I am wanting to modify via script the amount of a line item on a transaction which without changing the price level to custom, generates an alert that the amount does not match the quantity times rate. I know it doesn't match since I am doing it via script so I don't want the alert to pop up in the face of the user -- very unintuitive and confusing to them!

Since Netsuite does not support duration based transactions (qty X duration X duration rate), I need to change amount to equal the rate times the duration (custom column) times the quantity and this of course makes the amount not equal to qty times rate, thus up pops the annoying alert.
