If you are new to forecasting, perhaps the easiest way to get started is to use a point-and-click interface which will guide you through the analysis, modeling and forecasting.

This page has general information about SAS studio.
This page has documentation regarding SAS Studio and the forecasting tasks.

I hope this information helps to get you started.
