What is the year menu at the top of the Data Sheet?

Each budget scenario may contain multiple years of data. For instance you might budget out 3 years into the future, or you might copy previous years' actual data into a budget so your users have a reference point as they build that budget.

The year menu at the top of the Data Sheet allows you to switch between these different years.

You will see this option elsewhere too, at the top of your formula pages, and the employee module.
