field symbol with table field

[Former Member]

Hi !

here is my problem :

I have a table define like this :

matnr XXXX01 YYYY01 ZZZZ01 XXXX02 YYYY02 ZZZZ02 XXXX03 YYYY03 ZZZZ03 ... up to 12

when i read the header, i want to select the first field that is empty (for exemple XXXX02) and see if the next one (XXXX03) is filled. IF the next one is not filled i want to take the next until i found one that is filled. for exemple XXXX05 and then put the value in the first one (XXXX02).

So my probleme is that i don't know what is the name of the field. I tried something with the field symbol but i don't know how it work.

I'd like to wrote something like that :

IF itab-<fs> IS INITIAL.

<fs> would be the concatenation of XXXX and a counter (01,02,03...).

Thanks for you help !

Hi,

You can try.

Assign component wf_field of structure itab to <fs>.

Then check

if <fs> is initial.

where wf_field will store the name of the field.

Try to implement logic like this in your code:

Data: l_fldname(30),
l_cnt(2) type n.

Loop at itab.
Do 12 times.
l_cnt = l_cnt + 1.
concatenate 'ITAB-XXXX' l_cnt into l_fldname.
assign (l_fldname) to <FS>.

if not <FS> is initial.
exit.
endif.
enddo.
endloop.

thank you very much, but i still have a problem.

I wrote this and the test doesnt work (wt_month is a table with 01, 02, 03, ...)

LOOP AT wt_month.

CLEAR wv_found.

wv_index = sy-tabix.

CONCATENATE wc_zone1 wt_month-month INTO wv_zone.

ASSIGN COMPONENT wv_zone OF STRUCTURE wt_final_new TO <wf_zone1>.

IF <wf_zone1> IS INITIAL.

wv_index = wv_index + 1.

LOOP AT wt_month2 FROM wv_index.

CONCATENATE wc_zone1 wt_month2 INTO wv_zone.

ASSIGN COMPONENT wv_zone

OF STRUCTURE wt_final_new TO <wf_zone2>.

IF NOT <wf_zone2> IS INITIAL.

<wf_zone1> = <wf_zone2>.

LOOP AT wt_zone.

CONCATENATE wt_zone-zone wt_month-month INTO wv_zone.

ASSIGN COMPONENT wv_zone

OF STRUCTURE wt_final_new TO <wf_zone1>.

CONCATENATE wt_zone-zone wt_month2-month INTO wv_zone.

ASSIGN COMPONENT wv_zone

OF STRUCTURE wt_final_new TO <wf_zone2>.

<wf_zone1> = <wf_zone2>.

ENDLOOP.

wv_found = 'X'.

ENDIF.

ENDLOOP.

IF wv_found IS INITIAL.

• SELECT

ENDIF.

ENDIF.

ENDLOOP.

Change your first assign statement like this:

ASSIGN COMPONENT wv_zone OF STRUCTURE <b>WT_MONTH</b> TO <wf_zone1>.

no wt_month is a table with numbers (01,02,03...), i use this instead of an incrementation for other reasons.

please i really need your help.

maybe the problem is the declaration of the field symbol ? I declare as type any.

[naimesh_patel]

It looks like, all your ASSIGN statments are right.

Put break point after the assign statment, check the content of your original field and field-symbol. You will some better idea, what is going wrong.

I use this code to sweep all the fields in a table...

  loop at t_asgnas.
    clear v_linea.
    do 137 times.
      clear v_campo.
      assign component sy-index of structure t_asgnas to <campo>.
      v_campo = <campo>.
      shift v_campo left deleting leading space.
      v_len = strlen( v_campo ).
      if v_len <= 0. v_len = 1. endif.
      concatenate v_linea
                  v_campo+0(v_len)
                  into v_linea separated by '^'.
    enddo.
  write / v_linea.
  endloop.

You could change the logic and make it skip 3 fields everytime, as to land on the XXXX__ fields on every cycle.

I would try to code with your logic but i don't have the time right now... I hope you find use to it.
