Hi DineshChakkravarthi,
You would need packageprivilege on shine Package (sap.hana.epm), object privilege on schema (sap_hana_epm) and application privilege (sap.hana.democontent.epm.admin).
You would also need UIS privileges to view UIS content as Role SITE_USER and application Privilege AppsiteAccessAll.
Regards,
Anjali.
