The automatic forecast is based on the historical sales and is recomputed by Inventory Planner every day. Sometimes it makes sense to manually override the automatic forecast to more closely align it with your plans. It can be especially useful in the following situations:
- You are planning a marketing campaign or other changes to your business and projections based only on past sales are not reliable enough.
- You are planning purchases and would like to review the forecast first and fix it. Once the forecast has been fixed for a period, it stops recomputing every day. This allows you to postpone creation of purchase orders
- You are receiving new products and would like to manually enter the initial demand for them.
To override the forecast, check actual sales and edit the forecast override accordingly.
Entering the forecast override updates the planned sales (used for replenishment recommendations). If the difference between the automatic forecast and the forecast override it more than 30% it's highlighted in red.
You can also specify the forecast percentage increase which is applied for the forecast override (if set) or for the automated forecast. The final result is shown in planned sales.
To make changes in bulk, select some products using checkboxes on the left and use the Bulk Actions menu. It allows to apply same action to a group of products:
- recompute the automatic forecast
- clear the forecast override
- add/remove the percentage increase
- enable/disable the seasonality
Top-Down tabs allow to check and review the aggregated forecast for categories, vendors and the entire store. This forecast can be overwritten and reconciled with variants. Scale Down button updates the forecast override for variants from the aggregated forecast using automatic forecast distribution. Scroll right to see the Scale Down button.
For example you have two products in a category. The automatic forecast for these products is 10 and 20 units for December. The bottom-up forecast for the category is 30 units (10 + 20). When you override the top-level forecast to 60 (+100%) and scale it down to variants it makes it 20 and 40 correspondently.
