Need report in CSV format to run own scripts.

Hi,

I am trying to run a data set which gives us the top users for the day and we are getting the right output. Now need to schedule that report for every 24 hr and dump that in our linux server in "CSV" format. I found that there is schedule option and output profile option, though in the output profile I have selected the output as CSV while scheduling it is showing as 'Generate PDF' for every 24 Hour. It would be great if someone could guid me in the right way.
