Formulas Required

Last Maintenance Date (Inventory Master):
=IFERROR(INDEX(MaintenanceLog!C:C, MATCH([@Item ID], MaintenanceLog!B:B, 0)), "Never")
This formula pulls the most recent maintenance date from the Log sheet.
Next Due Date (Inventory Master):
=IF(OR([@Status]="Retired", [@Status]="Lost/Damaged"), "N/A", IF([@Maintenance Frequency]="Annually", DATE(YEAR([@Last Maintenance Date])+1, MONTH([@Last Maintenance Date]), DAY([@Last Maintenance Date])), IF([@Maintenance Frequency]="Bi-Annually", DATE(YEAR([@Last Maintenance Date])+0.5, MONTH([@Last Maintenance Date]), DAY([@Last Maintenance Date])), IF(OR(@[@Maintenance Frequency]="Quarterly", [@Maintenance Frequency]="Monthly"), DATE(YEAR([@Last Maintenance Date])+1/4, MONTH([@Last Maintenance Date]), DAY([@Last Maintenance Date])))))
Note: A full formula using DATEADD logic is recommended for accuracy. Consider using a helper column with a lookup table for frequency-to-days conversion.
Warranty Expiry (Inventory Master):
=EDATE([@Purchase Date], 36)
This calculates 3 years from the purchase date.

Conditional Formatting

Overdue Maintenance: Highlight in red if Next Due Date is earlier than today.
Warranty Expiry in 30 Days: Yellow highlight when Warranty Expiry is within the next month.
Status Color Coding: Green for "Active", Red for "Lost/Damaged", Orange for "Under Maintenance".
Low Stock Alert (Optional): If Quantity ≤ 1, highlight in orange.
