Search Appliance SBE
When set to Y, no walk will launch for this profile for any
reason (manually run, schedule, etc). Note that even if set to N, walks
may still be globally disabled if the System Wide Setting
Disable Starting All Walks is set.
This can be useful with profiles that should be dataload-only, or for profiles that want to guarantee their content won't change.
Walks that are already running when this is set will finish normally.
