Alert Mechanism in NW BPM

Hello Experts,

I am using a  BPM scenario in which operational mapping is being called in NW BPM.

I want to set up an alert mechanism wherein an alert should be triggered to certain contacts(email ID's) if the mapping fails inside BPM.

Please share your views if the same can be achieved inside NW BPM and how.

Please let me know in case of any detail required from my end.

Thanks in Advance.

Regards,

Shubham
