It is not possible to amend the 'Broker ID' field in a trade confirmation which has previously been submitted to CMS for eCM naming another Broker.

In order to amend the Broker ID of an eCM submission you must Manually Terminate the incorrectly submitted CNF, then submit the corrected CNF with a new Trade ID to reinitiate the Matching Dialogue for the Trade.
