Vendor master outbound /CDHDR

Question

Hi,
i am workinng on creating a outbound file with all the ne wvendors and changes in existing vendors for a particular date.
for getting the new vendors for a particular date i am passing the date in lfb1 and retrieving the required data
but for the changes made to the existing vendors i am using table cdhdr and cdpos,but cannot figure out the logic to proceed further as everytime i change a particular vendor there is entry created for it in cdhdr and the number of chanegs done are captured in cdpos,suppose i changed trading partner and recon account vendor xyz a entry will be created in CDHDR ,now again if i change the same vendor xyz than there will be another entry created in cdhdr.
if sum1 have worked on the simiral requirement than plz help ,if u have any code than it will be gr8
plese reply its a bt urgent.
thanks in advance,
Warm regards,

Select entries from table CDHDR where the changed object
class is MATERIAL and date is equal with the given date.
  select OBJECTID CHANGENR
    from CDHDR
    into corresponding fields of table IT_CDHDR
    where OBJECTCLAS = 'MATERIAL'
    and UDATE = P_DATE.
  if SY-SUBRC eq 0.
Get change relevant fields from table ZLL_MATDL_CHG.
    select *
      into table LT_ZLL_MATDL_CHG
      from ZLL_MATDL_CHG.
    loop at LT_ZLL_MATDL_CHG into LS_ZLL_MATDL_CHG.
      R_TABNAME-LOW = LS_ZLL_MATDL_CHG-TABNAME.
      R_TABNAME-SIGN = 'I'.
      R_TABNAME-OPTION = 'EQ'.
      append R_TABNAME.
      R_FNAME-LOW = LS_ZLL_MATDL_CHG-FNAME.
      R_FNAME-SIGN = 'I'.
      R_FNAME-OPTION = 'EQ'.
      append R_FNAME.
    endloop.
   loop at IT_CDHDR into IS_CDHDR.
   loop at LT_ZLL_MATDL_CHG into LS_ZLL_MATDL_CHG.
MAIN SELECT INCLUDING ALL THE CHANGED FIELDS FOR ALL TABLES BOTH
INSERT AND UPDATE
    select OBJECTID CHANGENR TABNAME TABKEY FNAME CHNGIND
      from CDPOS appending corresponding fields of table IT_CDPOS
      for all entries in IT_CDHDR
    where OBJECTCLAS eq 'MATERIAL' and
            OBJECTID eq IT_CDHDR-OBJECTID and
            CHANGENR eq IT_CDHDR-CHANGENR and
             TABNAME eq LS_ZLL_MATDL_CHG-TABNAME and
               FNAME eq LS_ZLL_MATDL_CHG-FNAME and
           ( CHNGIND eq 'I' or
             CHNGIND eq 'U' ).
