About accessing IDoc structure

former_member611006 — Thu, 06 Aug 2009 09:10:56 GMT

Hi Experts,

I'm creating a SHPMNT04-IDoc for deliveries. For each position in the delivery, I want to modify the position no. (E1EDL24-POSNR) when the position type (E1EDL26-PSTYV) is eq "ZHUM".

I 'm editing a segment like this:

DESCRIBE TABLE idoc_data  LINES lc_va_line.
READ TABLE idoc_data      INDEX lc_va_line.
MOVE idoc_data-sdata      TO lc_wa_e1edl24.
......
MOVE lc_wa_e1edl24        TO idoc_data-sdata.
MODIFY idoc_data          INDEX lc_va_line.
CLEAR idoc_data.

... but how can I test a value in the substructure E1EDL26 and modify a value in the upper-structure E1EDL24 ?

Thanks a lot for support.

Regards,

David.

I hope you want help on the coding to modify the segment E1EDL24-POSNR then do like this..

Loop at Idoc_data.

If idoc_data-segnam = 'E1EDL24'.

READ TABLE idoc_data with key segnam = 'E1EDL26'.

if sy-subrc = 0.

MOVE idoc_data-sdata TO lc_wa_e1edl26.

if lc_wa_e1edl26-pstyv = 'zhum'.

modify the sgement E1EDL24

endif.

endloop.

hi,

there is an easier way to solve this.


data: lc_wa_e1edl24 type e1edl24.
data: lc_wa_e1edl26 type e1edl26.
field-symbold: <idoc_data> type edidd.

loop at idoc_data assigning <idoc_data>.

case <idoc_data>-segnam.


when 'E1EDL24'
lc_wa_e1edl24 = <idoc_data>-sdata.
... do your changes (remember posnr)
<idoc_data>-sdata = lc_wa_e1edl24.    "you don´t need to modify idoc_data.
when 'E1EDL26'.
lc_wa_e1edl26 = <idoc_data>-sdata.
... do your chnages. (use posnr)
<idoc_data>-sdata = lc_wa_e1edl26.    "you don´t need to modify idoc_Data


endcase.




endloop.

i think this should help you !

Hi guys,

thank you for your answers.

@ Alexander :

I used your coding like this:

IF segment_name EQ 'E1EDL24'.
        DESCRIBE TABLE idoc_data  LINES lc_va_line.
        READ TABLE idoc_data      INDEX lc_va_line.
        MOVE idoc_data-sdata       TO    lc_wa_e1edl24.
        READ TABLE      idoc_data WITH  KEY segnam = 'E1EDL26'.
        IF sy-subrc = 0.
          MOVE idoc_data-sdata TO       lc_wa_e1edl26.
          IF lc_wa_e1edl26-pstyv =      'ZHUM'.
             lc_wa_e1edl24-posnr = lc_wa_e1edl24-posnr + 9010.
          ENDIF.
        ENDIF.
        MOVE lc_wa_e1edl24    TO    idoc_data-sdata.
        MODIFY idoc_data          INDEX lc_va_line.
        CLEAR idoc_data.
      ENDIF.

... I think there is a problem when I update de internal table "idoc_data" with "MOVE lc_wa_e1edl24 TO idoc_data-sdata" because after reading the E1EDL26 segment, I've got another index. What do you think ?

Regards,

David

save the index (sy-index) for the E1EDL24 access !

As Gordon said, use one variable and assign the index value for the E1EDL24 read and use that in modify statement.
