SLT - Clarification

Hi  Gurus,

We are planning to implement SAP  HANA and pull data from ECC  to HANA via SLT.

Please clarify to me if the below points are right.

1. Via SLT we can replicate only the tables from ECC system. Can we replicate only transparent tables or can we replicate the cluster and pooled tables?

2. While we replicate the table can we  enhance them in SLT?

3. Can we use SLT to pull data from BW? Even in BW only the tables are possible, is that right?

Thanks.
