AP Invoice workflow approval rules, switch from parallel to First Response Wins

Summary:

In BPM, our current AP Invoice Workflow rules are setup as Parallel rules, We are now being asked to change some of your existing rules to use an approval group and the first responder wins rule. I did see read thru Support Document 1999398.1 (First Response Wins ) which provides some VERY High Level information but I am in need of some more detailed information.
