alerts are not working for adapter engine failures

Hi mates,

I am working on SAP PI7.3 dual stack. I have configured Message based alerting(Not CBMA). I have used the container elements SXMS_TO_ADAPTER_TYPE,SXMS_TO_ADAPTER_ERRT as well.  in NWA.. i have set the parameters  Alerting.isActive to true and Alerting.Target to 0. .But don't know why the alerts are not coming. But for Integration engine failures i am receiving alerts.

Please let me know if i have missed out some thing.

thanks in advance.

Regards,

Loordh.
