As I'm with SAP, my answer to that is:
Go get DataServices. It manages such things (and lots more) extremely well. It's flexible about the data format, it's great to automate and monitor.
Or you go low tech.
Make the files available to the SAP HANA server, write a SQL command to import the data via IMPORT and schedule the file execution via CRON.
There's a whole plethora of options in between, so again: the choice is yours.
