The purpose of the Cancel PurchaseOrder is to communicate from one business application to one or more other business applications that a previous Purchase Order or Purchase Order line is no longer needed.

Processing Note: This cancel must refer to the original document and/or item ordered. To cancel the entire order, include only the Purchase Order Header information for the instance of the Purchase Order you wish to cancel. To cancel a line or several lines, each line to be cancelled must be included.

This BOD commonly causes updates to occur and may be used as part of a larger integration scenario or as a single tool for communicating demand.
