Hi @litchick10 ,

Can you try setTimeout - as it waits a short moment so ServiceNow can finish rendering the target list collector.

setTimeout(function() {
var ctrl = g_form.getControl('technology_cmdb_ci_business_app');
ctrl.focus();
}, 200);

Also change your "UI Type"  to "All" .

Thanks & Regards, 
Muhammad Iftikhar
