Field Symbol assignment

[Former Member]

Hello All,

I want to check whether a fiedsymbol has been assigned or not.

How to do that ?

Here is my code .

LOOP AT <dyn_table> ASSIGNING <dyn_wa>.
    WHILE sy-subrc = 0.
      ASSIGN COMPONENT 'MBLNR' OF STRUCTURE <dyn_wa> TO <fs_mblnr>.
      ASSIGN COMPONENT 'MJAHR' OF STRUCTURE <dyn_wa> TO <fs_mjahr>.
      ASSIGN COMPONENT 'ZEILE' OF STRUCTURE <dyn_wa> TO <fs_zeile>.
      ASSIGN COMPONENT 'WERKS' OF STRUCTURE <dyn_wa> TO <fs_werks>.
      ASSIGN COMPONENT 'LIFNR' OF STRUCTURE <dyn_wa> TO <fs_lifnr>.

      SELECT SINGLE * FROM mseg WHERE mblnr = <fs_mblnr>
                                AND   mjahr = <fs_mjahr>
                                AND   zeile = <fs_zeile>.
      IF sy-subrc ne 0.

        MESSAGE s046 DISPLAY LIKE 'E' WITH text-034 text-035.

      ELSE.

        CLEAR gs_edidc.

      ENDIF.

    ENDWHILE.




  ENDLOOP.

In the above code if the fieldsymbol is not assigned then in the Select Statement the Program goes for a short dump saying "FIELD SYMBOL NOT ASSIGNED ".

SO before making a SELECT Query I want to check whetehr the FS is assigned or not .

How to check it ?

Hi Deepu,

Simple thing is to do an EPC.( Extended Program Check). If your field symbol is not used anywhere then it would show up as a field attribute error.
