In a display business rule, which value is not accessible?

• A. Previous
• B. Current
• C. Display
• D. New

Answer: (A)

Display rules run on the client as the form renders, so they can work with values that exist in the current form state: the value currently loaded from the server (Current), the value actually shown to the user (Display), and the value the user has typed in that hasn’t been saved yet (New). The previous value—what the field held before the current load or last save—is not available to a display rule, since that history isn’t part of the client-side form state. To access or compare the previous value, you’d need server-side logic such as a before/after rule or separate history tracking.
