By default, PO's are initially created with a status of released. Most status changes are implemented by the system; for example, the status is changed to Printed when a Released or Changed PO is successfully printed. Printing a PO with a status of Pending Cancelled will reset its status to Cancelled.
Other status changes can be made directly by the user by double-clicking on a new status (the system will not allow you to make an illegal status change). Any necessary postings or reversals will also be handled by the system even if the status is not changed, but the number of items on a PO, as is the case of the quantity of items in a PO with a status of Released without changing the status.
