Attempts to enable SQL tracing from concurrent request form fails with error:
Function not available to this responsibility. Change Responsibilities or contact your System Administrator
Switch responsibility to "System Administrator". Navigate to System -> Profiles, and query for "%Diagnostics% ("Utilities : Diagnostics")". Once found the profile, change its value to "Yes". Restart web browser and try enabling SQL trace again.
