Data Structures & Table Layouts

Sheet 1: Maintenance Log (Main Data Entry)

This is the core data collection sheet where users log every maintenance event. The table spans columns A through H, starting from row 5 (with headers in row 4).

Sheet 2: Asset Inventory

This supporting sheet maintains a complete register of all assets subject to maintenance. It enables data consistency across logs.

Formulas Required

To automate data flow and ensure accuracy, the following formulas are implemented:

• =TEXT(TODAY(), "mm/dd/yyyy"): In the Dashboard to show current date.
• =IF(B5="", "", B5 + G$2): In "Next Due Date" column (G) based on maintenance frequency from Asset Inventory sheet.
• =VLOOKUP(C5, Asset_Inventory!$A:$H, 7, FALSE): To pull the last maintenance date for automatic update in Maintenance Log.
• =IF(DATEDIF(TODAY(), G5, "d") < 0, "Overdue", IF(DATEDIF(TODAY(), G5, "d") <= 7, "Due Soon", "On Schedule")): In the Status column to auto-flag near-due or overdue tasks.
• =COUNTIF(H:H,"Overdue"): Dashboard formula to count overdue entries.
• =SUMIF(D:D,"Preventive", F:F): To calculate total cost of preventive maintenance.

Conditional Formatting Rules

• Overdue Tasks: If G5 (Next Due Date) is earlier than TODAY(), highlight the entire row in red.
• Due Soon: If Next Due Date is within 7 days, apply yellow highlight.
• Status Field: Use color coding: Green for "Completed", Yellow for "Pending", Red for "Overdue".
• Critical Cost Thresholds: Any cost above $500 highlighted in orange.
