Magento: столбец не найден: 1054 Неизвестный столбец 'e.display_price_group_0' после перестройки плоского каталога товаров

Question

В magento после программной перестройки плоского каталога товаров с помощью скрипта, который я нашел на http://www.magentocommerce.com/boards/viewthread/43238/, я получаю сообщение об ошибке exception 'Zend_Db_Statement_Exception' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'e.display_price_group_0' in 'field list'' всякий раз, когда пытаюсь обновить свойства продукта.

Еще большестранно, я проверял другие установки Magento и, кажется, в таблице нет столбца "display_price_group_0" catalog_product_flat_1 ...

У кого-нибудь есть подсказка относительно того, что происходит?Как правильно программно перестроить плоский каталог?Большое спасибо!
