Error during HANA plugin installation

Dear Experts,

We're trying to install GRC 10.1 HANA Plug-in in Our Hana DB via HANA Studio.

We're facing error "The schema name "SAP_PI_GRC" must be equal to the object name "sappigrc"; delete this object and create a new one that matches the schema name; do not change the schema name in this object". See attached screenshot "HANA plugin install error"

According to SAP note: 2162881 - Message The schema name "SAP_PI_GRC" must be equal to the object name "sappigrc", as a workaround, i also tried to create schema "SAP_PI_GRC" via HANA studio but i am getting error "SAP DBTech JDBC: [386]: cannot use duplicate schema name: SAP_PI_GRC".

I don't understand, why it says, "cannot use duplicate schema name"? Currently, in my HANA modeler of HANA Studio, I don't have any original schema available with the same name "SAP_PI_GRC".

Any ideas, please?

Thanks & best regards,

Sreenu
