Methods for BAdI

Hi,

    I am trying to implement a BAdI J_3RFBS_ALL_BADI. There are two methods in it. IF_EX_J_3RIF_EX_FBS_ALL_BADI~MODIFY_OUTPUT. and  IF_EX_J_3RIF_EX_FBS_ALL_BADI~SET_FORM_DMEE_NAMES. I need help in writing code between these methods so that i get output of financial statement in English language than in Russian.
