Hello Friends,
If we want to load the data to SAP HANA as batch process like ETL then we have to use SAP Business Objects Data Services (BODS).
We can load the data from any source (ECC, BI, Flat File, etc) to HANA using BODS.
The major steps are
1) Create the connection to SAP ECC system
2) Import the metadata of tables from ECC to HANA system
3) Import the metadata back to BODS
4) Create the Project and job in BODS to load the data to HANA
5) Execute the job in Data Services
6) Preview the data in HANA
Look at the below document for step by step procedure
Data Provisioning using Data Services for SAP HANA
Hope it helps
Happy Learning
