Active Problem Ticket gets closed when linked Incident is closed

[LinMeyer]

Hi there

We have an issue where Problem tickets are being closed when the linked Incident / Related record (example Change Requests) is closed. According to feedback I have received, this is out of the box default behavior in ServiceNOW. However I do not believe this to be correct. Based on researched I did on best practice and how Problems work in ServiceNOW this behavior points to config that was put into place to close the related records. Can anyone shed some light on this for me? We are using Washington instance

Hi, can you replicate this issue in a PDI? if yes then definitely OOB behavior but I cannot replicate in a PDI.

OOB Incident has a many to 1 relationship with problem, and so I would not expect 1 incident to close its related problem as the problem may be related to other open incidents.
This KB article also suggests OOB expected behavior is Incidents will close based on problem closure

To diagnose I would start by reviewing BR's, the expectation would be an after or async BR but I would check before as well.

You could also check Flow\workflow contexts for flow\workflow that may have triggered against the Incident during it's lifecycle.

If you can't find the cause there, then while unlikely a script action (triggered by a sysevent) could potentially also be used to drive the behavior.
