Hi all,

In an internal table i have 5 fields.

My requirement is for the last record i have to delete entries only for 3 fields .

Ex: In itab

f1 f2 f3 f4 f5

12 18 19 20 24

09 24 32 25 26

25 26 28 29 30.

So for the last record i want to delete entries for f1 f2 f3(25 26 28) only i need f4 and f5(29 30) for display.

Please kindly help me.

Sai,

read itab into waTab index 3.

Clear: waTab-f1, waTab-f2,waTab-f3.

modify iTab from waTab index 3.

Thanks

Hi sai,

try this way.....


data last_record type i.
last_record = sy-dbcnt - 1.

  loop at itab into wa.
 
    if sy-tabix = last_record.

     *use clear

    endif.
  endloop.

hope this also helps you.

regards,

venu.

Hi,

to get the number of entries in the internal tab use:

DATA: rows_in_itab TYPE i.

DESCRIBE TABLE itab LINES rows_in_itab.

Then you can read the last row in the itab and modify the fields:

READ itab INTO wa INDEX rows_in_itab.

CLEAR: wa-f1, wa-f2, wa-f3.

MODIFY iTab FROM wa INDEX rows_in_itab.

Kind Regards

Mathias
