[dev] How to assign Process to Ticket

I have developed some perl code that, within a Process Management process, automatically creates another ticket and links it to the first one. However, I am not able to figure out how to assign a process to the created/linked ticket. I would like to assign a certain process ID to that ticket so it can be controlled through Process Management. I tried the Process items in the API and they broke my program for some reason. Any ideas would be appreciated. Dan OTRS 3.2.7 Ubuntu 12.04
