Create a purchase order or an outline purchase agreement and maintain the items.

Select the item to be acknowledged by the vendor and enter a confirmation control key in the Deadline monitoring area of the item detail screen.

If the confirmation control key provides for the submission of order acknowledgments by the vendor, and you wish to urge the latter to do so in the event that they are still outstanding after a certain period of time, set the Acknowledgment requirement indicator.

Save the purchase order.
