One thing is the file name that u give doesn't make any sense to me. Becuse the files in the SAP application server are stored in unix OS. SO the file naming convention u have followed is incorrect. One more thing r u trying to download file to Presentation server???

hi,

you must transfer matab1 to file mfilename

with:

loop at matab1.
 transfer matab1 to mfilename.
endloop.

no where you given TRANSFER <DATA> TO FILENAME.

then how you can store data in the file..

<b>open dataset mfilename for INPUT IN TEXT MODE ENCODING DEFAULT.
if sy-subrc <> 0.
exit.
endif.
close dataset mfilename.</b>

here you are opening the file and then closing it.in between you should use TRANSFER to transfer itab data to the file.

Thanks for fast response.

I am trying to genarate file in presentation server ,but when it is foreground it is working fine,but in background it is not generating file.

[Former Member]

you can NOT directly download data to the presentation server in BACKGROUND mode.

here is the link how to do this,with this way you can download it to the presentation server.
