#update!(target = nil) ⇒ Object

Recalculate amount given a target e.g. Order, Shipment, LineItem

Passing a target here would always be recommended as it would avoid hitting the database again and would ensure you’re compute values over the specific object amount passed here.

Noop if the adjustment is locked.

If the adjustment has no source, do not attempt to re-calculate the amount. Chances are likely that this was a manually created adjustment in the admin backend.
