Promised Ship Date

The promised ship date indicates the date when an item should be shipped to the customer. Must not be less than the system date or greater than the entered due date.  If the promised ship date is not entered, it defaults to a calculated date.  The calculated promised ship date is the due date minus the requisition lead time (Category D17) for the Supplying/Receiving warehouse combination.  This calculation must not result in a date less than the system date.  If no record is found for Reference Category D17, the In-Transit Lead Time defaults to one day, and a warning message is sent to the system operator.  

This field also represents the date the shipment will be shipped from the vendor's site.  This date will default to the promised ship date on the PO release.  In the case of direct distribution, if the purchase order line is associated with a sales order line, this value will also default to the sales order line.
