Table Structures and Columns

1. Annual Sales Forecast (Sheet 1)

• Column A: Month – Text data type (e.g., January, February… December). Fixed values for each month.
• Column B: Product SKU – Text/Number data type, referencing entries from the Product Master.
• Column C: Historical Sales (Units) – Numeric data type. Contains actual sales volumes from the previous year for benchmarking.
• Column D: Forecasted Sales (Units) – Numeric data type. Calculated using formulas based on trend analysis, seasonality, and growth assumptions.
• Column E: Forecast Variance (% Change) – Percentage data type. Compares forecast vs. actual from prior year to assess accuracy.
• Column F: Growth Rate Assumption – Percentage data type (e.g., 5%). Used to project future demand based on company growth goals.
• Column G: Seasonality Factor – Percentage or multiplier (e.g., 1.3 for holiday season). Applied to adjust forecast based on historical seasonal patterns.

2. Inventory Tracking (Sheet 2)

• Column A: Product SKU – Text/Number, linked to Product Master.
• Column B: Current Stock Level (Units) – Numeric.
• Column C: Safety Stock (Units) – Numeric. Minimum buffer stock to prevent stockouts during supply delays.
• Column D: Reorder Point (Units) – Numeric. Automatically calculated as: (Average Daily Demand × Lead Time in Days) + Safety Stock.
• Column E: Order Quantity (EOQ) – Numeric. Uses the Economic Order Quantity formula to minimize total inventory costs.
• Column F: Next Reorder Date – Date type. Automatically updates based on current stock and forecasted demand.
• Column G: Status – Text (e.g., "In Stock", "Low Stock", "Out of Stock"). Uses conditional formatting to highlight urgency.

3. Product Master (Sheet 3)

• Column A: SKU
• Column B: Product Name
• Column C: Category/Department
• Column D: Lead Time (Days)
• Column E: Cost Price per Unit ($)
• Column F: Selling Price per Unit ($)
• Column G: Supplier Name

Key Formulas Required

• D4 (Forecasted Sales) = C4 * (1 + $F$1) * $G$1: Applies growth rate and seasonality factor to historical sales.
• D5 (Monthly Average Demand) = AVERAGE(C4:C15): Used in EOQ and reorder point calculations.
• D3 (Reorder Point) = (Average Daily Demand × Lead Time in Days) + Safety Stock. Example: =((AVERAGE(C4:C15)/30)*D4)+E4
• E3 (EOQ) = SQRT((2 * Annual Demand * Ordering Cost) / Holding Cost). Uses inputs from Product Master and assumptions.
• G3 (Status) = IF(B3 < D3, "Low Stock", IF(B3 = 0, "Out of Stock", "In Stock"))

Conditional Formatting Rules

• Forecast Variance (% Change): Red text if variance > 15%, yellow if between 5%–15%, green if below 5%.
• Status Column (Inventory Tracking): Red for "Out of Stock", orange for "Low Stock", green for "In Stock".
• Current Stock Level vs. Reorder Point: Highlight cells in red if stock is below reorder point.
• Sales Forecast Trend: Gradient fill based on forecasted units (higher values = darker green).
