Removing states with client scripts

Next, make the option unavailable in the State choice list. While the Business Rule will abort any update if the Approval field isn't set correctly, it's nice to stop users getting confused and thinking they can set it themselves.

1. Navigate to System Definition > Client Scripts, and click New. Fill out the form with the following data, and Save.
   • Name: Remove External Repair state
   • Table: Maintenance [x_hotel_maintenance]
   • Type: onLoad
   • Script:

function onLoad() {
if (g_form.getValue('state') != '10')
g_form.removeOption('state', 10);
}
