Can anyone please help me out on this?. Thank You

Try to replace in the file magento\app\code\core\Mage\SalesRule\sql\salesrule_setup\install-1.6.0.0.fp
lines 333-335:

-> addColumn (’period’, Varien_Db_Ddl_Table :: TYPE_DATE, null, array (
‘nullable’ => false,
), ‘Period’)

on

-> addColumn (’period’, Varien_Db_Ddl_Table :: TYPE_DATE, null, array (
‘nullable’ => true,
), ‘Period’)
