01 / Required inputs

Load the assumptions your team can explain.

Required fields establish the row and its planning context. Optional fields add stockout, event, or commercial context when it is available for the row.

02 / Outputs

Keep the recommendation auditable.

The workbook makes its baseline, adjustments, totals, and exception logic visible. Every example below is illustrative, not a forecast-accuracy claim.

OutputFormula / assumptionExample
Baseline forecastAverage of the selected historical demand periods1,300 units
Consensus planBaseline forecast × (1 + event / planner adjustment)1,430 units
Override percentage(Consensus plan − baseline forecast) ÷ baseline forecast10%
Period-total demandSum of historical demand units in the selected review window7,800 units
Actual-vs-plan varianceActual demand units − consensus plan units+140 units
Exception statusReview when absolute variance crosses the workbook thresholdReview
Exception reasonShort explanation such as event, stockout, or demand above planDemand above plan after event
Review statusOpen, reviewed, or accepted by the planning ownerOpen

03 / ERP + WMS compatibility

Useful before the first planning review.

The workbook accepts exports from the systems your team already uses. It documents ownership and normalization without connecting to either system.

ERP owns the planning spine

Use ERP extracts for item master, sales or order history, customer/channel, lifecycle, and commercial-calendar inputs.

WMS adds availability context

Use WMS exports for availability, shipment or fulfillment, location, and stockout context when those fields improve the review.

Normalize before loading

Keep one extract key, one period grain, one unit of measure, and a snapshot timestamp across every source file.

Review the handoff offline

The workbook accepts exports and documents assumptions; it does not connect to an ERP or WMS or refresh live data.

Important: normalize the extract key, period grain, unit of measure, and snapshot timestamp before loading Inputs. This is an offline planning starting point, not a live ERP/WMS integration.
