Editor's Notes

  • 1.) Shipping qty is less than invoice qty. (Invoice & Shipping file).
    Pivot of both tables in a new sheet.
    First Column of pivot Invoice number and second of sum of Invoice Qty.
    Vlookup the quantity between the two pivots

    2.) For one transaction in the year the sale price is exorbitant or one order with huge quantity. (Invoice & Shipping file).
    Add pivot to show material column
    Then Avg price of Per piece,
    Then Max of per Piece,
    Min of Per Piece.

    3.) Last days ordering necessarily does not mean it would result in invoicing. (No Practical)
