Exporting HANA table to flat file using Data Services 4.1 only

Very Urgent    

I need to export a HANA table to a flat file using data services only since the job needs to be scheduled. I also need to add two empty columns to the file. I searched but found videos to load from flat file to HANA and not the other way around.

Please write in detail how to do it. Really appreciated.

Thanks in advance
