I added attributes in this way without problems:

 $this->startSetup(); $installer = new Mage_Sales_Model_Resource_Setup('core_setup'); $entities = array( 'quote_item', ); $options = array( 'type' => Varien_Db_Ddl_Table::TYPE_DECIMAL, 'visible' => true, 'required' => false ); foreach ($entities as $entity) { $installer->addAttribute($entity, 'packing', $options); } $installer->endSetup(); $this->endSetup();

But when I try to remove the attributes it gives me error: WRONG Entity ID:

 $this->startSetup(); $installer = new Mage_Sales_Model_Resource_Setup('core_setup'); $entities = array( 'quote_item', ); foreach ($entities as $entity) { $installer->removeAttribute($entity, 'packing'); } $installer->endSetup(); $this->endSetup();

$setup = new Mage_Eav_Model_Entity_Setup('core_setup'); $attribute = 'packing'; $setup->removeAttribute('quote_item', $attribute); $setup->endSetup();
