Required Formulas for Automation & Accuracy

To ensure the template operates as a true inventory control and maintenance management system, several formulas are embedded to automate workflows and reduce manual errors.

=IF(ISBLANK([@Date Performed]), "", [@[Next Due Date]] + 30) 
=VLOOKUP([@Asset ID], Inventory_Master[Asset ID], MATCH("Last Maintenance Date", Inventory_Master[#Headers], 0), FALSE)
=IF([@Status]="Completed", TODAY(), "") 
=IF(AND([@[Warranty Expiry]] < TODAY(), [@Status] ≠ "Retired"), "Expiring Soon!", "")

Additional formulas include:

• Auto-generated Asset ID: =TEXT(TODAY(),"yyyymmdd")&"-"&TEXT(COUNTA(Inventory_Master[Asset ID])+1,"000")
• Expiry Alert: Conditional formula to flag assets with expiring warranties or overdue maintenance.
• Maintenance Count by Asset: Use COUNTIF across Maintenance Log to track how often each asset has been serviced.

Conditional Formatting for Visual Management

The template leverages conditional formatting to highlight critical statuses at a glance, enhancing visual inventory control.

• Overdue Maintenance: Red fill with white text if "Next Due Date" is before today’s date.
• Warranty Expiring in 30 Days: Orange highlight for items with warranty expiring within the next month.
• Maintenance Status: Color-coded cells: Green (Completed), Yellow (Pending), Red (Overdue).
• Asset Status: Blue background for "Active", gray for "Retired", red for "Out of Service".
