Table Structures and Columns (Main Maintenance Log)

The Main Maintenance Log is structured as a fully dynamic table with the following columns:

Formulas Required

• Maintenance ID Generation: =TEXT(YEAR(TODAY()),"YY")&"-"&TEXT(COUNTA($A$2:$A$1000)+1,"000") — Auto-generates unique IDs in the format MNT-24-XXX.
• Auto-Fill Equipment Name: =IFERROR(VLOOKUP(E2,Equipment_Inventory!$A:$F,2,FALSE),"") — Pulls equipment name based on Equipment ID from the inventory sheet.
• Status Color Coding: Conditional formatting rules (see below) use formulas like =I2="Completed" to highlight green.
• Days Since Scheduled: =IF(D2="", "", DATEDIF(D2,TODAY(),"D")) — Calculates delay in days if maintenance is overdue.

Conditional Formatting Rules

• Overdue Maintenance: If "Date Scheduled" is past today and Status ≠ "Completed", highlight row red.
• High Priority Tasks: If "Maintenance Type" = "Emergency", highlight cell yellow with bold text.
• Status Indicators:
  • Completed → Green background
  • In Progress → Blue background
  • Scheduled → Light gray
  • Canceled → Dark red text, strikethrough
• Labor Time Threshold: If "Hours Spent" > 5, flag in orange for review.
