Doubt in AT END OF...ENDAT statement...

Question

Hi,
I am retrieving the data from E071 table into an internal table "it_e071" ; and sorting it according to obj_name and trkorr fields.
Now, the sorted data in it_e071 table is of the format:
TRKORR   AS4POS     PGMID  OBJECT OBJ_NAME
X1            -                   -           -             ZOBJ1
X2            -                   -           -             ZOBJ1
X3            -                   -           -             ZOBJ1
Y1            -                   -           -             ZOBJ2
Y2            -                   -           -             ZOBJ2
Y3            -                   -           -             ZOBJ2
Y4            -                   -           -             ZOBJ2
Z1            -                   -           -             ZOBJ3
Z2            -                   -           -             ZOBJ3
Now, I want only the last record for each OBJ_NAME to be populated in another internal table "it_sfdet". So, for the above example "it_sfdet" should be:
TRKORR   AS4POS     PGMID  OBJECT OBJ_NAME
X3            -                   -           -             ZOBJ1
Y4            -                   -           -             ZOBJ2
Z2            -                   -           -             ZOBJ3
For this, I am using 'AT END OF' statement as in the following code:
    SORT it_e071 BY obj_name trkorr.
    LOOP AT it_e071 INTO wa_e071.
      AT END OF obj_name.
        wa_sfdet-trkorr = wa_e071-trkorr.
        wa_sfdet-sfname = wa_e071-obj_name.
        APPEND wa_sfdet TO it_sfdet.
      ENDAT.
    ENDLOOP.
However, at the end, the internal table "it_sfdet" is getting all the values of "it_e071" table. I want only the last record for each OBJ_NAME. The table E071 has TRKORR and AS4POS as the primary keys. Could you please tell me what exactly is wrong with the above code or suggest me any other way of achieving this.
Thanks,
Vishal.

Hi, Vishal Saxena
Please test the following Sample Code and don't use AT END OF ... ENDAT if you don't want OBJ_NAME Field as First Field of your Internal Table.
TYPES:  BEGIN OF ty_test_sdn,
  f1(3),
  f2(3),
  f3(3),
  END OF ty_test_sdn.
DATA: it_test_sdn TYPE STANDARD TABLE OF ty_test_sdn WITH HEADER LINE,
      wa_test_sdn LIKE LINE OF it_test_sdn,
      count TYPE i.
it_test_sdn-f1 = 'AAA'. it_test_sdn-f2 = 'AAA'. it_test_sdn-f3 = 'AAA'. APPEND it_test_sdn.
it_test_sdn-f1 = 'BBB'. it_test_sdn-f2 = 'DDD'. it_test_sdn-f3 = 'ZZZ'. APPEND it_test_sdn.
it_test_sdn-f1 = 'CCC'. it_test_sdn-f2 = 'BBB'. it_test_sdn-f3 = 'BBB'. APPEND it_test_sdn.
it_test_sdn-f1 = 'BBB'. it_test_sdn-f2 = 'AAA'. it_test_sdn-f3 = 'AAA'. APPEND it_test_sdn.
it_test_sdn-f1 = 'DDD'. it_test_sdn-f2 = 'SSS'. it_test_sdn-f3 = 'AAA'. APPEND it_test_sdn.
SORT it_test_sdn BY f3.
LOOP AT it_test_sdn.
  IF sy-tabix <> 1 AND it_test_sdn-f3 <> wa_test_sdn-f3.
    WRITE: / 'End of ', wa_test_sdn-f3, ' Number of Records were = ', count.
    CLEAR: count.
  ENDIF.
  ADD 1 TO count.
  MOVE-CORRESPONDING it_test_sdn TO wa_test_sdn.
ENDLOOP.
  WRITE: / 'End of ', wa_test_sdn-f3, ' Number of Records were = ', count.
Hope above Code will help you to solve out your Problem,
Please Reply if any Issue,
