why... The parameters are the same when I test and when I call it remotely...

What can I do to solve that?

Check this sample code:-

REPORT ZKBTST32 LINE-SIZE 132.
*-----------------------------------------------------------------------
* Test SAP FTP functions
*-----------------------------------------------------------------------

DATA: BEGIN OF MTAB_DATA OCCURS 0,
LINE(132) TYPE C,
END OF MTAB_DATA.

DATA: MC_PASSWORD(20) TYPE C,
MI_KEY TYPE I VALUE 26101957,
MI_PWD_LEN TYPE I,
MI_HANDLE TYPE I.

START-OF-SELECTION.

MC_PASSWORD = 'password'.

DESCRIBE FIELD MC_PASSWORD LENGTH MI_PWD_LEN.

*-- FTP_CONNECT requires an encrypted password to work
CALL 'AB_RFC_X_SCRAMBLE_STRING'
     ID 'SOURCE' FIELD MC_PASSWORD ID 'KEY' FIELD MI_KEY
     ID 'SCR' FIELD 'X' ID 'DESTINATION' FIELD MC_PASSWORD
     ID 'DSTLEN' FIELD MI_PWD_LEN.

CALL FUNCTION 'FTP_CONNECT'
     EXPORTING
       USER            = 'userid'
       PASSWORD        = MC_PASSWORD
       HOST            = 'servername'
       RFC_DESTINATION = 'SAPFTP'
     IMPORTING
       HANDLE          = MI_HANDLE
     EXCEPTIONS
       NOT_CONNECTED   = 1
       OTHERS          = 2.

CHECK SY-SUBRC = 0.

CALL FUNCTION 'FTP_COMMAND'
     EXPORTING
       HANDLE = MI_HANDLE
       COMMAND = 'dir'
     TABLES
       DATA = MTAB_DATA
     EXCEPTIONS
       TCPIP_ERROR = 1
       COMMAND_ERROR = 2
       DATA_ERROR = 3
       OTHERS = 4.

IF SY-SUBRC = 0.
  LOOP AT MTAB_DATA.
    WRITE: / MTAB_DATA.
  ENDLOOP.
ELSE.
* do some error checking.
ENDIF.

CALL FUNCTION 'FTP_DISCONNECT'
     EXPORTING
       HANDLE = MI_HANDLE
     EXCEPTIONS
       OTHERS = 1.

Thanks,

Hi Naren,

I already know how to use FTP_CONNECT. I've programmed my Function module and it works OK. The problem is when I execute it remotely, I don't know why but FTP_CONNECT gives me an error when I use it via RFC...

Nobody knows why FTP_CONNECT doesn't work?
