Table Structures and Columns

Sheet 1: Inventory Timeline & Gantt View (Core Gantt Chart)

Sheet 2: Item Master List (Inventory Control Database)

Data Types & Formulas Required (Critical for Automation)

• Date Columns: Use Excel’s date format (mm/dd/yyyy). Ensure cells are formatted as "Short Date".
• Status Logic: Formula in Status column: =IF(TODAY() > End_Date, "Late", IF(TODAY() >= Start_Date, "In Progress", "Pending"))
• Progress Calculation: Use: =IF(End_Date="", "", IF(TODAY() >= End_Date, 100%, MIN(100%, (TODAY()-Start_Date)/MAX(1, (End_Date-Start_Date)) * 100)))
• Reorder Flag: In Item Master List: =IF(Current_Stock <= Reorder_Point, "REORDER NEEDED", "OK")
• Critical Path Detection: Use conditional logic to flag long-duration tasks exceeding 14 days.

Conditional Formatting Rules (For Visual Clarity)

• Status Colors: Red for "Late", Yellow for "In Progress", Green for "Completed". Apply to the Status column.
• Overdue Tasks: Highlight rows where today’s date exceeds the End Date with red fill and bold text.
• Safety Stock Alerts: In Item Master List, highlight cells where Current Stock ≤ Safety Stock using a red conditional rule.
• Gantt Bar Visuals: Use "Data Bars" in the Gantt view to represent task duration (from Start to End), with color gradients indicating progress.

User Instructions

1. Begin by populating the Item Master List, ensuring every SKU is correctly defined with safety stock and reorder point.
2. Enter all procurement, warehousing, and shipment tasks in the Inventory Timeline & Gantt View. Use consistent dates and task IDs.
3. Link items from the Item Master List to their corresponding Gantt tasks via the "Item Name" or "SKU" field.
4. The system auto-calculates progress, status, and reorder flags based on today’s date (TODAY() function).
5. Regularly update current stock levels in the Stock Movement Tracker to maintain accuracy across dashboards.
6. Review the Dashboard & KPIs weekly to identify bottlenecks, overdue tasks, or inventory shortages.

Example Rows (Illustrative)

Gantt Chart Entry:

• Task ID: I001-PO
  Item Name: Steel Pipes – 2-inch
  Description: Purchase Order #PO23456 from Supplier XYZ

  End Date: 11/30/2024
  Status (Auto): In Progress (if today is between 11/5 and 11/30)
  Progress: 67% (calculated if today is November 20, 2024)

Recommended Charts & Dashboards

• Gantt Chart Visualization: Use Excel’s built-in stacked bar chart to show task timelines with progress bars.
• Inventory Health Dashboard: Include a combination of pie charts (stock by category), bar graphs (reorder alerts), and line charts (trends in stock levels over time).
• KPI Cards: Display key metrics like: Days of Inventory on Hand, Stock Turnover Rate, Order Fill Rate, Number of Overdue POs.
• Timeline Heatmap: Use conditional formatting across a date grid to show which days have the highest inventory movement or procurement activity.
