Problem with the field-symbols

Question

Hi all,
        i am unable to delete the  data in the internal table.
        i am sending the code.
      BEGIN OF t_oprtn,
       budat LIKE afru-budat,
       vornr LIKE afru-vornr,
       grund LIKE afru-grund,
       gmein LIKE afru-gmein,
       gmnga LIKE afru-gmnga,
       expfl(1),
       END OF t_oprtn,
FIELD-SYMBOLS: <fs_collect>         TYPE STANDARD TABLE.
FIELD-SYMBOLS: <fs_wa_collect>      TYPE ANY.
    CREATE DATA i_collect TYPE STANDARD TABLE OF t_oprtn
                          WITH DEFAULT KEY.
    CREATE DATA wa_collect TYPE t_oprtn.
  ASSIGN i_collect->*       TO <fs_collect>.
  ASSIGN wa_collect->*      TO <fs_wa_collect>.
  SELECT abudat avornr agrund  aarbid astokz darbpl a~aufnr
         bplnbez cmaktx agmnga agmein
         INTO TABLE i_final
         FROM afru AS a INNER JOIN afko AS b
                                   ON aaufnr = baufnr
                        INNER JOIN makt AS c
                                   ON bplnbez = cmatnr
                        INNER JOIN crhd AS d
                                   ON aarbid = dobjid
         WHERE a~budat IN s_budat
LOOP AT i_final INTO wa_final.
  MOVE-CORRESPONDING wa_final TO <fs_wa_collect>.
    COLLECT <fs_wa_collect> INTO <fs_collect>.
  ENDLOOP
how to write a delete statement for -  <fs_collect>.
Plz tell me the delete statement where GMNGA is '0'.   " GMNGA IS A CONFIRM QUANTITY.
Plz reply its urgent.

Answer 1

Try:
field-symbols: <f_temp> type any.
loop at <fs_collect> assigning <fs_wa_collect>.
   assign component 'GMNGA' of structure <fs_wa_collect> to <f_temp>.
if <f_temp> is initial.
   delete <fs_collect>.
endif.
endloop.
