Hi Nanda,
just to be a little constructive.
The documentation clearly lists all available variables that are available for a given object; in this case, for EmailAlertGateways, the following are supported:
- ${address} - the addressee's address
- ${messageTitle} - the title of the message
- ${subject} - the subject
- ${message} - the message
- ${alertSource} - the alert source that triggered the alert
- ${object} - the object that triggered the alert
As you can see, topLevelJobId is not part of the above list.
The easiest way to see which variables are available is by opening the overview, in this case Alerting > Email AlertGateways, and hitting F1.
Regards,
HP
