Hi @swatis22

https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1116348

Issue

The "Activity Due" field is showing as "UNKNOWN" instead of a date.

Cause

By default, Inactivity monitor is only created for Priority one incidents. Hence all other non p1 Incidents show "Activity due" as 'Unknown'

/nav_to.do?uri=sysrule_escalate_am.do?sys_id=34a17cb4c61122b7006b897258cbd702

Resolution

The "Activity Due" field will be updated based on the "Wait" field on the Inactivity monitor.

For more details on the Inactivity monitor, Please refer to the below document.

@swatis22

since you are talking about Requests, that field as per KB shared by Atul gets populated only for P1 incidents

If you want to populate it for Requests, then you need to create inactivity monitor for sc_request table

check this but it will only populate for new records and not for older REQs

You can follow the KB article and modify the logic as per your requirements.

Hi @swatis22

You must be checking non-P1 incident. It is expected behaviour.

Inactivity monitor is only created for "Priority One Inactivity" incidents.

Hence all other non p1 Incidents show "Activity due" as 'Unknown'.

HI @Tanushree Maiti ,
"Priority One Inactivity" is for incidents but I am facing the issue in request table, there it is showing unknown. How do I fix this?

Hi @swatis22

By default, in oob ServiceNow instances, inactivity monitors are only created for Priority 1 (P1) incidents, which is why other tasks may show "Unknown" for activity_due.

The activity_due field in ServiceNow is a date/time field (inheriting from the task table) that works in conjunction with Inactivity Monitor to track when a record requires an update.

Similar to incident, if you configure Inactivity Monitor for Request for specific condition, for those condition, activity_due will be populated.
