Hello Sunil,
in which schema you wanna create your table?
You are allowed to create tables e.g. in your NEO_<guid> schema. You can determine the name of your schema by a select on view "HCP"."HCP_DEV_METADATA".
For more information please have a look to SAP HANA Cloud Platform - Specific Procedures and Views for Trial Instance.
Best Regards,
Florian
