Stored procedure logic to update HANA custom table from calc view

Hi,

I need some help in creating stored procedure to update hana custom table. We need to persist output from calculation view.

PROCEDURE"_SYS_BIC"."TEST" ( )

       LANGUAGESQLSCRIPT

       SQLSECURITYINVOKER

    --DEFAULT SCHEMA <default_schema_name>

       READSSQLDATAAS

BEGIN

DELETE FROM "Schema"."HANA_CUSTOM_TABLE";

INSERT INTO "Schema"."HANA_CUSTOM_TABLE";

and then some syntax for inserting from calc view below...

SELECT

Field1,

Field2,

Field3

FROM

  "_SYS_BIC"."HANA calc view";

END;

Thanks
