You can loop at the itab right.

loop at itab into wa_itab

logic

endloop.

or if you want to read

DESCRIBE TABLE itab lines count.

cnt = 1.

Do count times.

READ TABLE itab into wa_itab index count.

Logic you want...

cnt = cnt + 1.

ENDDO.

Hope this is what you want

Hi,

Use LOOP AT to read the records in the final internal table..

LOOP AT IT_FINAL..

ENDLOOP.

Thanks,

Naren

I don't understand what you need:

Read the records of internal table: use LOOP/ENDLOOP or READ TABLE statament:

LOOP AT ITAB.

ENDLOOP.

DO.

READ TABLE ITAB INDEX SY-INDEX.

IF SY-SUBRC <> 0. EXIT. ENDIF.

ENDDO.

You need to read a record using e record of the same table:

DATA: WA LIKE ITAB.

LOOP AT ITAB.

READ TABLE ITAB INTO WA WITH KEY ....

ENDLOOP.

use

loop at itab.

endloop.

a better way if you are sure that you need only specific data, then use 'where' along with the loop.

loop at itab where<condition>.

<code>

endloop.

Hi Max,

I have coded it like this but it is not working.

LOOP AT lt_final INTO lw_final.

READ TABLE lt_final INTO lw_final WITH KEY delnum = lw_final-delnum.

IF sy-subrc = 0.

can you tell me what is error in this.

Regards,

Venu.

You have to use another workarea:

DATA: LW_FINAL2 LIKE LW_FINAL.

LOOP AT lt_final INTO lw_final.

READ TABLE lt_final INTO lw_final2 WITH KEY delnum = lw_final-delnum.

IF sy-subrc = 0.

But you risk to obtein the same record, try this:

DATA: LW_FINAL2 LIKE LW_FINAL,

TABIX TYPE SY-TABIX.

LOOP AT lt_final INTO lw_final.

TABIX = SY-TABIX.

LOOP AT lt_final INTO lw_final2

WHERE delnum = lw_final-delnum.

IF SY-TABIX <> TABIX.

EXIT.

ENDIF.

ENDLOOP.

IF LW_FINAL2 <> LW_FINAL.

Hi Venu,

U r looping and reading the same table which does not make any sense.

pl find eg below:

loop at t_table1 into lw_table1 .

read table t_table2 with

key <field name>=lw_table1-Field name.(if require)

if sy-subrc = 0.

write Logic

else.

write Logic

endif.

endloop.

Cheers.
