Hi all,

Why below code is going to continous loop it is never coming back...

LOOP AT it_zsft_terr_code INTO IS_zsft_terr_code.

LV_STRLEN = STRLEN( IS_zsft_terr_code-ZZTERCD ).

MOVE IS_zsft_terr_code-ZZTERCD+1(3) TO LV_ZZTERCD.

MOVE LV_ZZTERCD TO IS_zsft_terr_code-ZZTERCD.

APPEND IS_zsft_terr_code TO IT_zsft_terr_code.

IF LV_STRLEN = 4.

DELETE IT_zsft_terr_code.

ENDIF.

ENDLOOP.

Pls help

<b>APPEND IS_zsft_terr_code TO IT_zsft_terr_code.</b>

u are appending entries to the same table in the loop.

Hi Srikanth ,

The reason is that in the loop you are using the statement

<b>APPEND IS_zsft_terr_code TO IT_zsft_terr_code.</b>

which appends a new line to the internal table , thus the loop becomes an infinite loop because when you process the last record you add one more record , so this process goes on.

Hi ,

Your code will look like this

LOOP AT it_zsft_terr_code INTO IS_zsft_terr_code.
LV_STRLEN = STRLEN( IS_zsft_terr_code-ZZTERCD ).
IF LV_STRLEN = 4.
*" If length is 4 delete the entry
DELETE table T_zsft_terr_code from IS_zsft_terr_code.
else.
*"Get the string starting from 4'th Char
MOVE IS_zsft_terr_code-ZZTERCD+1(3) TO LV_ZZTERCD.

MOVE LV_ZZTERCD TO IS_zsft_terr_code-ZZTERCD.

MODIFY IT_zsft_terr_code from IS_zsft_terr_code transporting ZZTERCD

ENDIF.

ENDLOOP.

Hope this helps , reward points if reply is helpful.

Regards

Arun

Hi KOta,

Try this...simple code..

LOOP AT it_zsft_terr_code INTO IS_zsft_terr_code.

SHIFT IS_ZSFT_TERR_CODE-ZZTERCD.

MODIFY IT_ZSFT_TERR_CODE FROM IS_ZSFT_TERR_CODE .

ENDLOOP.

Cheers
