• =IF(MonthlyForecast!F2 > CurrentInventory!C2 + PurchaseRequisitionTracker!E:E, "Critical", IF(MonthlyForecast!F2 > CurrentInventory!C2, "Low Stock", "Adequate")) – Flags inventory status based on forecast.
• =AVERAGEIFS(HistoricalData!F:F, HistoricalData!B:B, A2, HistoricalData!C:C, B2) – Calculates rolling average sales for product/region to support forecasting.
• =COUNTIF(PurchaseRequisitionTracker!$C:$C,"Pending") – Displays total pending purchase requests on Summary dashboard.

Conditional Formatting

To improve visibility and urgency tracking:

• Stock Levels: Red for "Critical" (forecast > current stock + 30% buffer), Yellow for "Low Stock", Green for "Adequate".
• Purchase Status: Orange fill with bold text for pending POs.
