Trigger UNIX Script from SAP

Former Member — Fri, 28 Oct 2005 05:37:05 GMT

Hi..

The requirement is as follows :

SAP drops a file into a folder and triggers a UNIX script using a File Port partner destination.

Unix script will perform a secure copy to the Webmethods server. If a Unix script error occurs, an Rfc function will be called to send an error notification to a particular contact person.

Can anyone help me how is the unix script triggered from SAP ?

Thanks in advance

Hi Sumi,

You should create an external OS command (transaction SM59) which starts the script. You can then execute this command from within you ABAP program using FM SXPG_COMMAND_EXECUTE.

John.

You can execute this sample code:

Data: unix_cmd(50).

unix_cmd = 'chmod 664 /sapdata/DEV/home/travelers'.

translate unix_cmd to lower case.

call 'SYSTEM' id 'COMMAND' field unix_cmd.

write: / sy-subrc.

Hi Sumi,

You can also go through this PDF file.

Hey now, if you're gonna link to my site (guidancetech.com), I should at least get some of the SDN points!

Most of those sample programs were things I found on the 'net back in the mid 1990's so are probably very outdated, although they may still work. Use them at your own risk...

One of these days I need to clean those pages up.
