Write File on SFTP Server from SAP

SAP ABAP has the Functionality to write/Read on FTP server,but there is no functionality in ABAP  to read /Write on SFTP server.You only have the option of XI/PI to Write/Read on SFTP location.

I Googled and managed to Read/Write on SFTP server from SAP Application Server with the help of an open Source FTP client.

Below are the Steps to write on SFTP location

Assumptions

Operting System : Windows

Database : Oracle

SAP Version : Netweaver 7.0 ECC 6.0

Step 1

Download and install WinSCP.You can download WINSCP from  http://winscp.net/eng/download.php 

Step 2

Check the connectivity from SAP Server to SFTP server with WinSCP

Create the WinSCP Login and maintain the connection string

maintain the logon details and Save

you can either check the connectivity with GUI or with Command Prompt

Command to check connectivity is : open sftp://<User>:<Password>@<SFTP_Server> -hostkey=”ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx”

after checking the connectivity create a batch script of WinSCP commands.you can find the list of available commands of winscp from http://winscp.net/eng/docs/scripting

a Sample script will give you an idea how it looks like

Open NotePad and write the content and Save it witj .txt extension.

# Automatically abort script on errors

option batch abort

# Disable overwrite confirmations that conflict with the previous

option confirm off

# Connect using a password

# open sftp://user:password@example.compassword@example.com -hostkey=”ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx”

# Connect

open sftp://user@example.com//user@example.com -hostkey=“ssh-rsa 1024 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx”

# Change remote directory

cd /home/user

# Force binary mode transfer

option transfer binary

# Download file to the local directory d:\

get examplefile.txt d:\

# Disconnect

close

# Connect as a different user

open sftp://user2@example.com//user2@example.com

# Change the remote directory

cd /home/user2

# Upload the file to current working directory

put d:\examplefile.txt

# Disconnect

close

# Exit WinSCP

exit

Step 3

Create command in SM69

Go to transaction SM69 and create external operating system command.make sure to tick additional parameters and trace

you can test the command by executing it.

Step 4

Call the newly created external Command using FM : SXPG_COMMAND_EXECUTE

you can then write the program and call the external command which will execute and Write/Read the File on SFTP server.
