Hi Gaurav,
1. Create ODP Source in BW system (ODP-SAP HANA Information Views (HANA))
Notes about Transferring Data from SAP HANA Using ODP - Modeling - SAP Library
2. Using this ODP BW Data Source,
Create Open ODS View in BW on top of ECC HANA Live Models.
3. Using Composite Provider, you can combine BW object (DSO) and Open ODS View.
Regards,
Muthuram
