Delete adjacent duplicates how to use in the below select statement

Question

hi i have a problem
i am suing the below select statement
SELECT    a~extno
          a~guid_lclic       " for next select
          e~ctsim
          e~ctsex
*revised spec 3rd
          f~guid_pobj
          f~amnt_flt
          f~amcur
          f~guid_mobj
          e~srvll     "pk
          e~ctsty     "PK
          e~lgreg  "PK
  INTO TABLE gt_sagmeld
  FROM /SAPSLL/LCLIC  as a
  INNER JOIN /sapsll/tlegsv as e on elgreg = algreg
  inner join /sapsll/legcon as f on fguid_lclic = aguid_lclic   " for ccngn1 selection
  inner join /sapsll/corcts as g on gguid_pobj = fguid_pobj
                           where   a~extno in s_extno.
  sort gt_sagmeld by guid_lclic lgreg ctsty srvll GUID_POBJ GUID_MOBJ.
  delete adjacent duplicates from gt_sagmeld comparing guid_lclic lgreg ctsty srvll GUID_POBJ GUID_MOBJ .
now i am confused how to use delete adjacent dupliacate and on which fields
as first table /sal../lclic primary key is guid_lclic
and it is joined to table
legcon by guid_lclci ( not a primary key here)
legcon primary key is guid_legcon
and table 3 legsv by lgreg (pk here)
table 3 has tow more primary key srvll and ctsty also
NOW MY QUESTIO IS TAHT IS I USE ABOVE DELETE ADJACENT STATMENT IT FETCHES 20 LAKH RECORDS
I WANT TO REDUCE IS LET ME KNOW ON WHAT fields i need to use delete adjacen duplicates
or use comparing all fields?

hi sudha
if u see my select statement is contains four Primary keys
srvll
lgreg
ctsty
guid_lclic
but the next table connected to this table legcon is by guid_pobj and anothe table by guid_mobj
and if i take this gt_sagmeld to another temp table and i find abt 10 lakh uniques guid_pobj
similary 6 lakh guid_mobj so the next slect is hanpering because of this
not COMING TO OUR POINT IF I SORT ONLY BY OUR PRIMARY KEYS NOT TAKING INTO ACCOUNT TEH GUID_POBJ AND GUID_MOBJ
THE ENTRIES ARE VERY LESS BUT IF I TAKE INOT ACCCOUNT IN GT_SAGMELD THE ENTRIES ARE ABT 20 LAKH
SO I AM NOT SURE WHETHER TO TAKNE GUID_POBJ AND GUID_MOBJ INOT ACCOUNT FOR DELECTING ADJACENT DUPLICATES?
HENCE THE QUESTION OF ON WHICH FIRLD DELETE OR COMPARING ALL FIELDS I USE?
