Unless it is an error - i.e. you don't expect it to come back empty - it is bad programming practice to use exceptions to control program flow.

Why not use IF mytab IS INITIAL instead?

In any case, you'll have to use that. With your example, the method oref->fin will need some code like:

IF mytab IS INITIAL.
  RAISE my_exception.
ENDIF.
