FTP

[Former Member]

Hi all,

We do have couple of interfaces where SAP needs to put their files into FTP server so that XI can pick it up and vice versa.

As of now the files are been put into Application server of SAP and sent manually via email.

Let me know the possible ways for the same.

Your help is most appreciated!

If you are trying to write files from SAP using ABAP to an FTP server for XI to process, you are missing the point to XI.

You should be sending the data to XI via an ABAP proxy.

Hi,

Sorry, it is already too late. As SAP is not sending via RFC, IDOC or Proxy, do let me know for any other alternative.

[Sm1tje]

So what exactly is your question? An alternative to email, or how to do FTP in SAP?

1. For FTP have a look at all the sample programs etc. in package SFTP.

2. Alternative would be to connect to XI via RFC for sending files. Create a generic FM which can handle all transfers (table of type STRING for example).

Hi,

one Possiblilty is create a staging directory in the XI server then FTP the files to that server using the 2methods,

1- using this program to FTp files outside of SAP

DATA: hdl                  TYPE i,
        compress             TYPE c VALUE 'N',
        ftp_command(200)     TYPE c,
        dest                 LIKE rfcdes-rfcdest VALUE 'SAPFTPA'.

  data : key type i value 26101957,
         dstlen type i .

  TRANSLATE command TO LOWER CASE.
  TRANSLATE transfer_type TO LOWER CASE.
  TRANSLATE verify TO UPPER CASE.

  CASE command.
    WHEN 'put'.
    WHEN 'get'.
    WHEN 'append'.
    WHEN OTHERS.
      RAISE command_error.
  ENDCASE.

  CASE transfer_type.
    WHEN 'ascii'.
    WHEN 'binary'.
    WHEN 'ebcdic'.
    WHEN 'image'.
    WHEN 'local m'.
    WHEN 'tenex'.
    WHEN ' '.
      transfer_type = 'ascii'.
    WHEN OTHERS.
      RAISE type_error.
  ENDCASE.

  CASE verify.
    WHEN 'Y' OR 'YES' OR ' '.
      verify = 'X'.
    WHEN OTHERS.
      verify = ' '.
  ENDCASE.

  IF sourcefile = ' ' AND command = 'put'.
    RAISE file_error.
  ENDIF.

  IF sourcefile = ' ' AND command = 'append'.
    RAISE file_error.
  ENDIF.

  IF targetfile = ' ' AND command = 'get'.
    RAISE file_error.
  ENDIF.

  CONCATENATE command sourcefile targetfile
    INTO ftp_command
    SEPARATED BY space.

2- Oresle use a UNIX script for transfering the file to that XI server.

Hi,

What do u mean by staging directory in XI? Can you be more specific on this.

[former_member226999]

XI can do the file transfer for you. The main idea of having XI is to act as a mediator for transfering informations across different landscape or systems. Send your data to XI and then it can put it across to the desired destination. Ask your XI consultant for more information.

Hi,

The below program is to create file on FTP server by taking the data from internal table.

To see whether the file is created on the FTP server

use the function module FTP_SERVER_TO_R3.

Check the below code.

You write a same program with the function module FTP_SERVER_TO_R3 instead of

FTP_R3_TO_SERVER to check the existence of the file which is already created.

hi,

I am sure i could help you ,i ve the scripts to do the FTP and i could give you by tommorrow as i dont ve all those scripts in my system now , for tha u need to know the receiving system ip address.

Thanks

Hi ,

I think the best way is passing your data to XI using ABAP PROXY and than let the XI do the rest. However the optimized method which you're trying to find out is also up to your file format.
