This is what you might do: basically, you don't want to "disable" current canvas, but change focus to another one (which is, actually, an item in another block that is located on a different canvas). Therefore, KEY-LISTVAL trigger (or, if you are opening a LoV by pushing a button, WHEN-BUTTON-PRESSED) might look like this:
go_item('dept.deptno');
list_values;
if :dept.deptno is null then
go_item('emp.empno');
end if;
In other words: if you don't select DEPTNO from list of values, :DEPT.DEPTNO item will remain empty, IF will evaluate to TRUE and you'll GO_ITEM (to another block on another canvas).
