Re: RMSE and MAPE calculation

When you do a forecast in EViews, one of the options on the forecast dialog is for "forecast evaluation". By default that option is selected. When it is selected, the forecast will show a table with forecast evaluation statistics in it, including RMSE and MAPE.

Note that, obviously, if the dependent variable doesn't have actual data for your forecast sample, forecast evaluation is impossible, and EViews will not show it.

Re-do the forecast in the same way you did before. It is still valid.
