Deleting Duplicate entries from Internal tbale

Hi All,
I have used this code to delete duplicate entries from an internal table.
DELETE ADJACENT DUPLICATES FROM IT_KOSTL COMPARING KOSTL hours.
After this statment, still the internal table will remain with a duplicate row.
Earlier table content before the delete statement:
Lno KOSTL                PRCTR                       hours                      hours1
1    2081010205     0000208101                 5525.000          1574.500
2    2081010105     0000208101       105162.000     73854.750
3    2081010105     0000208101       105162.000     73854.750
4    2081010205     0000208101        5525.000     1574.500
The Table gets modified after execution of DELETE statement as follows.
Lno KOSTL                PRCTR                       hours                      hours1
1    2081010205     0000208101                 5525.000          1574.500
2    2081010105     0000208101       105162.000     73854.750
3    2081010205     0000208101        5525.000     1574.500
Why the line 3 is still present in the table?
I hope as per that syntax, this line too should get delete.... Is it right?
Basically i would like to delete both line 3 and line 4 from....
How to resolve this issue?
Please help me out....
Regards
Pavan
What might be the reason?

Let me answer you all doubts.
Why the line 3 is still present in the table?
Actually it's not 3rd line, it's 2nd line.3rd line were deleted.
when delete adjecent duplicates trigger than it would delete lower line(3rd in your case) not upper line.
I hope as per that syntax, this line too should get delete.... Is it right?
NO.

To delete duplicate records from internal table

hi friends,
i have to delete records from internal table based on following criterion.
total fields are 7.
out of which if 4 fields are same and 5th field is different,then both records must be deleted.
in case all five fields are same,the program should do nothing.
for example.
if there are 3 records as follows
a1 b1 c1 d1 e1 f g
a1 b1 c1 d1 e2 w r
a1 b1 c1 d1 e1 j l
then first two records should be deleted as four fields are same but fifth(e) field differs.
but third record should remain as it is evenif first five fields are same for first and third record.
values of last two fields need not to be consider for deleting the records.

LOOP AT ITAB.
V_FILED5 = ITAB-F5. "to compare later
V_TABIX = SY-TABIX. "used to delete if condition not matches
READ TABLE ITAB WITH KEY F1 = ITAB-F1
 F2 = ITAB-F2
 F3 = ITAB-F3
 F4 = ITAB-F4.
IF SY-SUBRC = 0.
 IF ITAB-F5 <> V_FIELD5.
*--both the records to be deleted,as Field5 is different.
 DELETE ITAB INDEX SY-TABIX. "deletes that record
 DELETE ITAB INDEX V_TABIX. "deletes the current record
 ENDIF.
ENDIF.
ENDLOOP.

Deleting entry from internal table

Hi Experts,
i have the following internal table:
data : it_result1 TYPE crmt_object_guid_tab
and work area
data : wa_result1 type crmt_object_guid.
i have to delete a guid from internal table based on some condition.
loop at it_resul1 into wa_result1
if lv_priority eq priority.
delete this entry from internal table.
endif.
endloop..
i tried using delete table it_result with table key CRMT_OBJECT_GUID = wa_result. but this is giving syntax error.
what should be done to delete the entry?
Thanks and regards
Shilpi

Hi
Check Syntax for DELETE operator on pressing F1
1. DELETE itab.
2. DELETE TABLE itab WITH TABLE KEY k1 = v1 ... kn = vn.
3. DELETE TABLE itab [FROM wa].
4. DELETE itab INDEX idx.
5. DELETE itab FROM idx1 TO idx2.
6. DELETE itab WHERE logexp.
7. DELETE ADJACENT DUPLICATES FROM itab.
delete table it_result with table key CRMT_OBJECT_GUID = wa_result
this is wrong
delete it_result where CRMT_OBJECT_GUID = wa_result

Pls help me with the appropriate logic,its urgent.

