Write to file from report runing in background job-problem

Hi everybody

i'm having a problem when writing data from internal table to a txt file on the application server and the abap report is running in background.

At first i thought the function module 'SAP_CONVERT_TO_TEX_FORMAT' that converts an internal table to text, was causing problems so i commented it out and wrote my own code for transformation of internal table to text, but i'm still having the same problem - sometimes the data is written to file on the application server and sometimes not (even the file is not created, although open dataset and close dataset commands perform with no errors).

I looked in the help pages if maybe TRANSFER command requires any parameters for background execution, but i did not find anything.

Any suggestions?

And the code:

//**************************************************/

OPEN DATASET fname FOR APPENDING IN TEXT MODE ENCODING UTF-8.

case sy-subrc.

when 0.

write: /'File ', fname, 'successfully opened!'.

when 8.

write: /'Could not open file ', fname.

exit.
