types: begin of ty_mseg,
        matnr like mseg-matnr,
        werks like mseg-werks,
        ebeln like mseg-ebeln,
       end of ty_mseg.
data: wa_mseg       type ty_mseg,
      charg         type charg_d,
      mat_doc(10)   type c,
      year(4)       type c,
      item(4)       type c.
mat_doc = nast-objky(10).
year    = nast-objky+10(4).
item    = nast-objky+14(4).
select single * into corresponding fields of wa_mseg from mseg
where mblnr = mat_doc
   and mjahr = year
   and zeile = item.
select single charg into charg from mcha
where charg = wa_mseg-ebeln.
if sy-subrc <> 0.
  PERFORM OPEN_GROUP.

  perform bdc_field       using 'BDC_OKCODE'
                                '=ENTR'.
  perform bdc_field       using 'DFBATCH-MATNR'

Hi,
are you passign single screen? because in your code the screnn numbers are same(1000), if so, just comment these line and do..
perform bdc_dynpro using 'SAPLCHRG' '1000'.
perform bdc_field using 'BDC_OKCODE' '=ENTR'.
this might works you,
if not just give us the code, and the error messages,
Regards
