Hi All,

How to copy the duplicates from sorted internal table values into other internal table.

Thanks,

loop at itab.
  clear flag.
  at new matnr.
    flag = 'X'.
  endat.
  if flag ne 'X'.
  move-corresponding itab to itab1.
  append itab1.
  endif.
  
endloop.

where matnr is the duplicate entry in itab.

Hi,

I think there is no direct command. You will have to build ur own logic.

>> First take a copy of the original internal table

>> Then SORT the table and do a adjacent duplicate

>> Now you have 2 tables one with original data and second with unique data.

>> Compare the two tables using a loop.

itab_1[] = itab[].

SORT ITAB bY F1 F2.

DELETE ADJACENT DUPLICATES FROM ITAB.

Loop at itab_1.

READ TABLE ITAB with key ITAB = itab_1.

IF sy-subrc eq 0.

CONTINUE.

ELSE.

DELETE.

ENDIF.

endloop.

Cheers

Do you have any example code.

Hello Vijayendra,

READ TABLE ITAB with key ITAB = itab_1.

This stmt is not working.

Thanks,

Venkat

change it to

READ TABLE ITAB with key ITAB-fld1 = itab_1-fld1
                         ITAB-fld2 = itab_1-fld2.

You can write the fields with key statement..eg

READ TABLE ITAB with KEY itab-f1 = itab_1-f1

itab-f2 = itab_1-f2....

etc

I dont think it can done via a single command..need to use the below logic.

sort itab.

loop at itab.

istab = itab.

at end of field.

move-corresponding istab to itab1.

append itab1.

endat.

endloop.

Hi,

try this code:

sort itab.

loop at itab.

at new fld1.

..

endat.

itabdup-fld1 = itab-fld1.

append itabdup.

clear itabdup.

end loop.

delete adjacent duplicates from itab comparing fld1.

reward if helpful,

Please see the following example. this program pulls out records only when they have a duplicate entry in the table. In this case, the record with GHI will be outputed.

report zrich_0001.


data: begin of itab occurs 0,
      f1 type c,
      f2 type c,
      f3 type c,
      end of itab.
data: begin of itabx occurs 0,
      f1 type c,
      f2 type c,
      f3 type c,
      end of itabx.
data: begin of itabo occurs 0,
      f1 type c,
      f2 type c,
      f3 type c,
      end of itabo.

data: counter type i.


itab = 'ABC'.  append itab.
itab = 'DEF'.  append itab.
itab = 'GHI'.  append itab.
itab = '123'.  append itab.
itab = '456'.  append itab.
itab = '789'.  append itab.
itab = 'GHI'.  append itab.


itabx[] = itab[].

sort itabx ascending.
sort itab ascending.
delete adjacent duplicates from itab.

loop at itab.

  clear counter.
  loop at itabx where f1 = itab-f1
                  and f2 = itab-f2
                  and f3 = itab-f3.
    counter = counter + 1.
  endloop.
  if counter > 1.
    move itab to itabo.
    append itabo.
  endif.

endloop.


* Output the record that had a duplicate entry
loop at itabo.
  write:/ itabo.
endloop.