Hi,
Deleting Adjacent Duplicate Entries
To delete adjacent duplicate entries use the following statement:
DELETE ADJACENT DUPLICATE ENTRIES FROM <itab>
[COMPARING <f1> <f2> ...
|ALL FIELDS].
The system deletes all adjacent duplicate entries from the internal table <itab>. Entries are
duplicate if they fulfill one of the following compare criteria:
Without the COMPARING addition, the contents of the key fields of the table must be
identical in both lines.
If you use the addition COMPARING <f1> <f2> ... the contents of the specified fields <f1>
<f2> ... must be identical in both lines. You can also specify a field <fi> dynamically as
the contents of a field <ni> in the form (<ni>). If <ni> is empty when the statement is
executed, it is ignored. You can restrict the search to partial fields by
specifying offset and length.
If you use the addition COMPARING ALL FIELDS the contents of all fields of both lines
must be identical.
You can use this statement to delete all duplicate entries from an internal table if the table is
sorted by the specified compare criterion.
If at least one line is deleted, the system sets SY-SUBRC to 0, otherwise to 4.
Examples
DATA: BEGIN OF LINE,
COL1 TYPE I,
COL2 TYPE I,
END OF LINE.
DATA ITAB LIKE HASHED TABLE OF LINE WITH UNIQUE KEY COL1.
DO 4 TIMES.
LINE-COL1 = SY-INDEX.
LINE-COL2 = SY-INDEX ** 2.
INSERT LINE INTO TABLE ITAB.
ENDDO.
LINE-COL1 = 1.
DELETE TABLE ITAB: FROM LINE,
WITH TABLE KEY COL1 = 3.
LOOP AT ITAB INTO LINE.
WRITE: / LINE-COL1, LINE-COL2.
ENDLOOP.
The output is:
2 4
4 16
The program fills a hashed table with a list of square numbers. The DELETE
statement delete the lines from the table where the key field COL1 has the contents 1 or 3.

pls help me with logic.
thank you for helping me

Hello Guys,
It is not advisable to delete the entries from the internal table you are looping upon. See this thread: [Sy-tabix in loop : Doubt|Sy-tabix in loop : Doubt]
And to answer the OP's question select data into some local internal table & based on the condition populate your final table. Creating a local table of the same type as the final table will not create too much performance overhead

Suhas

How to delete duplicate entries in match code

I want to delete duplicate entries in match code.

If you go down the search exit route, using function module F4_IF_SHLP_EXAMPLE or function module F4_IF_SHLP_EXIT as a template you want it where callcontrol-step = 'DISP'. You would sort the table: SORT RECORD_TAB BY STRING and then delete adjacent duplicates. If this does not wok because of the fields you have in your search help, you will need to select the data into another internal table and match the relevant entries from your internal table with the relevant position in field STRING of RECORD_TAB. The positions in STRING will be as per the order of the parameters you have defined in the search help.
Hope this helps.
Regards
Larissa

How to check duplicate entries in internal table??

Dear Friends,

Hi,
After storing the data into internal table say ITAb, move the data into another internal table.
t_dup[] = itab[].
LOOP AT itab.
    count1 = count1 + 1.
    itab-count1 = count1.
    MODIFY itab.
ENDLOOP.
LOOP AT t_dup.
    count2 = count2 + 1.
    t_dup-count2 = count2.
    MODIFY t_dup.
ENDLOOP.
DELETE ADJACENT DUPLICATES FROM itab.
LOOP AT t_dup.
    record_dup = 'N'.
    READ TABLE itab WITH KEY count1 = t_dup-count2.
    IF sy-subrc = 0.
      record_dup = 'Y'.
    ENDIF.
    IF record_dup NE 'Y'.
      t_dup-message = 'DUPLICATE ENTRY'.
      t_dup-flag = 1.
      MODIFY t_dup.
    ENDIF.
ENDLOOP.
Use this sample code.
Reward pts if it is helpfull.

Delete duplicate entries

Please go to the following website:-

Deleting Adjacent Duplicate Entries
To delete adjacent duplicate entries use the following statement:
DELETE ADJACENT DUPLICATE ENTRIES FROM <itab>
 [COMPARING <f1> <f 2> ...
 |ALL FIELDS].
Then please go to the last example where the code is written as :-
DELETE ADJACENT DUPLICATES FROM ITAB COMPARING ALL FIELDS.
IS THIS CORRECT ?

Hi learner,
Deleting a sequence of lines
DO 101 TIMES.
DELETE TAB_DEST INDEX 450.
ENDDO.
DELETE TAB_DEST FROM 450 TO 550.
Deleting a set of lines
LOOP AT TAB_DEST
WHERE K = KVAL.
DELETE TAB_DEST.
ENDLOOP
DELETE TAB_DEST WHERE K = KVAL.
DELETE ADJACENT DUPLICATES
As with the ORDER BY clause it could be better to avoid using SELECT DISTINCT, if some of the fields are not part of an index. Instead use ABAP SORT + DELETE ADJACENT DUPLICATES on an internal table, to delete duplicate rows.
 LOOP AT TAB1.
 READ TABLE TAB2 INDEX SY-TABIX.
 IF TAB1 <> TAB2.
 TAB_DIFFERENT = 'X'. EXIT.
 ENDIF.
ENDLOOP.
ENDIF.
IF TAB_DIFFERENT = SPACE. " ...
ENDIF.
IF TAB1[] = TAB2[]. " ...
ENDIF.

How to delete duplicate entries in address book

Is there an easy way to delete duplicate entries in Address Book?

