Field Symbol issue

[Former Member]

Hi,

I am using field symbols for storing name in f_zzname field.

first of all I am assigning component 86 (which is zzname) of <wa_covp_ext> to <f_zzname>.

and then selecting sname in <f_zzname> from pa0001 table.

but then value of this <f_zzname> is not reflecting in <wa_covp_ext>.

Finally I want to get the zzname value in <fs>.

Can anyone help with this?

LOOP AT <fs> ASSIGNING <wa_covp_ext>.

ASSIGN COMPONENT 86 OF STRUCTURE <wa_covp_ext> TO <f_zzname>.

IF sy-subrc = 0.

ASSIGN COMPONENT 158 OF STRUCTURE <wa_covp_ext> TO <f_pernr>.

IF sy-subrc = 0.

ASSIGN pa0001-sname TO <f_zzname>.

SELECT SINGLE sname INTO <f_zzname> FROM pa0001

WHERE pernr = <f_pernr>

AND endda GE sy-datum

AND begda LE sy-datum.

IF sy-subrc EQ 0.

MODIFY <fs> FROM <wa_covp_ext>.

ENDIF.

ENDIF.

ENDIF.

ENDLOOP.

Hi

U're assigning <f_zzname> again:

The first assignment:

ASSIGN COMPONENT 86 OF STRUCTURE <wa_covp_ext> TO <f_zzname>.

The second assignment:

ASSIGN pa0001-sname TO <f_zzname>.

If you wan to select the data from pa0001 and move it to <wa_covp_ext>, you don't need the second assignment:

LOOP AT <fs> ASSIGNING <wa_covp_ext>.
  ASSIGN COMPONENT 86 OF STRUCTURE <wa_covp_ext> TO <f_zzname>.
  IF sy-subrc = 0.
    ASSIGN COMPONENT 158 OF STRUCTURE <wa_covp_ext> TO <f_pernr>.
      IF sy-subrc = 0.
*ASSIGN pa0001-sname TO <f_zzname>. "<------- It doesn't need it
       SELECT SINGLE sname INTO <f_zzname> FROM pa0001
          WHERE pernr = <f_pernr>
                AND endda GE sy-datum
                AND begda LE sy-datum.
*        IF sy-subrc EQ 0.                                "<------- It doesn't need it
*          MODIFY <fs> FROM <wa_covp_ext>. "<------- It doesn't need it
*        ENDIF.                                                "<------- It doesn't need it
      ENDIF.
   ENDIF.
ENDLOOP.

P.s.: if you use field-symbols u don't need MODIFY statament, but <FS> will be updated automatically: the field-symbol is a pointer so the data is move to the record of the internal table automatically.

Thanks Max. it solved my problem.

Remove

ASSIGN pa0001-sname TO <f_zzname>.

as it is undoing the assignment done to <f_zzname>, by

ASSIGN COMPONENT 86 OF STRUCTURE <wa_covp_ext> TO <f_zzname>.

that links <f_zzname> to the internal table row that you are looping
