how to create collection to computers without LastHardwareScan and LastSoftwareScan

here you can change the data as you like for my Ex :
STATUS.LastHardwareScan, Getdate()) > 60  
LastSoftwareScan.LastScanDate, Getdate()) > 30

also if you want Hardware only you can delete


    and Datediff(DD,SMS_G_System_LastSoftwareScan.LastScanDate, Getdate()) > 30
