Help , if there exists a Function Module

Hello everybody,

I want a help whether SAP has some Function Module which can take an "Internal Table" as an Import Parameter and give us "CSV File" as an export parameter , more-or-less like the "GUI_DOWNLOAD" Function Module , which downloads the file as ".DAT" or ".ASC" .

Please remember that i would need a CSV file , which i can read later through Opening a Dataset and transferring the contents into a file.

Your immediate answers is most needed.

Thanks,
