Creating table (Entity) using CDS in _SYS_BIC

Hello Experts,

I have been trying to create tables using DDL files ( .hdbdd ) in schema _SYS_BIC.I have writen the code , syntax checked..and activated.But I am not able to see those tables, neither I am able to see the schea _SYS_BIC in the catalogue.

Could you please tell me what I need to do extra to get those tables created ?

FYI..I am using the free HCP trial account provided by SAP and I am really new in HANA developments.

Code :

@Schema: '_SYS_BIC'

context Books {

type ISBN: String(15);

type amountType {

amount: Decimal(5,2);

currencycode: String(3);

};

entity books {

key isbnNumber:ISBN;

title: String(50);

published: Integer;

pages: Integer;

price: amountType;

};

entity authors {

key id: Integer;

firstname: String(10);

lastname: String(10);

};

entity bookauth {

key isbnNumber:ISBN;

key author: association to authors;

};

};

Thanks,

Supy
