Task not getting created in SLA in CRM 2015
We had created a new enhanced SLA which had an SLA item having an email in Success Actions and a task in Failure Actions.
Neither the email was sent nor the task was getting created.
Select Resolve By KPI in SLA KPI
Default value selected in SLA KPI is First Response by KPI
Changing SLA KPI from First Response by KPI to Resolve By KPI solved the issue
