Table Structures & Column Definitions (Inventory Master Data)

Formulas Required for Automation and Accuracy

• Inventory Valuation: =SUMIFS('Location-Based Stock Levels'!C:C, 'Location-Based Stock Levels'!A:A, InventoryMasterData!A2) * InventoryMasterData!E2 – Calculates total value per SKU across all locations.
• Stockout Indicator: =IF(SUMIFS('Location-Based Stock Levels'!C:C, 'Location-Based Stock Levels'!A:A, InventoryMasterData!A2) < InventoryMasterData!F2, "Alert", "OK") – Flags SKUs below safety stock.
• Reorder Quantity: =IF(InventoryMasterData!F2 > SUMIFS('Location-Based Stock Levels'!C:C, 'Location-Based Stock Levels'!A:A, InventoryMasterData!A2), InventoryMasterData!G2 - SUMIFS('Location-Based Stock Levels'!C:C, 'Location-Based Stock Levels'!A:A, InventoryMasterData!A2), 0) – Calculates how much to reorder.
• Inventory Turnover Ratio: =ROUND(SUM('Transaction Log'!G:G)/AVERAGE(SUMIFS('Location-Based Stock Levels'!C:C, 'Location-Based Stock Levels'!A:A, InventoryMasterData!A2), SUMIFS('Location-Based Stock Levels'!D:D, 'Location-Based Stock Levels'!A:A, InventoryMasterData!A2)), 2) – Based on cost of goods sold (COGS) and average inventory.
• Forecast Accuracy: =IFERROR(1 - ABS('Actual'-'Forecast')/'Forecast', 0)

Conditional Formatting Rules

• Stockout Alerts: Red fill with white text for any row where stock level is below safety stock.
• High Stock Risk: Orange highlight for SKUs exceeding 150% of average monthly usage to flag overstocking.
• Critical Reorder Point: Yellow fill with black text for items within 3 days of reorder point.
• Trend Indicators in Dashboard: Green (upward) and red (downward) arrows based on month-over-month change in stock levels.
