Only Return Work Order Numbers After Amount Is Distributed

You could create a measure like

Shortfall =
SUMX (
    WO2_WorkOrderMaterialDetail,
    VAR QuantityOnHand =
        RELATED ( IM_ItemWarehouse[QuantityOnHand] )
    VAR RequiredAmount = WO2_WorkOrderMaterialDetail[QtyCommitted]
    VAR CurrentDate = WO2_WorkOrderMaterialDetail[WO_Due_Date]
    VAR PreviouslyUsed =
        CALCULATE (
            SUM ( WO2_WorkOrderMaterialDetail[QtyCommitted] ),
            ALLEXCEPT (
                WO2_WorkOrderMaterialDetail,
                WO2_WorkOrderMaterialDetail[ComponentID]
            ),
            WO2_WorkOrderMaterialDetail[WO_Due_Date] < CurrentDate
        )
    VAR AvailableStock =
        MAX ( QuantityOnHand - PreviouslyUsed, 0 )
    RETURN
        RequiredAmount - AvailableStock
)

and then use this in a table visual with the work order number, and filter it to only show when the value is > 0
