I’m trying to change field label of the Discount field when entering and viewing line items on product quotes (see highlighted text in linked images). I couldn’t find the right field so I searched every en_us.lang.php file and changed anywere I found the label Discount. It still didn’t change these two fields. I tried changing the language file for the following modules: AOS_Quotes, AOS_Product_Quotes, AOS_Contracts, AOS_Invoices, AOS_Line_Item_Groups, Spots
How do I change these two labels?
