Internal tables issue

[ashok_2329]

I have an internal table with 300 records. How can i delete every 3rd record of my internal table

You can look at all possible operations on internal tables here: https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abentable_processing_...

Concerning the logic of deleting lines number 3, number 6, number 9, etc., I guess you won't have any difficulty knowing the statements to process the internal tables.

Hi,

have you tried this

loop at it_data into data(wa_data).
  check sy-tabix mod 3 = 0.
  delete it_data.
endloop.

Hi,

I was trayed this but it will delete every record after 1 and 2.

I am getting only first two records in my output after use this statement.

The problem is that after the deletion sy-tabix will always be three.

[ThorstenHoefer]

Can you add your own variable like

i_cnt

loop at it_data into data(wa_data).
  add 1 to i_cnt.
  check i_cnt mod 3 = 0.
  delete it_data.
endloop.

Hi ashok_2329,

Since ABAP Release 7.87/7.55, SAP BTP ABAP Environment 2202, there's the addition STEP, which you can use for defining a step size. For example:

DELETE itab STEP 3.

Link to documentation (https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abapdelete_itab_lines...) and blog post (https://blogs.sap.com/2022/07/04/reverse-loop-finally-possible-with-step-addition-for-abap-internal-...).

Best regards,

Lena

I haven't tested this. But this could work:

DATA(output) =
      value #(
        FOR  i = 1 THEN i + 3  WHILE i <= lines( itab )
        ( itab[ i ] )  ).


output =
      value #(
        base output
        FOR  i = 2 THEN i + 3  WHILE i <= lines( itab )
        ( itab[ i ] )  ).

Check the below.

Data: lv_index type sy-tabix.
loop at it_data assigning field symbol(<lfs_data>).
lv_index = sy-tabix.
  check lv_index mod 3 = 0.
   clear <lfs_data>-fieldname.
endloop.
delete it_data where fieldname is initial.<br>
