How to generate a white noise model in EViews

Hi all,

I have a white noise model & need to find the Mean Absolute Error & Root Mean Squared Error, but I just dont know how to find it in EViews. Generally for MA or AR models I would generate the equation & then forecast ie y ar(1) or y ma(1), but how do I enter a white noise equation in EViews? My model is Yt=et - any help/direction would be greatly appreciated.
