I have read in the release notes for 7.0.2 that I can now alter the line_items.js in an upgrade safe way. This is very interesting to me. Unfortunately I could not find any documentation except for an old post (http://www.salesagility.com/index.php/forum/8-aos-5x/2829-service-quantity-on-aos-5-3-1#4198) in the AOS forum. So I guess, 7.0.2 brings the upgrade safe feature Will speaks of.
Could you provide any more info on how to change this?
So I just put a file with the name “line_items.js” in /custom/modules/AOS_Products_Quotes/ that contains the functions I want to use instead of the default ones?
