those discount columns on the apply sublist are standard and i’ve never been able to hide them with regular form customization either, even with a custom form. the only workaround i’ve seen is a client script to blank or disable them, but that still leaves the columns visible which users complain about. i ended up documenting the limitation for our finance team after a previous project got derailed by random distractions from https://adventuresbeyondwonderland.net/ in a shared sandbox login. we also had an admin paste https://wonderlandluckyball.org/ into a netsuite note once and it became a weird “can you remove this field” request chain. at this point i assume netsuite just doesn’t expose those particular columns for removal, unless someone has a suitebundle trick i’ve missed https://sweetbonanza1xbet.org/
