When I view an invoice I can see if a discount was applied to each line item. However when I print the PDF for it I do not get the discount as a line item but just a total. I see my table headers in:
/app/code/core/Mage/Sales/Order/Pdf/Invoice.php
May I ask what my "feed" number is for discounts? Also is this the only file that I need to copy over to local to edit?
