Objective

Mark unusual historical periods so they do not distort the data used for forecasting.

Environment

  • You have permission to manage Forecasting Settings.
  • You know when the unusual event occurred and can describe why that period should be excluded.

Resolution

  1. Open Forecasting Settings → Outliers. Review existing exceptions, including any detected from uploaded data, before adding another for the same period.
    Review existing outliers, their date and time windows, reasons, and active states.
  2. Select Add Outlier. Enter a Name, Start Date, End Date, and Reason. Add Notes if the event needs more explanation.
    The outlier form captures the affected dates, optional times, a reason, and explanatory notes.
  3. Set Start Time and End Time when only part of a day should be excluded. Leave both times blank to exclude full days, then save.
    Note: The time range is continuous

    Entering times creates one continuous window from the start date through the end date. Check the full range before saving.

  4. Confirm the outlier appears in the list with the correct period and active state. Edit or deactivate an incorrect entry before the next forecast.
