Hello Megha,
I assume, from what I have seen out of your recent posts, that you are using the shared HANA trial instance.
On the shared HANA trial instance you do not have privileges or can assign privileges for the mentioned procedure to your user. Instead of that there are special grant procedures in schema HCP (all are starting with HCP_GRANT_*). For instance you can call "HCP"."HCP_GRANT_SELECT_ON_ACTIVATED_OBJECTS" to grant select privileges for the activated objects to your user.
By the way, you should switch to the MDC HANA trial instance (SAP HANA Multitenant Database Containers (MDC) scenarios now on trial landscape), because the shared instance will be shut down on 1st July as announced in the latest release notes (Release Notes for SAP HANA Cloud Platform)
Regards,
Florian
