Using Shipment Date Edits
On the Purchasing Attributes - Purchasing Controls page, you can specify, at the item level, the number of days a receipt can vary from the scheduled due date indicated on the purchase order. If the receipt date is prior to the due date of the purchase order schedule minus this tolerance value, then the receipt line is identified as early. If the receipt date is past the due date of the purchase order schedule plus this tolerance value, then the receipt line is identified as late.
