In my current architecture, I have data in SAP R3 system as well as in Oracle database. On top of SAP R3 I have SAP BI above which I have SAP BO for reports development.
I such an architecture, I wanted to know, if I want to implement HANA, where in the flow will HANA come into picture? On implementing HANA, I will not need Oracle as a database? I mean, HANA will work as a database?
Also, should I implement BODS? Where will BODS come into the flow?
