1. Warehouse Inventory Master

2. Stock Movement Log

Data Types and Integrity Rules

• SKU_ID: Text, primary key (unique identifier)
• Units in Stock: Integer, non-negative only (validated via data validation)
• Avg. Daily Demand: Decimal (2 places), required for forecasting
• Reorder Level: Integer, must be ≥ 1
• Status: Dropdown list: "In Stock", "Low", "Critical", "Out of Stock"
• All dates are in standard ISO format (YYYY-MM-DD HH:MM).

Formulas Required

• Stock on Hand (Daily): =IF([Units in Stock] > [Reorder Level], "In Stock", IF([Units in Stock] < [Reorder Level], "Low", "Critical"))
• Safety Stock Calculation: =AVERAGE([Avg. Daily Demand]) * 2
• Days to Reorder: =IF([Units in Stock] >= [Reorder Level], "", (Reorder Level - Units in Stock) / Avg. Daily Demand)
• Forecasted Stock (Next 30 days): =Units in Stock + (Avg. Daily Demand * 30) - (Outbound Quantity from Movement Log)
• Stock Turnover Ratio: =Sales Volume / Average Inventory Value
• Total Value of Inventory: =SUM(Units in Stock * Unit Cost)

Conditional Formatting Rules

• Critical Low Alerts: Red background for items where Units in Stock ≤ Reorder Level.
