Table Structures and Columns (Product Supply List - Weekly)

The core table in the "Product Supply List (Weekly)" sheet is structured to support weekly planning cycles with dynamic updates. The table spans from Column A to Column H, with headers starting at Row 3.

Formulas Required

• Forecasted Demand (D3): Uses a weighted moving average formula across the last 4 weeks of historical data: =AVERAGEIFS(HistoricalSalesData!$B:$B, HistoricalSalesData!$A:$A, A3, HistoricalSalesData!$C:$C, "<="&TODAY(), HistoricalSalesData!$C:$C, ">="&(TODAY()-7)) This calculates weekly sales trends and projects demand for the current week.
• Required Supply Quantity (E3): =MAX(0, D3 - C3) Ensures no negative order quantities are generated.
• Predicted Stock Level (Optional Column I): =C3 + E3 - D3 Shows expected stock level after this week’s forecast and supply delivery.
