Main Maintenance Log: Data Collection Core
This sheet is the heart of the Data Collection system. It records every maintenance activity with full traceability.| Column Name | Data Type / Format | Description / Validation Rules |
|---|---|---|
| Maintenance ID (Auto-Generated) | Text (e.g., ML-2024-1057) | Unique alphanumeric identifier generated automatically using a formula combining year, month, and sequential number. |
| Date of Entry | Date (dd/mm/yyyy) | System date when record is created. Default: =TODAY() |
| Asset ID | Text (Linked from Asset Register) | Dropdown list populated from the Asset Register sheet. Ensures data integrity and consistency. |
| Asset Name | Text | Fetched via VLOOKUP from Asset Register based on Asset ID. Read-only after entry. |
| Maintenance Type | Dropdown: Preventive, Corrective, Predictive, Routine, Emergency | Ensures standardized categorization for future analysis. |
| Description of Work Performed | Long Text (Up to 1000 characters) | Free-form field for technician notes. Includes details like parts replaced, procedures followed. |
| Date of Maintenance | Date (dd/mm/yyyy) | Actual date work was completed. |
| Planned vs. Actual Duration (hours) | Numeric (decimal, 0.5 precision) | Used for efficiency analysis. Planned duration comes from the Maintenance Schedules sheet. |
| Technician Name | Text (Dropdown: List of authorized staff) | Limited to pre-registered personnel for accountability. |
| Status | Dropdown: Completed, Pending, Cancelled, On Hold | Tracks workflow progress. Affects dashboard metrics. |
| Cost of Maintenance ($) | Currency (USD format) | Numeric field with $ symbol. Used for budget tracking. |
| Next Due Date | Date (dd/mm/yyyy) | Auto-calculated using formula based on maintenance type and frequency from the Maintenance Schedules sheet. |
Formulas & Automation
The template uses advanced Excel formulas to maintain data integrity and enable dynamic updates:- Maintenance ID Generation:
=TEXT(TODAY(),"yyyy-mm")&"-"&TEXT(ROW()-1,"0000") - Asset Name Lookup:
=IFERROR(VLOOKUP(A2,AssetRegister!A:B,2,FALSE),"") - Next Due Date:
=IF(OR(MaintenanceType="Preventive",MaintenanceType="Routine"),DATE(YEAR(DateOfMaintenance),MONTH(DateOfMaintenance)+FrequencyInMonths,DAY(DateOfMaintenance)),DateOfMaintenance) - Status Color Coding: Conditional formatting based on status (red for "Pending", green for "Completed").
Conditional Formatting Rules
- Overdue Maintenance: IfDate of Maintenance + 14 days < TODAY(), highlight row in orange.
- Critical Assets: If Asset ID is flagged as "High Critical" in the Asset Register, apply bold font and blue background.
- Budget Exceeded: If Cost > $500, color cell red with white text for emphasis.
User Instructions
