This page describes exception workflows associated with single sided trades submitted for affirmation and clearing. These are the alternate uses cases where a trade submitted for affirmation and clearing can be rejected by CME ClearPort or can be cancelled before it is cleared or voided after it is cleared. The variation in workflows based on the transport used for submitting these trades is also described here.
