Hi,

We can first send the contents of internal table which you want to do FTP into an application server.

Then take this file as source and do ftp to the destination location.

for ex: you want to do ftp to www.abc.com and the destination folder is /xyz. and you have downloaded the internal table contents to application server path

say /app/filename. Then the code looks calling your own function module..

FTP the file

CALL FUNCTION 'Z_FTP_FILE'

EXPORTING

MACHINE_NAME = 'www.abc.com'

SOURCE_FILE = '/app/filename'

COMMAND_FILE = '/app/filename'

DEST_FILE = '/xyz/destfilename'

FTP_COMMAND = 'put'

TABLES

FTP_MESSAGE = L_FTP_MESSAGE

EXCEPTIONS

SOURCE_FILE_NOT_PROVIDED = 1

DEST_FILE_NOT_PROVIDED = 2

MACHINE_NAME_NOT_PROVIDED = 3

OTHERS = 4.

IF SY-SUBRC <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ELSE.

MESSAGE I000 WITH 'FTP is Successful'.

endif.

The code in this Z_FTP_FILE looks like :

FUNCTION Z_FTP_FILE.

*"----

""Local interface:

*" IMPORTING

*" VALUE(MACHINE_NAME) LIKE RLGRAP-FILENAME

*" VALUE(SOURCE_FILE) LIKE RLGRAP-FILENAME OPTIONAL

*" VALUE(DEST_FILE) LIKE RLGRAP-FILENAME OPTIONAL

*" VALUE(FTP_COMMAND) LIKE TOP_SINGLE-COMMAND

*" VALUE(COMMAND_FILE) LIKE RLGRAP-FILENAME OPTIONAL

*" VALUE(TRANSFER_MODE) OPTIONAL

*" TABLES

*" FTP_MESSAGE

*" EXCEPTIONS

*" SOURCE_FILE_NOT_PROVIDED

*" DEST_FILE_NOT_PROVIDED

*" MACHINE_NAME_NOT_PROVIDED

*"----

IF MACHINE_NAME = ''.

RAISE MACHINE_NAME_NOT_PROVIDED.

ENDIF.

Check to make sure all the parms that are needed are provided

TRANSLATE FTP_COMMAND TO LOWER CASE.

IF FTP_COMMAND = 'put' OR

FTP_COMMAND = 'get'.

IF SOURCE_FILE = ''.

RAISE SOURCE_FILE_NOT_PROVIDED.

ENDIF.
