hm… actually, @blue, let me correct myself. you CAN revalue asset up. See Suite Answers 24814

That's good to know thanks @Karina :) were you able to test and confirm it? Having some errors with my demo account atm related to accounting periods so I can't confirm it..

yes, @blue, it works 🙂 you add you r % in % box, click on “calculate”, than add “-” to the Amount box showing the amount - that will make the asset value to go up

Nice :) thanks @Karina! This should be in the official FAM document.
