Calibration
Calibration in a manufacturing inventory or SupplyGrid context is the controlled process of verifying and, when needed, adjusting a measurement device, test instrument, or counting method against a known reference so recorded values match actual conditions within an acceptable tolerance. In inventory and material tracking, calibration applies to scales, gauges, scanners, and test instruments that affect count accuracy, lot acceptance, or process measurement.
On a real shop floor, calibration is a data-quality gate. A warehouse scale that drifts by a few grams can turn an accurate carton-weight check into a false freight charge or a wrong quantity-by-weight conversion, and that bad number flows straight into ERP and WMS inventory records. In production, a calibrated gauge determines whether raw material, work-in-process, or finished goods pass quality checks and stay eligible for inventory movement or shipment. Dynamics 365 models this as a formal workflow: an operator opens a due calibration, starts it, records test results, completes the record, and an approver signs off so the asset carries the approval date and next calibration date. That traceability lets the operation know which instrument was used, whether it is overdue, and exactly when it must be recalibrated, which protects downstream inventory accuracy and raw-material traceability across every receiving, put-away, and replenishment transaction.
What makes calibration different from inventory reconciliation?
Calibration validates a measurement device against a known reference to prove its readings are accurate. Inventory reconciliation compares physical stock to system quantity and posts variances in the ERP. Reconciliation only fixes the stock balance; it does not verify the instrument, so the same measurement error can continue causing future variances.
Why does calibration affect raw material tracking?
A drifting instrument can misstate received quantity, consumed quantity, or released quantity, which changes lot-level traceability and inventory valuation downstream. If a receiving scale is out of tolerance, every lot received through it carries incorrect quantities in the ERP and WMS, making traceability unreliable for both quality and financial records.
What system fields matter most in calibration control?
The central fields are due date, started by and start date, completed by and completion date, approval status, test result, and next calibration date. These fields provide traceability and scheduling control because they show who performed the calibration, when it was approved, whether the instrument passed, and when the next calibration is due.
