Formulas Required

1. Next Expected Arrival Date:

   =IF([@PO Date Placed]="", "", WORKDAY([@PO Date Placed], [@Lead Time Days]))

2. Stock Status Indicator:

   =IF([@Current Stock Level] <= [@Reorder Point], "CRITICAL", IF([@Current Stock Level] <= [@Optimal Stock Level]*0.7, "LOW", "OPTIMAL"))

3. Days Until Reorder Needed:

   =IF([@Current Stock Level] <= [@Reorder Point], 
                IF([@Demand Rate Per Day] > 0, ROUND(([@Reorder Point] - [@Current Stock Level]) / [@Demand Rate Per Day], 0), "N/A"),
                "OK")

4. Inventory Turnover Ratio:

   =IF(SUM([@Total Cost of Goods Sold]) > 0, 
                SUM([@Total Cost of Goods Sold]) / AVERAGE([@Current Stock Level]), 0)
