Hi,
For implementing this scenario, u need to insure that all intermediate responses have conversation id with them. this will insure synchronisation of responses for unique processes.
For implemeting BPM with TN, u can use model template provided by webMethods - One way, two way etc according to requirement. U can use wmtn services for processing documents in model generated flow steps.
Regards,
Pushkar
