This function cancels a queued transaction. For a transaction that has not started executing or is currently executing, this function will generate an XHTML document showing that the transaction was cancelled. That document is also stored as the result of the transaction. This cancellation document will be in the same format as the report that is produced if the Arbortext PE sub-process terminates or there is some other serious error preventing a transaction to finish.

If this function is applied to an executing transaction, the Arbortext PE sub-process used by the transaction will be terminated.

If this request specifies an immediate request, a queued transaction that has completed, or does not identify an active transaction, this function will return an error.
