Example implementation of BAdI BBP_ACCOUNT_CHECK_BADI ?

Hi,

I implemented BAdI BBP_ACCOUNT_CHECK_BADI with the following code:

***

DATA ls_exp_cobl TYPE bbpcobl_eci.

  exp_cobl = bbp_cobl.

  LOOP AT exp_cobl INTO ls_exp_cobl.

    IF ls_exp_cobl-costcenter IS NOT INITIAL.

      CLEAR ls_exp_cobl-func_area.

    ENDIF.

  ENDLOOP.

***

Has anybody implemented that BAdI and will the above work? We need to clear the functional area in order to ensure a new determination. We have issues with cost centers being changed ion the shopping cart and the functional area is not derived anew.

We face a similar issue with time sheets for service (ML81N). Any idea if this will help there, too?

Thanks
