Table Structures and Columns

Maintenance Log (Master)

This sheet serves as the central repository for all maintenance activities on inventory items. Each row represents a unique maintenance event.

• Item ID: Text/Number (Unique identifier for each inventory item)
• Asset Name: Text (e.g., Conveyor Belt A, Pump 3B)
• Maintenance Type: Dropdown (Preventive, Corrective, Predictive, Calibration)
• Date Performed: Date
• Due Date (Next Scheduled): Date
• Last Maintenance Date: Date
• Status: Dropdown (Completed, Pending, Overdue, Cancelled)
• Maintenance Technician: Text or Named List (for team tracking)

Inventory Tracking

This sheet maintains real-time data on inventory levels and usage patterns.

• Item ID: Text/Number (links to Item Master Data)
• Description: Text
• Category: Dropdown (e.g., Tools, Consumables, Machinery Parts)
• Total Quantity On Hand: Number
• Safety Stock Level: Number (minimum threshold for reordering)
• Last Reorder Date: Date
• Reorder Point (Trigger): Formula = Safety Stock Level + 10% of Average Monthly Usage
• Status: Conditional (e.g., "Low Stock" if On Hand ≤ Reorder Point)

Planning View (Calendar & Forecast)

This is the cornerstone of the Planning View, providing a visual calendar-based layout that overlays inventory levels and upcoming maintenance events.

• Date: Date (Daily entries from current month to 12 months ahead)
• Item ID: Text/Number
• Maintenance Due Today: Boolean (Y/N based on due date = today)
• Pending Maintenance Count: Number (count of upcoming tasks within 7 days)
• Inventory Level Change: Number (e.g., +5 for delivery, -3 for usage)

Item Master Data

A reference sheet that holds static information about each inventory item.

• Item ID: Text/Number (primary key)
• Description: Text
• Type (Asset/Consumable): Dropdown
• Lifecycle Duration (Months): Number
• Maintenance Interval (Days): Number (how often maintenance is required)

Dashboards & KPIs

This sheet offers real-time performance monitoring through visual charts and summary statistics.

Formulas Required

• Reorder Point (Inventory Tracking):
  =Safety_Stock + (Average_Monthly_Usage * 0.1)
• Status in Inventory Tracking:
  =IF([@Total Quantity On Hand] <= [@Reorder Point], "Low Stock", "Normal")
• Next Due Date (Maintenance Log):
  =DATE(YEAR([@Date Performed]), MONTH([@Date Performed]) + [@[Maintenance Interval (Days)]/30, DAY([@Date Performed]))
• Overdue Status:
  =IF(AND([@Due Date (Next Scheduled)] < TODAY(), [@Status] <> "Completed"), "Overdue", "")
• Calendar View: Maintenance Due Today:
  =IF([@Date] = TODAY(), IF(COUNTIFS(MaintenanceLog[Due Date (Next Scheduled)], TODAY(), MaintenanceLog[Status], "<>Completed") > 0, "Yes", "No"), "")
• Pending Count:
  =COUNTIFS(MaintenanceLog[Due Date (Next Scheduled)], ">="&TODAY(), MaintenanceLog[Due Date (Next Scheduled)], "<"&TODAY()+7, MaintenanceLog[Status], "<>Completed")
• Dashboards: % Overdue Tasks:
  =COUNTIFS(MaintenanceLog[Status], "Overdue") / COUNTA(MaintenanceLog[Item ID])

Conditional Formatting

• Overdue Tasks: Highlight in red if due date is before today and status ≠ Completed.
• Low Stock Items: Use yellow fill with dark text for items where On Hand ≤ Reorder Point.
• Maintenance Due Within 7 Days: Shade green background for tasks due within one week.
• Calendar View – Due Today: Color cells red if a maintenance task is due today.

User Instructions

1. Begin by populating the Item Master Data sheet with all inventory items, including their type and expected lifespan.
