Hi Amol,
if you would like to access HANA as a secondary database you have to maintain an entry in the connection table, otherwise you will not be able to access it at all (see http://help.sap.com/abapdocu_70/de/ABENOPENSQL_MULTICONNECT.htm). This document talks about secondary database connections via Open SQL, but the same thing holds true for nativ SQL.
How else would you communicate with the HANA DB?
Best,
Jasmin
