How to setup alert for missed backup schedule in opscenter

Hi,

We are using netbackup 7.5.0.5. I want to know is there a way to set up alerts for skip backup schedule in opscenter. Recently a full backup job was missed, we checked the policy and schedule setting, evrythings seems to be fine as it only happened for one policy. But need to know that if a schedule misses, then is there a way to generate alert from opscenter for skipped schedule.
