Table Structures & Columns (Primary Tables)

Sales Projections (Historical & Forecasted) Table:

Maintenance Log Table:

Formulas Required

• Variance Calculation: In the "Forecast Variance" column: =D2-E2 (where D is Forecasted, E is Actual).
• Variance Percentage: In "Variance Percentage": =IF(D2=0, 0, (D2-E2)/D2).
• Maintenance Impact Analysis: Use SUMIFS to count maintenance events per month: =SUMIFS('Maintenance Log'!$H$2:$H$100,'Maintenance Log'!$C$2:$C$100,"Completed", 'Maintenance Log'!$D$2:$D$100, ">= "&A2, 'Maintenance Log'!$D$2:$D\$100, "<= "&EOMONTH(A2, 0)).
• Forecast Accuracy Score: =AVERAGEIFS('Sales Projections'!F:F,'Sales Projections'!F:F,"< 1.2", 'Sales Projections'!F:F,">-0.8") (Measures accuracy within ±20%).
• Conditional Sum: Use SUMPRODUCT to calculate total financial impact of maintenance delays: =SUMPRODUCT((Maintenance Log!$H$2:$H$100="Critical")*(Maintenance Log!$D$2:$D$100>=TODAY()-365)*150) (Assumes $150 per hour delay).

Conditional Formatting Rules

• Variance Percentage: Red if > ±20%, yellow if ±10% to 20%, green if within ±10%.
• Maintenance Status: Orange background for "In Progress", red for "Pending", green for "Completed".
• Forecast Variance: Red font if negative (under-forecast), blue if positive (over-forecast).
• Salesperson Performance: Color scale applied to Forecasted Sales to visualize top performers.
