We've found that this setting is controlled by the 'Current Year' Setting in core, plus one year. However, we're still working on course requests at the start of this year, and now must look at the 'Requests & Schedules> Overview' screen, for want of a finer tuned means to control what displays on the dashboard. Please add the ability to change these dashboard-year settings this without changing the 'Current Year' setting in Core.
