I'm not sure that's entirely accurate anymore. ABAP was adjusted some time ago to return EXPORTING, TABLES and CHANGING parameters in FMs or ABAP Class Methods <STRONG>even</STRONG> if you raise an exception.<BR>
<BR>
We have several examples of where an Exception is thrown and we can still trust the value of an Exporting 'Error' flag or Application Log instance as well.<BR>
<BR>
The flaw highlighted by Robert I think is buried in the way the value being received is being bound (or not) into the Method container.<BR>
