Hi mconyers,
As far as I see it in ITMS 7.6 release, "Windows System Assessment Scan Summary" report uses stored procedure "spPMWindows_VulnerabilityAnalysisSummary" which queries these tables, views:
- Inv_AeX_AC_Identification
- CollectionMembership
- fnGetTrusteeScopedResourcesByScope
- vPMCore_GetAllRetiredMachines
- vComputerResourceEx
- ResourceUpdateSummary
According to quick checks, I see that "Last Inventory Received" column doesn't change date time after "Windows Assesment" scan execution on managed client in case if there were no new updates installed.
If managed client has new updates installed (or uninstalled old), then after "Windows Assesment" scan execution, "Last Inventory Received" field date time will be updated per this client.
Otherwise, this report shows when each managed endpoint has sent modified/changed inventory about installed patch updates.
Thanks,
IP.
