Hi Mittal -
BADI - ME_PROCESS_REQ_CUST , in the method PROCESS_ITEM is correct.
Follow the below code to get the GL data
DATA :   li_items TYPE mmpur_accounting_list,
             lw_items TYPE mmpur_accounting_type,
             lw_exkn  TYPE exkn.
   IF im_item IS NOT INITIAL.
   CALL METHOD im_item->if_acct_container_mm~get_items
      RECEIVING
        re_items = li_items.
IF NOT LI_ITEMS is initial.
    LOOP AT li_items INTO lw_items.
      CALL METHOD lw_items-model->get_exkn
        RECEIVING
          re_exkn = lw_exkn.
* Check the value of GL with lw-exkn-sakto to validate it
    ENDLOOP.
ENDIF.
   ENDIF.
