If you don't have e-prescribe turned on you can't do this function. You can however (uck) remove the allergies that are in the allergy column until you get down to the NKDA, unselect that and then you'd have to re-add the correct allergies back in. We were having problems with the migration of the allergy from V4 was free-text and that's taken a bit to sort out how to fix.
