Hi Harish,
right now, there are following options:
- Use HCI Data Services: SAP HANA Cloud Integration for data services – SAP Help Portal Page
- Smart Data Integration (SDI): http://help.sap.com/hana_options_eim/
and https://www.youtube.com/watch?list=PLkzo92owKnVwQ_preA3cxlQjn_v3W0Eh5&v=EfUlJAKMBak
SDI is currently not yet productively useable on HCP, but you can already start using it for your PoC.
Best regards, Timo
