Hi Abhi,
It could be many things, let's try and figure what the problem is.
Did you configure the underlying database as defined in the HANA EIM Administration Guide?
If so, can you have a look at the following logs to see if there are any errors and post some info about it?
dp agent - /usr/sap/dataprovagent/logs/framework.log
replication admin logs - /usr/sap/dataprovagent/LogReader/admin_logs/adminxyz.log
replication instance log - /usr/sap/dataprovagent/LogReader/<instance_name>/log/<instance_name>.log
Best Regards,
Richard
