The forecast estimates the potential demand for the future. Demand Forecasting uses several calculation methods.
The app detects the best method for your data, but you can also select from the following forecast methods:
Forecast graph and table
The forecast is calculated individually for each record, and for each level.
The graph and table represents the following results of the calculation:
Historical data (Cleaned or raw, depending on your choice)
Top down/Bottom up forecast
The graph and table show data for the record selected in View side panel tab. The selected record is named in the header of the graph and table.
Action on the graph
Show previous forecast: presents the forecast result of the previous planning
Show base forecast: by default the user sees the proposed forecast value, so the chart adapts to changes made on proposed values. Using this function the user can present the original values too.
Show top down forecast: presents the record’s forecast value based on the disaggregation from the higher level (if exists)
Show bottom up forecast: presents the record’s forecast value based on the aggregation from the lower level (is exists)
You can edit the Proposed forecast by double-clicking a value in the table. Other data rows cannot be edited here.
Changes in a record’s data for a period are highlighted, and proposed forecast is recalculated on other levels by aggregation/disaggregation.
Action on the table
To compare the results of the forecast, the forecast for each level is calculated top down and/or bottom up. You have these options in the action menu in the top right corner of the table:
Mark as reviewed: the selected records is marked as reviewed
Set to base: the proposed forecast for the selected record is set to the base forecast
Set to top down: the proposed forecast for the selected record is set to the top down forecast, available on Low and Medium level
Set to bottom up: the proposed forecast for the selected record is set to the bottom up forecast, available on Medium and High level
Force down: the proposed forecast for the highest level is set to force down forecast
