            'db' => Yii::$app->db2, // set other database connection rather than default
			'attribute' => 'sales_num', // required
			'group' => $this->id_branch, // optional
			'value' => 'SA.'.date('Y-m-d').'.?' , // format auto number. '?' will be replaced with generated number or you can use " 'value' => function($event){ return 'SA.'.date('Y-m-d').'.?' } " as long the return value contain '?' character
			'digit' => 4 // optional, default to null. 
		],
	];
}

// it will set value $model->sales_num as 'SA.2014-06-25.0001'

Instead of behavior, you can use this extension as validator

public function rules()
{
    return [
        [['sales_num'], 'autonumber', 'format'=>'SA.'.date('Y-m-d').'.?'],
        ...
    ];
