Data replication in HANA database

Hi Gurus,

I need your sugessions in solutioning (I am new to HANA).

Environment:

ECC6 EHP6

HANA Ver. 1.00.74

SLT Ver. DMIS 2011 SP5

BOBJ 4.1 SP4

Client has HANA installed as a stand alone database means (ECC is not on HANA and they dont have BW)

I need to replicate ECC data in HANA and create models to support reporting.

Question1: What is the best approach to replicate data in HANA (SLT, DS etc?)

Question2: Another requirement is write data back to HANA database. Users would like to enter new data (numeric data/key figure/measure) from a report to HANA. How can we achive this?

Thanks.
