Table Structures and Columns

1. Maintenance Log (Main)

This is the primary data collection sheet where technicians or operations managers record every maintenance event.

2. Equipment Master List

This sheet stores all asset information for reference across the template.

Formulas Required

• Next Due Date (Maintenance Log):
  =IF([@[Service Frequency]]="Monthly", DATE(YEAR([@Date Recorded]), MONTH([@Date Recorded])+1, DAY([@Date Recorded])), IF([@[Service Frequency]]="Quarterly", DATE(YEAR([@Date Recorded]), MONTH(@[Date Recorded])+3, DAY(@[Date Recorded])), IF([@[Service Frequency]]="Semi-Annually", DATE(YEAR(@[Date Recorded]), MONTH(@[Date Recorded])+6, DAY(@[Date Recorded])), IF([@[Service Frequency]]="Annually", DATE(YEAR([@Date Recorded]), MONTH([@Date Recorded])+12, DAY(@[Date Recorded])), ""))))
• Warranty Status (Equipment Master List):
  =IF([@[Warranty Expiry]]TODAY()+30, "Valid - Long Term", "Valid - Approaching"))
• Last Service Date (Maintenance Log):
  =MAXIFS(MaintenanceLog[Date Recorded], MaintenanceLog[Equipment ID], [@Equipment ID]) — used in Equipment Master List.

Conditional Formatting

• Overdue Tasks (Maintenance Log): Highlight rows where Date Recorded > Next Due Date AND Status ≠ Completed.
• High Priority & Critical Issues: Apply red fill for priority levels "High" and "Critical".
• Downtime Alert (Dashboard): Use data bars to visualize downtime hours—longer bars indicate higher impact.
• Warranty Expiry in 30 Days: Color-code rows in Equipment Master List with warning shade if warranty expires within the next month.

User Instructions

1. Open the template and ensure macros are enabled (if applicable).
2. Start by populating the Equipment Master List with all assets.
3. Add maintenance records in the Maintenance Log, ensuring correct Equipment ID and dropdown selections.
4. The system auto-fills Next Due Date and pulls service frequency from the master list.
5. Use the Dashboard & Insights sheet to review trends: total downtime, recurring issues, cost per equipment type.
6. Set reminders based on upcoming scheduled tasks in the Maintenance Schedule.
7. Add new rows as needed; no manual reformatting required—template adjusts automatically.
