Formulas and Automation

• Auto-generated Work Order ID: =CONCATENATE("MO-", YEAR(TODAY()), "-", TEXT(MONTH(TODAY()),"00"), "-", TEXT(COUNTA('Maintenance Log'!A:A), "0000"))
• Next Maintenance Due: =IF([@Last Maintenance Date]="", "", DATE(YEAR([@Last Maintenance Date]), MONTH([@Last Maintenance Date])+12, DAY([@Last Maintenance Date])))
• Time Spent (Auto-Calculate): =IF(OR(ISBLANK(Date Assigned), ISBLANK(Date Completed)), "", (Date Completed - Date Assigned) * 24)
• Total Cost: =IF(OR(ISBLANK([@Time Spent]), ISBLANK([@Parts Cost])), 0, [@Time Spent] * [@[Hourly Rate]] + [@Parts Cost])
• Pivot Tables: Used to aggregate work orders by category, priority, location, and technician.

Conditional Formatting Rules

• Critical Priority Tasks: Red fill with white text – applied when “Priority Level” = “Critical”.
• Overdue Maintenance: Orange background if “Next Due Maintenance” is earlier than today.
• Average Resolution Time Exceeded: Yellow highlight for tasks taking more than 72 hours to complete (based on industry benchmark).
• Status Change Alerts: Green text when status changes from “New” to “In Progress” (tracked via conditional logic in a separate tracking column).
