  Check the Purchase Order: Verify the quantities in the PO to ensure they are correct. If the PO quantity is indeed less than the invoice quantity, you may need to adjust the PO.

  Adjust the Invoice Quantity: If the invoice quantity is incorrect, you can correct it to match the PO quantity or the quantity that has been received.
  Create a New Purchase Order: If the invoice is for additional quantities that were not part of the original PO, consider creating a new PO for the additional items.
  Consult with Procurement: If there are discrepancies, it may be necessary to consult with the procurement department to resolve any issues related to the order or delivery.
