Table Structures and Data Types

The template utilizes relational data structures across sheets to maintain accuracy and reduce redundancy. Each table is structured with primary keys for referential integrity.

Inventory Master

• SKU_ID (Text, Primary Key): Unique product identifier.
• Description (Text): Product name or category.
• Category (Text): E.g., Electronics, Apparel, Packaging.
• Unit of Measure (Text): e.g., pcs, kg, cartons.
• Reorder Level (Number): Minimum stock before triggering a reorder.
• Max Stock Level (Number): Upper limit to prevent overstocking.
• Lead Time (Days, Number): Days required to receive new inventory.
• Current Stock (Number): Real-time quantity on hand.
• Last Updated (Date/Time): Timestamp of last stock adjustment.

Daily Transactions

• Transaction_ID (Text, Primary Key)
• SKU_ID (Text, Foreign Key)
• Type (Text): Inbound, Outbound, Return
• Quantity (Number)
• Date (Date/Time)
• Location (Text): Warehouse A, B, or C
• Supplier/Order ID (Text, Optional)

Resource Allocation

• Resource_ID (Text): e.g., Worker ID, Forklift No.
• Type (Text): Staff, Equipment, Vehicle
• Status (Text): Available, On Duty, Maintenance
• Assigned To (SKU or Location)
• Start Time / End Time (Time)
• Daily Hours (Number)

Formulas Required

The template includes a suite of dynamic formulas that drive its functionality:

• Inventory Master – Current Stock Update: Uses SUMIF from Daily Transactions to calculate current stock based on inbound/outbound flows.
• Demand Forecasting (Using moving averages): A formula like `=AVERAGE(OFFSET($D$5,0,-4,4))` calculates 3-month average demand for forecasting.
• Reorder Alerts: If `Current Stock < Reorder Level`, a formula returns "REORDER REQUIRED" in the alert column (e.g., `=IF(C2<B2,"REORDER REQUIRED","OK")`).
• Stock Turnover Ratio: `=SUMIFS(InventoryMaster[Sales], InventoryMaster[Date], >="2024-01-01") / Average Stock` for each product.
• Resource Utilization: `=SUMIF(ResourceAllocation[Daily Hours], ">", 8) / Total Days` to identify overworked staff.

Conditional Formatting

To enhance visual clarity and user interaction, conditional formatting is applied throughout the template:

• Stock Alerts: Cells in "Current Stock" below Reorder Level turn red with a warning icon.
• High Demand Products: Rows where demand forecast exceeds 100% of average are highlighted in orange.
• Scheduled Maintenance: In "Resource Allocation," any status showing “Maintenance” is shaded in gray with a tooltip.
• Negative Inventory (errors): Any negative stock value triggers a yellow background and bold text for immediate attention.
