السلام عليكم....
In oracle forms10g we don't have the property (Fixed Length),
so we have to check it programatically like this:

when-validate-item:

declare 
v_length number(10) := 15;
begin
if length(:my_item) > v_length then 
message('you can''t enter more than '||v_length||'  digits');
raise form_trigger_failure;
end;

you can change the v_length variable to any number you want .

good luck

thank for your response
but i want the alternative property of fixed length
i tried to read it in help but it was not clear exactly for me
