Change SF BBP_OUTPUT_COVER doesn´t work

Hi all !

I try to change standard body text of notifications . I create a Z copy from BBP_OUTPUT_COVER and a copy from BBP_OUT_EXCEPTION.

I assign ZBBP_OUT_EXCEPTION in badi BBP_OUTPUT_CHANGE_SF and it is working fine.

But if I try the same with  BBP_OUTPUT_COVER,

    IF cv_smartform = 'BBP_OUTPUT_COVER'.

  cv_smartform = 'ZBBP_OUTPUT_COVER'.

cv_smartform_mail = 'ZBBP_OUTPUT_COVER'.

*ENDIF.

besides that does not work, not even send the mail. I tried with  BBP_CHANGE_SF_BID, same results.

Any idea??

thanks!
