Repair JobOper Hours and Costs?

Can anyone tell me what this process does? I ran it in test and am trying to see what changed. I pulled up the log and it adjusted 14 jobs it said. When I look at the jobs and operations listed, I can’t see a difference between my test system and the production system. Any ideas on where I should look to see those changes?

Did you ever find out what this process does?
I am still trying to figure out my negative actual hours issue, and our Epicor support suggested we run this process. Still waiting on it to finish (15+ minutes in).
