Table Structures & Data Types

The core table in the "Maintenance Log (Main)" sheet is structured around a relational design to support efficient data retrieval and reporting. The table includes:

Formulas Required

• =TODAY(): Used to automatically populate the "Date Logged" field when a new entry is added.
• =IF([Status]="Completed", "✅", ""): Adds a green checkmark if status is completed.
• =SUMIFS(Cost Incurred, Status, "Completed"): Sums all maintenance costs for completed tasks in a given quarter.
• =DATEDIF([Date Logged], TODAY(), "d"): Calculates days since last maintenance to trigger alerts.
• =VLOOKUP(Equipment ID, Equipment Master!A:B, 2, FALSE): Retrieves equipment name from the master table for reporting clarity.
• =MONTH(Date Logged) & "/" & YEAR(Date Logged): Formats date to show quarter (e.g., "Mar/2024").

Conditional Formatting

• Red Highlight for High Cost (> $1,000): If the "Cost Incurred" exceeds $1,000, the row turns red to flag significant expenditures.
• Orange for Overdue Tasks: When "Next Due Date" is earlier than today’s date and status is not "Completed", row turns orange.
• Green Progress Bars: For the "Status" column, use data bars to visually represent task completion (e.g., green bar = completed).
• Highlight for Preventive Maintenance: Rows with “Preventive” type are shaded light blue to indicate proactive operations.
