Magento 1.9 – Fix Custom Attribute Not Appearing in Flat Product Table

Basically I installed one market place module in my website……that have a validation attribute…but which is not …Product Listing,Product Listing,Layered Navigation…so when I use Flat Product …its attributes and its value is not going in flat product tables…so due to not availability of attribute I can not validate my setting….

My attributes setting values..
----------------------------

class VES_VendorsProduct_Model_Source_Approval extends Mage_Eav_Model_Entity_Attribute_Source_Abstract
{
    const STATUS_NOT_SUBMITED   = 0;
    const STATUS_PENDING        = 1;
    const STATUS_APPROVED       = 2;
    const STATUS_UNAPPROVED     = 3;

    static public function getOptionArray()
    {
        return array(
            self::STATUS_NOT_SUBMITED   => Mage::helper('vendors')->__('Not Submited'),
            self::STATUS_PENDING        => Mage::helper('vendors')->__('Pending'),
            self::STATUS_APPROVED       => Mage::helper('vendors')->__('Approved'),
            self::STATUS_UNAPPROVED     => Mage::helper('vendors')->__('Not Approved')
        );
    }

    public function getAllOptions()
    {
        return array(
            array(
                'label' => Mage::helper('vendors')->__('Not Submited'),
                'value' =>  self::STATUS_NOT_SUBMITED
            ),
            array(
                'label' => Mage::helper('vendors')->__('Pending'),
                'value' =>  self::STATUS_PENDING
            ),
            array(
                'label' => Mage::helper('vendors')->__('Approved'),
                'value' =>  self::STATUS_APPROVED
            ),
            array(
                'label' => Mage::helper('vendors')->__('Not Approved'),
                'value' =>  self::STATUS_UNAPPROVED
            ),
        );
    }
}


My validation In List.php block
---------------------------------
$collection->addAttributeToFilter('approval',VES_VendorsProduct_Model_Source_Approval::STATUS_APPROVED);
