About Duplicate entries

Question

Hi experts,
In internal table i have many account numbers.
There are some duplicate entries. i have removed all the duplicates using the following code.
but i cannot remove all the duplicate entries.
certain scenarios i should have duplicate elements also in my output.
certain scenario i should remove the duplicates.
is there any way to remove few duplicate entries from internal table.
your furthur clarification i will send the code also.
DELETE ADJACENT DUPLICATES FROM itab_temp COMPARING RI_ACCT_NO .
  LOOP AT ITAB_temp.
  LOOP AT ITAB WHERE RI_ACCT_NO = ITAB_TEMP-RI_ACCT_NO.
    SUM_BETRH = SUM_BETRH + itab-BETRH.
    SUM_BETRW = SUM_BETRW + itab-BETRW.
ENDLOOP.
    ITAB_ALS = ITAB.
    ITAB_ALS-BETRH = SUM_BETRH.
    ITAB_ALS-BETRW = SUM_BETRW.
      APPEND ITAB_ALS.
    CLEAR: SUM_BETRH, SUM_BETRW, ITAB_ALS.
  ENDLOOP.
if u know pls send me documents to

its very urgent.
Thank you in advance.

Hi
You have add the following statement before the delete duplicate statement
SORT itab_temp BY RI_ACCT_NO.
DELETE ADJACENT DUPLICATES FROM itab_temp COMPARING RI_ACCT_NO .
I think now it will work. Otherwise some problem internal table fields.
Moreover this code not efficient.  You are using nested loops, it is performance killer.  Instead you can use for all entries.  Already u have data in ITAB_TEMP.
Select f1 f2... from XTABLE into table ITAB for all entries in ITAB_TEMP where RI_ACCT_NO = ITAB_TEMP-RI_ACCT_NO .
then u can add addition logic by using one loop and endloop.