I have an iPhone where I create new contact details and a MB Air running OX X 10.7.3
In Address Book I see duplicate entries across the whole book. The other day I was traveling without my MB and needed to urgently reach someone who's number I knew was in my iPhone contact list for sure but searched and search and couldn't find it.
Turns out that when I had been going through the Adress Book on the MB Air trying to eliminate some of the duplicates I had chosed --without even knowing it or realzing it-- the card that I guess sync with my iPhone. It was gone. Sure enough, when I got back and looked it up on the MB Air it was still there not syncing to my iPhone.
I have used Address Book / Card / Look for Duplicates ...
I have also followed the Help suggesting and pressed Control / select to highlight two duplicate cards and even though the First / Last / Company / phone numbers / etc. are all the same I get the message: "The cards could not be merged because they came from different accounts."
I have checked with guys from the office who have the exact same problem with no idea how to solve the problem.
Is it that in order to use Address Book on both an iPhone and an OS X machine you've just got to be smarter, more sophisticated, more IT oriented?
Seems like a pretty easy thing not to be struggling with.
I should mention that I was a Mobile Me subscriber and now use iCloud which I'm sure has something to do with all of this.
But it seems pretty basic to me. If I have an Address Book it should synchronize between OX X and IOS.

Trick to remove duplicate entries from tables ?

hi.
i have 53tables which are having duplicate entries and names of all 53 tables r listed in top_t table ?
can any1 provide me solution to show and if possible ask for remove of those duplicates entries from each table if required ?
daily i am removing duplicates manually ....its too tedious now !
can any1 help me out ?

Well, I suppose if the duplication is such that
SELECT DISTINCT * FROM tablename;gives you the required result, then you could have a procedure that made a copy of the table, deleted/truncated the original, then inserted the distinct values back into it.
In 10g you could even use flashback to avoid the temp copy - but it also means you can't use TRUNCATE so whether it's any more efficient I'm not sure. But just for fun and since it's urgent:

Deleting duplicate entries

I have two tables (Accounts, and Accounts_LOAD). The _Load table is a daily feed.
For my first step, I need to delete all the duplicates from _Load that exist in Accounts.
How can I delete duplicate entries which exist in two tables..?

I think that the Merge will suffice. My apologies.
But, now (again, sorry) I have a couple questions on the merge.
Below is similar to what I would use and a few Q's on it....
line4: can u use multiple "on" ?
line5:For 'when matched' i only want to update fields from "_load" to "Accounts" that need to be updated. If they are the same, they would be ignored... is that possible...?
1 MERGE INTO accounts acc
2 USING (SELECT **ALLFIELDS**
3 WHERE SOMESTUFF=STUFFS) STF
4 ON (ACC.ID_USER = STF.ID_USER) AND (ACC.SYSTEM_ID = STF.SYSTEM_ID)
5 WHEN MATCHED THEN UPDATE SET acc.bonus = D.bonus + S.salary*.01
6 DELETE WHERE (S.salary > 8000)
7 WHEN NOT MATCHED THEN INSERT (D.employee_id, D.bonus)
8 VALUES (S.employee_id, S.salary*0.1)
9 WHERE (S.salary <= 8000);

Deleting duplicate entries in iCal?

How do I delete duplicate entries in iCal (identical entries on the same date)?

Todd,
I suspected a more serious problem because the answer was too easy.
Thousands of duplicate entries...Is this what happened?
According to, Mac OS X 10.4: Stay away from the SyncServices folder: As if it were a swarm of bees, you should stay away from the SyncServices folder in Mac OS X 10.4. Removing or modifying anything in it—or in subfolders within it—may cause unexpected issues. (This folder is located in your Application Support folder, in your Library folder, in your Home folder.)
Deleting or modifying things in the SyncServices folder may cause unexpected results such as:
• Duplicate contacts in Address Book or appointments in iCal.
• Data loss in Address Book or iCal.
Important: Any lost or duplicate data could propagate to other devices and computers via iSync and .Mac sync. This means data could be lost on other computers.If that is your problem, I suspect that without a backup, duplicate entry deletion will at best be tedious, and at worst fraught with frustration. You may be better off starting from scratch.

Please help me with easiest possible way ..
Dilip Patil..

How do you determine which one out of duplicate to be kept? As per output it doesnt follow any pattern
so it may be this
--DELETE t
SELECT *
FROM
SELECT ROW_NUMBER() OVER (PARTITION BY FILE_ID,Quarter_Date ORDER BY FILE_ID) AS Rn,*
FROM FileStageLog
)t
WHERE Rn >1
Run the select above to see records to be removed and once happy uncomment the delete, comment the select * and run the query to do the delete
If it doesnt give expected records, explain on what basis you want to identify records to be deleted
