Demand
A forecast that becomes the plan the MRP run reads
The usual break is the very first step: a forecast built somewhere, pasted somewhere else, and nobody able to say which numbers are the forecast and which a planner changed. In Cairn a forecast run is approved into its demand plan, and the active plans and your firm orders are what the MRP run reads.

How Cairn closes the gap
The legacy gap
Forecasts live in a spreadsheet, firm orders live in the ERP, and the plan double counts the overlap. A retailer's order for 600 cases on top of a forecast of 2,000 reads as demand for 2,600, and the buyer buys for it.
What Cairn does
Cairn approves a statistical or uploaded forecast run into its demand plan, where planners edit lines and each line keeps its source. Firm orders consume their own bucket first, then reach backward and forward through a window ladder you set per item and site. Inside the demand time fence the forecast is set aside and only firm orders drive supply.
The payoff
The number in the plan has a source you can point to, firm orders are never counted twice, and the planning run, the overlay and the time-phased view all read the same consumption pass.
What it does
Forecast run into a plan
A statistical or uploaded run is approved into its demand plan. If a plan already exists for the same scope, Cairn asks before it overwrites anything.
Lines a planner can own
Planners edit plan lines and each line keeps its provenance, so a hand edit is never mistaken for the forecast.
Consumption with a window ladder
Each firm order consumes its own bucket, then the nearest neighbours backward and forward, within the window set for the item and site.
A demand time fence
Inside the demand time fence the forecast is set aside and only firm orders drive supply, so a stale forecast cannot plan stock that close in.
