I think that you should return a proper error code.

   return Acknowledge (Messages.S200)

And test using:

   If Status_Code (Result) = Messages.S200 then
      ...

Empty, as described in the comment, is mainly there to be used by the chain
callbacks in the dispatchers and I quote "should not be used by users." :)

Why don't you want to use Acknowledge ?
