You can do it, but not from the UFT UI. It requires a registry setting change.
Make sure you close UFT/QTP/ST before doing this, and you need full admin rights.
1. Open the registry editor. (Start > Run > type ''regedit'' > ''Ok'')
2. Go to registry key HKEY_LOCAL_MACHINESOFTWAREMercury InteractiveQuickTest ProfessionalLoggerMediaReport (or for 64 bit machines its in HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMercury InteractiveQuickTest ProfessionalLoggerMediaReport)
3. Find the ''Active'' item and change the value to 0. This will make it so UFT does not generate results.
To turn it back on, simply change the value back to 1.
You can do the same with with Service Test at this registry key:
HKEY_LOCAL_MACHINESOFTWAREHewlett-PackardHP Service TestLoggerMediaReport
(or for 64 bit machines its in HKEY_LOCAL_MACHINESOFTWAREWow6432NodeHewlett-PackardHP Service TestLoggerMediaReport)
