You correct the forecast results in the same way as you correct the historical values on which the forecast is based.
One method is to enter a new value in the Corrected forecast value column of the Forecast Results dialog box.
Alternatively, you can use the interactive graphics:
A business graphic and a statistics graphic appear. You can modify forecast values in the business graphic. The statistics graphic gives you an overview of the forecast and shows all the forecasted data. Thus, the statistics graphic provides a good basis for evaluating the quality of the forecast.
A dialog box appears showing the revised forecast results.
