Alert is not generated for cancelled messages

Hi All,

We are facing an error for alert communication.

When our messages go directly to cancelled state alerts are not generated in SAP PI 7.4 single stack. If messages goes in system error them alerts are generated.

We have a SOAP to RFC synchronous scenario, if SAP system is not able to send response in a defined time , then message fail in SAP PI with time out error , which is right. But these messages directly fail with Cancelled status and alerts are not being triggered for these cancelled messages..

Please Suggest.

Thanks

Shivi
