Say which kinds of answer one of a form's controls offers — a crew, a technician or a supplier.
The whole list, because the control that sends it is a set of tick boxes. NULL offers all of them, which is what a form nobody has narrowed does; the empty list is refused, because a question nobody can answer is one you have stopped asking rather than one you have narrowed.
It binds the form that draws the control. Assigning a job from its own Assign action, from the dispatch board or through the routing engine is a separate deliberate act and is not narrowed by a form’s layout.
