Maintenance Log – Table Structure & Data Types

Formulas & Automation

• Auto-generated Maintenance ID: Uses =TEXT(TODAY(),"yyyymmdd")&"-"&COUNTA($A$2:$A$1000)+1
• Next Due Date: Formula: =IF([@Last Completed Date]="", "", [@Last Completed Date] + [@[Frequency (Days)]])
• Status Logic: Uses nested IFs to auto-flag overdue tasks: =IF(AND(@[Next Due Date]<=TODAY(),[@Status]<>"Completed"),"Overdue","Pending")
• Duplicate Detection: Conditional formatting rule highlights duplicate Maintenance IDs.

Conditional Formatting Rules

• Overdue Tasks: Red fill with white text (if Next Due Date < Today and Status ≠ Completed)
• Due in 7 Days: Orange fill (if Next Due Date is within 7 days from today)
• Status Highlighting: Color-coded cells for each status: Blue for Pending, Green for Completed, Red for Overdue
• Frequent Repeat Tasks: Light yellow background if Frequency (Days) < 30
• Audit-Required Items: Border with bold red outline if Audit Flag = Yes
