You must have the necessary permissions to cancel purchase orders and to search for orders.

When you cancel a purchase order, a new version of the associated requisition, identified by a version number such as V2, is created and submitted for approval. The cancel order is noted on the History tab of the new version; the deleted items are listed in the Deleted Lines section on the Summary tab. If the canceled order was the only or last order for the associated requisition, the requisition's status changes to Canceled when it is approved.

You can cancel only orders whose status is Ordered or, from Ariba Supplier Network (Ariba SN), Confirming, Confirmed, or Shipping.

If necessary, purchasing agents or other authorized users can use the Force Cancel command to intervene when there are problems canceling a direct order.
