Our problem Manager wants any incidents that are attached to a Problem to be resolved when the problem is closed. I found an Article which described putting in a precondition on the Open Status of the incident process which checks if Problem is closed, if yes resolve child incidents, but I came across a number of issues with this.
Cannot add this as their is already a resolve on creation precondition which has a resolve Auto Action (so we get an error on the process cannot save process as there are multiple AutoResolve Actions on the Open Status)
If I remove the resolve on creation and replace with the Problem Closed Pre-Condition any new Incidents created are automatically Resolved
The other issues I can see if that you have to assume Incidents will be in the Open status. The linked option above may work or you could try scheduling a job to close any Incidents that have a Problem parent and it's closed.
