Scenarios are like layers of small budget changes that can be combined with a base budget to quickly compare and explore multiple outcomes and projections. While you can add the scenarios as layers to your budgets in Reports and Dashboards, the preview mode explained in this help article allows you to view and explore different projections directly in the scenarios editor.
Browse to Budgets & Cashflow -> Scenarios
Select the required scenario, date ranges and business units as per the Budgets & Scenarios: Views & Layouts help article
Click PREVIEW MODE to toggle between Preview Mode and Edit Mode
While in the Preview Mode you can use the blue configuration bar to select a Base Budget to combine with scenarios for further analysis
Use the Add a scenario dropdown to add or remove additional scenarios to analyse the different outcomes
As you make changes the data will automatically refresh with the consolidated result of the base budget and selected scenarios
