Data transfer through FTP

[Former Member]

HI Friends,

Can any one tell me what is FTP ???And how we use FTP for data transfer????

[Former Member]

FTP is a file transfer protocol for exchanging files over any TCP/IP based network to manipulate files on another computer on that network regardless of which operating systems are involved (if the computers permit FTP access).

Hi Vibha,

Could u be more clear how we use FTP in our program to transfer the data???

You can use FTP by writing a small script at the operating system level, not from within SAP. For example, in Windows NT, enter appropriate commands in a text file opened with Notepad.

To FTP using ABAP, you can have a look at the standard program 'RSEPSFTP'.

Here is an example of how to FTP a file from the Application

server to a remote server using standard SAP functions.

REPORT Ztestftp 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.

Also here is another one.

DATA: W_USER(12) TYPE C ,

W_PWD(20) TYPE C ,

W_HOST(64) TYPE C.

DATA: HDL TYPE I,

KEY TYPE I VALUE 26101957,

DSTLEN TYPE I.

DATA: BEGIN OF RESULT OCCURS 0,

LINE(100) TYPE C,

END OF RESULT.

DESCRIBE FIELD PWD LENGTH DSTLEN.

CALL 'AB_RFC_X_SCRAMBLE_STRING'

ID 'SOURCE' FIELD PWD ID 'KEY' FIELD KEY

ID 'SCR' FIELD 'X' ID 'DESTINATION' FIELD PWD

ID 'DSTLEN' FIELD DSTLEN.

CALL FUNCTION 'FTP_CONNECT'

EXPORTING

USER = USER

PASSWORD = PWD

HOST = HOST

RFC_DESTINATION = 'SAPFTP'

IMPORTING

HANDLE = HDL.

LOOP AT COMMANDS.

IF COMMANDS NE ' '.

CALL FUNCTION 'FTP_COMMAND'

EXPORTING

HANDLE = HDL

COMMAND = COMMANDS

TABLES

DATA = RESULT

EXCEPTIONS

COMMAND_ERROR = 1

TCPIP_ERROR = 2.

LOOP AT RESULT.

WRITE AT / RESULT-LINE.

IF RESULT CS 'error'.

RAISE NO_SUCH_FILE.

ENDIF.

ENDLOOP.

REFRESH RESULT.

ENDIF.

ENDLOOP.

CALL FUNCTION 'FTP_DISCONNECT'

EXPORTING

HANDLE = HDL.

I hope it helps.

Thanks,

Vibha

Through FTP you can send any kind of file to a remote FTP server.You have to call the FMs in the following sequence.

1.'FTP_CONNECT' : To establish a connection to the FTP server. You have to pass the IP address of the FTP server along with the user id and password.

2.FTP_COMMAND: pass the filename with path which you want to transfer.

3.FTP_DISCONNECT : Disconnect the connection

[manubhutani]

some function modules for the same and their uses

dont forget to award points

1) HTTP_SCRAMBLE --> It will change the Password to the FTP format

2) FTP_CONNECT --> It will conect to the FTP server (We need to Provide the IP address)

3) FTP_R3_TO_SERVER --> This SAP R3 to Other Server and we need to pass the commands in this one

4) FTP_DISCONNECT --> It will disconent the FTP Conection

5) RFC_CONNECTION_CLOSE --> It wil close the Entire lick and Application

Here is the Sample program for FTP

codeREPORT ZFTPSAP LINE-SIZE 132.

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.

Your SAP-UNIX FTP password (case sensitive)

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

Your SAP-UNIX FTP user name (case sensitive)

USER = 'userid'

PASSWORD = MC_PASSWORD

Your SAP-UNIX server host name (case sensitive)

HOST = 'unix-host'

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.

WRITE: / 'Error in FTP Command'.

ENDIF.

CALL FUNCTION 'FTP_DISCONNECT'

EXPORTING

HANDLE = MI_HANDLE

EXCEPTIONS

OTHERS = 1. [/code]

please award points
