Advanced scenario settings

Reuse a scenario

Open a scenario to review or rename it. Reuse configuration starts a new scenario with the same settings. It leaves out fields Forecast no longer supports and lists them for you to review.

Use JSON configuration when needed

For advanced setup, you can enter settings as text in JavaScript Object Notation (JSON). Load a scenario_parameters template with the fields Forecast accepts. Remove any fields marked as rejected before you submit. Fields marked as ignored won't be used, but they won't block submission. If the template can't load, you can still enter JSON. Forecast checks it when you submit.
