Hi,

I do not what is the code you written. Check the sample program RSDEMO02.

Check this and tell if the issue is not resolved.

Hi Madhu Rao,

If I modify the key fields the problem will be arised.

In Flow logic.

LOOP .

MODULE tbc_modify ON CHAIN-REQUEST.

MODULE tbc_mark.

ENDLOOP.

In module.

MODULE tbc_modify INPUT.

MODIFY t_data

FROM fs_data

INDEX tbc-current_line.

IF sy-subrc NE 0.

APPEND fs_data TO t_data.

ENDIF.

ENDMODULE.

MODULE tbc_mark INPUT.

DATA: tbc_wa2 LIKE LINE OF t_data.

IF tbc-line_sel_mode = 1

AND fs_data-mark = 'X'.

LOOP AT t_data INTO tbc_wa2

WHERE mark = 'X'.

tbc_wa2-mark = ''.

MODIFY t_data

FROM tbc_wa2

TRANSPORTING mark.

ENDLOOP. .

ENDIF.

MODIFY t_data FROM fs_data

INDEX tbc-current_line

TRANSPORTING mark.

ENDMODULE.

Hai,

You cannot modify the key fields, when u try to do that Modify statement will insert a new line with the modified data. so what you can do is delete the old line and save the new one.

Best regards,
