Alert is getting automatically unlinked from incidentIssue When an alert is reopened in the system the related incidents are getting automatically unlinked.Why ServiceNow has made such configuration instead of reopening the associated incident? In the note section you see: 'The related alert AlertXXXXX is now unlinked from the incident INCXXXXXX' CauseWorking as expectedResolution1) The incident reference will be removed from the incident by the below script include "EvtMgmtAlertManagementAlertReopenHandler" https://<instance>.service-now.com/nav_to.do?uri=sys_script_include.do?sys_id=8ff399e6b7d920107c038229ce11a9cc 2) This would happen because of the below setting in Event Management Properties. "Reopening alerts will: "Create New Incident" " With this property set to "Create New Incident", it means that there is no need to keep track of the incident when the alert is closed. Removing the incident reference from the alert enables it to create new incident when it gets reopened. 3)Below property is set to create a new incident on the instance OOTB https://<instance>.service-now.com/nav_to.do?uri=sys_properties.do?sys_id=0b018b12eb2211004d7763fba206fe34 -You can change the above property as per your requirement.As per OOTB logic , there is no need to keep track of previous incident on the alert record when a new Incident has to be opened with alert reopen.
