I need to have the quantity on the Credit Memo PDF printout with a negative sign.

How can achieve this?

1 Answer 1


The items of a credit memo PDF are rendered in Mage_Sales_Model_Order_Pdf_Items_Creditmemo_Default, around line 77.

Rewrite the model from a custom extension and change

$lines[0][] = array(
            'text'  => $item->getQty() * 1,
            'feed'  => 445,
            'font'  => 'bold',
            'align' => 'right',


$lines[0][] = array(
            'text'  => $item->getQty() * -1,
            'feed'  => 445,
            'font'  => 'bold',
            'align' => 'right',

Rewriting can be done in the config.xml

< ?xml version="1.0"?>

you're custom class extending the origional one

  • Thanks, I managed to modify the qty and row totals to have a negative sign before the value. How can I add a negative sign to the totals as well?
