Formulas Required

The "Data Version" format emphasizes automation. The following formulas are essential:

• =SUMIFS('Data Input (Raw)'!$D:$D, 'Data Input (Raw)'!$A:$A, ">="&B2, 'Data Input (Raw)'!$A:$A, "<="&(B2+6)): Sums actual sales for a specific week.
• =IFERROR(AVERAGEIFS('Data Input (Raw)'!$D:$D, 'Data Input (Raw)'!$B:$B, B13, 'Data Input (Raw)'!$A:$A, ">="&DATE(YEAR(B2),MONTH(B2),1), 'Data Input (Raw)'!$A:$A, "<="&EOMONTH(B2,0)), 0): Calculates average weekly sales by product for forecasting.
• =ROUNDUP([@Budgeted Sales] * (1 + [Forecast Adjustment]), 2): Applies a dynamic adjustment factor based on market trends or performance indicators.
• =IF([@Actual Sales] > [@Forecast], "Over", IF([@Actual Sales] < [@Forecast], "Under", "On Target")): Categorizes performance for conditional formatting.

Conditional Formatting Rules

• Performance Status: Color-codes forecast accuracy: Green = Over, Yellow = On Target, Red = Under.
• Variance Percentage: Applies gradient fill to highlight variance % between actual and budget (e.g., dark red for -20%, green for +20%).
• Forecast Trend: Highlights weeks where forecast exceeds historical average in bold blue text.
