Hi @bhavyaa30
Thanks for your participation. The code looks good, but this is something ServiceNow provides out-of-the-box (OOTB). When the parent-child incidents are synced, the OOTB Incident Close process runs and automatically closes the parent incident once all child incidents are already in a resolved state."
