On occasion, the date scheduling parameters for an SLA may expire or become invalid. Here are a couple of examples of when this can occur...
The SLA job runs on a calendar that runs out of days
The schedule in CA7 is modified to where the triggering job for an SLA no longer triggers the SLA job.
When this situation occurs, the SLA no longer tracks in iDash and no alert is generated as a result. This document provides some methods for identifying SLAs that are in this condition so that corrective action can be taken.
