<P>Hi all,</P>
<P> </P>
<P>I discovered where the evil is. In the old situation with BOR objects, the method has a return parameter (setting on the method). So the 'exceptions' are not exceptions but return values.</P>
<P> </P>
<P>Is there a possibility to use this with a Class method?</P>
<P> </P>
<P>Best regards,</P>

<P>Mike,</P>

<P>it does not realy need a statement to pass the value, does it?</P>
<P> </P>
<P>The export parameter is set by the normal ABAP statement:</P><FONT size=1>
<P>APPEND ls_amr TO amr_reject.</P></FONT>
<P>AMR_REJECT is set as exporting parameter.</P>

<BLOCKQUOTE type="cite">Jocelyn,<BR> <BR>I'm not sure that's entirely accurate anymore.
