VI Job to Update Auto-LogOff for users

SOLVED

We want to efficiently set all but a few users to have their AutoLogoff set to "Y" and have a 60 minute Inactivity Timer. So I'm trying to run a VI Job to update the SY_User table to update the following fields: AutoLogoff, InactivityTime and UserKey (just running replace with the existing UserKey) and I've gotten this error: "HS Record Invalid or Write Failed. Invalid User Logon."

I must be missing something here, unless this table isn't able to be updated in this way? Would it be more efficient to update the table directly via SQL?
