Replication required for Business suite on HANA

Hi Experts

We are trying to understand the 3 ways to Implement HANA

1)SAP HANA as a Data Wareshouse for Analytics

2)SAP BW on SAP HANA

3)SAP Business suite on SAP HANA

My question is -> for Option 3 do we need to replicate data for BO reporting ? or we can just directly create Views on SAP HANA tables of ECC.

Thanks..
