Loop through each Product (Quote line items) in SugarCRM and save it. You can use something like this to update SugarLogic/Calculated fields for a module.

save-all-products.php

<?php

$sql = "SELECT id FROM products WHERE deleted=0"; 
$result = $GLOBALS["db"]->query($sql);
while ($product = $GLOBALS["db"]->fetchByAssoc($result))
{
     $product = BeanFactory::getBean("Products",$product["id"]);
     $product->save();
}
