Problem when post G/L Document via BAPI_ACC_GL_POSTING_POST

Question

What I am doing is to post new G/L Accounting Document on each successfully paid transaction, each successfully reversed transaction, each rejected transaction for bank XXX, and each payment transaction for bank YYY in 3 Events respectively. And I am using the BAPI BAPI_ACC_GL_POSTING_POST to post.
but in the return table there are error messages, the sample code is as follows:
*& Get the OBJ_KEY of DOCUMENTHEADER *
get the current fiscal year
   l_fiscyear = sy-datum(4).
select the Number Range NO. out from T003
   select single numkr
      from t003
       into l_numkr
    where blart = 'SY'.
  if sy-subrc <> 0.
    message .
  endif.
call FM to get the Accounting Doc. No.
  call function 'NUMBER_GET_NEXT'
    exporting
       nr_range_nr = l_numkr
           object      = ‘RF_BELEG’
      subobject      = ‘HKHK’
          toyear      = l_fiscyear

        interval_overflow = 6
        buffer_overflow = 7
        others = 8.
if sy-subrc <> 0.

endif.
concatenate the Accountint Doc. No, the company code and the
fiscal year together as the OBJ_KEY
concatenate p_belnr ‘HKHK' l_fiscyear into lx_docheader-obj_key.
&--Get OBJ_KEY end--
get the OBJ_SYS

Hi
U haven't to transfer the reference data to the BAPI, the document number is picked up automatically:
* fill the structure parameter DOCUMENTHEADER of the BAPI
*    LX_DOCHEADER-OBJ_TYPE = 'BKPFF'.
    LX_DOCHEADER-USERNAME = SY-UNAME.
    LX_DOCHEADER-COMP_CODE = 'HKHK'.
*    LX_DOCHEADER-AC_DOC_NO = P_BELNR.
*    LX_DOCHEADER-FISC_YEAR = L_FISCYEAR.
    LX_DOCHEADER-DOC_DATE = P_DOC_DATE.
    LX_DOCHEADER-PSTNG_DATE = P_POST_DATE.
    LX_DOCHEADER-DOC_TYPE = ‘SY’.
* fill the table parameter ACCOUNTGL of the BAPI
    LWA_TABACCGL-ITEMNO_ACC = 1.
    LWA_TABACCGL-GL_ACCOUNT = ‘0000050107’ .
    LWA_TABACCGL-COMP_CODE = ‘HKHK’.
    LWA_TABACCGL-PSTNG_DATE = P_POST_DATE.
    LWA_TABACCGL-DOC_TYPE = ‘SY’.
*    LWA_TABACCGL-AC_DOC_NO = P_BELNR.
*    LWA_TABACCGL-FISC_YEAR = L_FISCYEAR.
    APPEND LWA_TABACCGL TO LI_TABACCGL.
    CLEAR LWA_TABACCGL.
    LWA_TABACCGL-ITEMNO_ACC = 2.
    LWA_TABACCGL-GL_ACCOUNT = ‘0000082910’.
    LWA_TABACCGL-COMP_CODE = ‘HKHK’.
    LWA_TABACCGL-PSTNG_DATE = P_POST_DATE.
    LWA_TABACCGL-DOC_TYPE = ‘SY’.
*    LWA_TABACCGL-AC_DOC_NO = P_BELNR.
*    LWA_TABACCGL-FISC_YEAR = L_FISCYEAR.
    LWA_TABACCGL-COSTCENTER = ‘0000011401’.
    APPEND LWA_TABACCGL TO LI_TABACCGL.
    CLEAR LWA_TABACCGL.
