I would like to add a field to the multi line opportunity products page. This field must display data that exists on the product's page. I understand that you can't add a formula field to the multi line layout. How do I get my data (from the product) to display on the multi line page layout.
Whats an example of the data that you are looking to add. Also, for clarity, are you talking about the page where you enter values for quantity, price, etc when adding products to an Opp?
