2. 2. Historical Sales Data: Stores past monthly sales figures to support data-driven forecasting.
3. 3. Product Master List: Maintains a centralized database of all products with key attributes such as lead time, safety stock, and unit cost.
4. 4. Inventory Status: Tracks current on-hand inventory levels and upcoming deliveries for real-time supply visibility.
5. 5. Dashboard & Charts: Visual summary of key performance indicators (KPIs) such as forecast accuracy, stockout risk, and reorder status.

Table Structures and Columns

Sheet 1: Monthly Supply Forecast

This sheet serves as the central hub for monthly planning. It features a structured table with the following columns:

Sheet 2: Historical Sales Data

A chronological record of monthly sales by product. This supports the forecasting engine.

Formulas Required

• Forecasted Units Calculation:
  Use a combination of moving average or linear trend analysis (e.g., =FORECAST.LINEAR) based on historical data. Example: =FORECAST.LINEAR(1, Historical_Sales_Range, Month_Index_Range)
• Recommended Order Qty:
  =IFERROR(Forecasted_Units + Safety_Stock - On_Hand_Inventory, 0) This ensures no negative order values.
• Reorder Point:
  =Safety_Stock + (Average_Daily_Sales * Lead_Time_Days)
• Status Indicator:
  Conditional logic using nested IF and ABS functions to compare forecast vs. actuals: =IF(ABS(Forecasted_Units - Actual_Units)/Actual_Units <= 0.1, "On Track", IF(ABS(...) <= 0.25, "At Risk", "Critical"))

Conditional Formatting

To enhance readability and highlight critical data points:

• Forecasted Units: Color scale from green (low) to red (high).
• Status Column: Red fill for “Critical”, yellow for “At Risk”, green for “On Track”.
• Safety Stock vs. On-Hand Inventory: Highlight in red if on-hand is below safety stock level.
