How to track scheduled transport's owner?

Prior to audit requirement,basis has been asked by auditor to provide all the selected transport lists and the name of the transporters for each selected transports.The problem is,most of the transports have been done using user TMSADM (Scheduled transport) and transporter cannot be tracked using SE16 and tplog because for sheduled transport,TMSADM will be captured as a transporter. Anybody here can advise me on how to track the real id of those who schedule the transport?
