Have you ever noticed that Service Requests have the user input from the portal on the front of the ticket but Incidents don’t. If you’re like most users of SCSM you have probably extended the incident or service request class with some generic fields so you can ask more questions on the portal and have fields to map to, if not I’ll save that for another post.
When I am dealing with Review Activities in Service Manager I always use Orchestrator to populate the reviewers. I try to hard code as little as possible into the templates so I have to maintain as little as possible. One requirement that I was given for a change management project I worked on was to use an AD group that would contain CAB voting members and use that group to populate the CAB review activity. One caveat to that was, no matter how big the AD group got, only 3 approvers where needed. The problem is, a review activity sets the approval threshold by percentage. If we had 10 possible CAB voters then I could set the threshold to 30% but if we added an additional 2 or 3 users to that group then 30% would no longer work and I’m not going to babysit that template as people come and go.
