hi,
<b>reward if useful</b>
<b>GUI_* and WS_* function modules do not work in background</b>
When scheduling a job in the background the appropriate statement to read in your file is OPEN DATASET, and the file must be on the file system that the SAP server can see.
At anytime, a user can switch of the Personal Computers even though the job is still running in the background.  Therefore GUI_* and WS_* function modules are not designed to work in that way, as they need to access your personal computer  file.
Download in Background in Excel Format
How to download the data in excel format directly while executing in background mode? 
If you will execute it in bacground with ws_download or download, it will be aoutomatically cancel. so what is the procedure to do this.  How is can directly read the spool from program?
<b>Download from background is possible, if you could setup the environment</b>
1. create a custom table first
    Table  : Y001
    Displayed fields:   4 of   4  Fixed columns:
       MANDT BNAME       Y_SITE    Y_PATH
       010      <userid>     <site>      cd <novell_path>
2. rewrite ws_download to z_download (light modification required, see attachment)
3. ask your basis team to make a copy of command FTP and CHMOD to ZFTP and ZCHMOD resp., make the setting according to your environment.
