Did you use the Organic Internet extension which is the SimpleCOnfigurableProducts? If so, the simplest fix will be to make changes on this file app/code/community/OrganicInternet/SimpleConfigurableProducts/Catalog/Model/Resource/Eav/Mysql4/Product/Indexer/Price/Configurable.php
From:
$select->columns(array(
'entity_id' => new Zend_Db_Expr('e.entity_id'),
'customer_group_id' => new Zend_Db_Expr('pi.customer_group_id'),
'website_id' => new Zend_Db_Expr('cw.website_id'),
'tax_class_id' => new Zend_Db_Expr('pi.tax_class_id'),
'orig_price' => new Zend_Db_Expr('pi.price'),
'price' => new Zend_Db_Expr('pi.final_price'),
'min_price' => new Zend_Db_Expr('pi.final_price'),
'max_price' => new Zend_Db_Expr('pi.final_price'),
'tier_price' => new Zend_Db_Expr('pi.tier_price'),
'base_tier' => new Zend_Db_Expr('pi.tier_price')
));
To:
$select->columns(array(
'entity_id' => new Zend_Db_Expr('e.entity_id'),
'customer_group_id' => new Zend_Db_Expr('pi.customer_group_id'),
'website_id' => new Zend_Db_Expr('cw.website_id'),
'tax_class_id' => new Zend_Db_Expr('pi.tax_class_id'),
'orig_price' => new Zend_Db_Expr('pi.price'),
'price' => new Zend_Db_Expr('pi.final_price'),
'min_price' => new Zend_Db_Expr('pi.final_price'),
'max_price' => new Zend_Db_Expr('pi.final_price'),
'tier_price' => new Zend_Db_Expr('pi.tier_price'),
'base_tier' => new Zend_Db_Expr('pi.tier_price'),
'group_price' => new Zend_Db_Expr('pi.group_price'),
'base_group_price' => new Zend_Db_Expr('pi.group_price')
));
And...
From:
$outerSelect->columns(array(
'customer_group_id',
'website_id',
'tax_class_id',
'orig_price',
'price',
'min_price',
'max_price' => new Zend_Db_Expr('MAX(inner.max_price)'),
'tier_price',
'base_tier',
#'child_entity_id'
));
To:
$outerSelect->columns(array(
'customer_group_id',
'website_id',
'tax_class_id',
'orig_price',
'price',
'min_price',
'max_price' => new Zend_Db_Expr('MAX(inner.max_price)'),
'tier_price',
'base_tier',
'group_price',
'base_group_price'
#'child_entity_id'
));
Hope that helps...
