I don't know; but you may trap the exception once it is raised. Use the ON-ERROR trigger and FRM-40108 error code.

When ever you issue call form or new form then if the file is not there ON-ERROR message generates an error and in this way you can trap this event.

Cannot trap this event in On-Error trigger. Because i am calling this fmx through Menu . There is no ON-Error Trigger in menu module.
Is any other method to check whether exists or not?

Can you issue a 'host' command from a menu? If yes, then run a batch file to test if the 'fmx' exists. But why worry? If it doesn't exist the system will tell you.

Maybe you can use something like this to trap error in your menu

  open_form(p_module, ACTIVATE, SESSION, NO_SHARE_LIBRARY_DATA, pl_id);
  IF NOT form_success THEN
    message('Unable to call module');
    raise form_trigger_failure;
  END IF;

If the file does not  exists , system will give the error message to User. 
But here my requirement is  if the given fmx is not exists then  i need to call another fmx . 
Mr.Kaeluan gave me the solution to met the requirement.
