Retirval problem for the old-new values from cdhdr,cdpos

Question

hi all.
i want to get the old and new values from cdhdr and cdpos table but not getting the output as the if condition of read statement" if i_cdhdr-objectid = itemp-kunnr." is not getting executed.what could be the mistake and how can i resolve.plz suggest
loop at it_knb1.
itemp-kunnr = it_knb1-kunnr.
itemp-kunnr1 = it_knb1-kunnr.
append itemp.
endloop.
if not itemp[] is initial.
select * from cdhdr
into table i_cdhdr
for all entries in itemp
where OBJECTCLAS = 'DEBI'
and   OBJECTID   = itemp-kunnr
and  tcode      = 'VD02'.
select * from cdhdr
appending table i_cdhdr
for all entries in itemp
where OBJECTCLAS = 'DEBI'
and   OBJECTID   = itemp-kunnr
and   tcode      = 'XD02'.
endif.
if not i_cdhdr[]  is initial.
select * from cdpos into table i_cdpos
for all entries in i_cdhdr
where OBJECTCLAS = i_cdhdr-OBJECTCLAS
and   OBJECTID   = i_cdhdr-OBJECTID
and   TABNAME    = 'KNVV'
and   (  FNAME = 'ZTERM' ).
endif.
loop at it_knb1 where kunnr = it_kna1-kunnr.
read table itemp with key kunnr1  = it_knb1-kunnr.
if sy-subrc = 0.
loop at i_cdhdr.
if i_cdhdr-objectid = itemp-kunnr.
it_final-username = i_cdhdr-username.
clear i_cdpos.
read table i_cdpos with key OBJECTCLAS = i_cdhdr-OBJECTCLAS
                             OBJECTID   = i_cdhdr-OBJECTID
                             FNAME = 'ZTERM'.
if sy-subrc = 0.
    it_final-zterm_old  = i_cdpos-value_old.
    it_final-zterm_new  = i_cdpos-value_new.
  endif.
endif.
endloop.
endif.
endloop.

Hi Tanisha,
BEtter to loop everything cdhdr and CDPOS
U can do one thing.
Use CHANGEDOCUMENT_READ_HEDAER to get the data from CDHDR.
SUE FM CHANGEDOCUMENT_READ_POSTIONS.
to get the data from the each change number.
then u can retrieve the data as u want.
This will avoid confusion.
U can get the correct data.
Thanks
