it_table operation

Former Member — Mon, 25 May 2009 10:00:13 GMT

hi all,

i have obtained certain data in an it_table. suppose it is in the following format.

TYPE DETAILS NUMBERGRP

A ABC 123

B VVV 555

C WNM 675

i want to delete duplicate entries. i am aware of the syntax 'Delete adjacent duplicates'. i dont want to retain even a single duplicate entry.

Basically, in this case i want to delete both entries which are duplicate i.e. the 1's with type 'A'.

Please help me with a the syntax which would help me do that.

Thanks in advance.

Regards,

Kaustubh

Hi,

For achiving this, you will have to write a loop.

SORT itab BY field1 field2 field3.
LOOP AT itab.
  IF ( lv_field1 = itab-field1 AND lv_field2 = itab-field2 AND lv_field3 = itab-field3 ).

    DELETE itab WHERE field1 = itab-field1 AND field2 = itab-field2 AND field3 = itab-field3.
    CLEAR: lv_field1, lv_field2, lv_field3.

  ELSE.
    CLEAR: lv_field1, lv_field2, lv_field3.
  ENDIF.
  lv_field1 = itab-field1.
  lv_field2 = itab-field2.
  lv_field3 = itab-field3.
ENDLOOP.

Hi,

use below statements

delete adjacent duplicates from it_ekpo comparing type

if required for all fields means use

delete adjacent duplicates from it_ekpo comparing all fields

Thanks,

Hi,

use the code given below this will solve your issue for sure...

DATA : w_index TYPE sy-tabix.
DATA w_count TYPE i.
LOOP AT it_table.
  w_index = sy-tabix.
  CLEAR w_count.
  LOOP AT it_table WHERE type = it_table-type AND details = it_table-details 
                                   AND numbergrp = it_table-numbergrp.
    ADD 1 TO w_count.
    IF w_count > 1.
      DELETE it_table WHERE type = it_table-type AND details = it_table-details 
                                    AND numbergrp = it_table-numbergrp.
      EXIT.
    ENDIF.
  ENDLOOP.
ENDLOOP.

Hi kaustubh,

You can try out this syntax:

DELETE ADJACENT DUPLICATE ENTRIES FROM <itab> [COMPARING... ].

Deletes adjacent duplicate entries, either by comparing the key fields or the comparison fields specified explicitly in the COMPARING addition.
