Accessing Oracle Views using Phalcon

In a Phalcon project, I have multiple database in Oracle and mySQL with number of tables and views. Created models for corresponding tables and views. But unable to access views. I initialize in model below:

public function initialize()

{
    $this->setConnectionService('dbBznes');
    $this->setSchema('POLICY');
    $this->setSource("BUSINESS_ALL"); 
    // view name
}
Return error message : 
Table 'POLICY'.'BUSINESS_ALL' doesn't exist in database

if I use $this->setSource("table1"); is working fine but $this->setSource("view1"); showing error.
