SAM Integration with ticketing system

Hi All

We are able to integrate SAM with Remedy system and we are able to capture Incident ID as a response from Remedy in SAM. Now we need to update this incident number in SAM active alert console.

For this we have created a alert custom property  called "ticketid" and we are able to see this column in active alerts

I need to update incident number to this alert custom property space. For this I need to know what is that it unique thing that I can capture in an alert, so that I can use that as a reference to update this field using swql. I have worked on HP OM, there we have " msg id" as a unique reference to update the alerts. I'm looking for something similar alert uniqueness in SAM

Thanks
