Multiple fact tables

I have forecast and actuals information about budget. They would all share most of the dimensions and would have the same fact attributes. What are the benefits/ downsides of having a fact table for forecast, and another fact table for actuals vs. having one fact table and a dimension attribute that differentiates whether the fact record is a forecast or actual?
