Our purchasing manager would like to see a 2nd due date on the purchase order line items, similar to the 2nd est. ship date on sales orders. He's like to be able to track our vendors 1st est. ship date against when they actually get it out. Our sales people use the est. due date to inform our customers when a backorder will ship, therefore purchasing cannot leave that date "as is" after a vendors due date has come and gone and no product has arrived.
