Conversion of WBS Element.

Hello Experts,

I have an alv report in which i need to display WBS element. I tried to convert it  and pass it to alv but it still shows element in alv report as <<<PR00355453>>>.

I tried following code.

CALLFUNCTION'CONVERSION_EXIT_ABPSP_OUTPUT'

       EXPORTING

         input  = wa_zfi0200-wbs_element

       IMPORTING

         output = wa_zfi0200-wbs_element.

Help will be appreciated.

Regards,

PS
