Hi,

Are you confirming that when you add an incident to the related list on the change...that it's parent field on the incident is being set to that change request?

In your second screenshot, it's filtering for the parent field on that incident to show as the change record.

If adding that record to that related list in your first screenshot doesn't actually make that association and update the parent field, then no, it won't show.

Please mark reply as Helpful/Correct, if applicable. Thanks!
