Altiris table & attribute name for "last configuration change" of Altiris Agent

Hi,

Please hep me to create a dynamic report for getting "Last Configuration Change" date for each Altiris agent. I saw an article that mentioned [StartTime] attribute of "Evt_NS_Client_Config_Request" table will provide [Last Configuration Request] date. Please let me know the table & attribute for "Last Configuration Change" date.

Thanks,

Kapil
