loop at Field symbol

Former Member — Mon, 10 Mar 2008 10:27:02 GMT

Hi,

I'm new to ABAP and need some urgent help.

I have a FS which is assigned to a table, i now need to access values in that table and delete a few entries.

Im doing the following for the same.

*<fs_alv_histd> is already assigned to a table and has values

FIELD-SYMBOLS: <fs_wa> type ANY.

loop at <fs_alv_histd> assigning <fs_wa>.

if <fs_wa>-OIL_DISP= 0 .

code for delete

endif.

endloop.

However im getting an error sayinf <fs_wa> has no structure and therefore no component named OIL_DISP.Can anyone help please.

Hi you defined field symbol work area as generic type, declare like this and check it out...

<fs_alv_histd> is your intenal table.

FILED-SYMBOLS: <fs_wa> LIKE LINE OF <fs_alv_histd>.

LOOP AT <fs_alv_histd> INTO <fs_wa>.

your code...

ENDLOOP.

Reward pts if it helps....

hi Rahul,

you have to assign the field as well to another field symbol:

DATA : <fs_field> TYPE ANY.

loop at <fs_alv_histd> assigning <fs_wa>.

ASSIGN COMPONENT 'OIL_DISP' OF STRUCTURE <fs_wa> TO <fs_field>.

if <fs_field> = 0 .

==> code for delete

...

hope this helps

Hi,

Please refer to the below code:



  FIELD-SYMBOLS:  <pos_data> TYPE ANY,
                               <gt_pos_data>  TYPE table.

  DATA : lt_csks LIKE gt_csks WITH HEADER LINE.


 LOOP AT <gt_pos_data> ASSIGNING <pos_data>.

    MOVE-CORRESPONDING <pos_data> TO lt_csks.
    
    if lt_csks-oi_disp NE 0.
       APPEND lt_csks.
      CLEAR  lt_csks.
   endif.

  ENDLOOP.

In your lt_cks you will have only data which does not have oil_disp not equal to zero.

Thanks,

Sriram Ponna.

FIELD-SYMBOLS: <fs_dyn_table> TYPE STANDARD TABLE.

DATA gf_line LIKE LINE OF <fs_dyn_table>.

you have to assign each field to another field symble then you can handle the value. Try it

ASSIGN COMPONENT <field name> OF STRUCTURE <fs_wa> TO <fs_field>.

IF <fs_field> EQ 'Give value here'.

Write code here

ENDIF.

Example field-symbol at exit & get value from other exit.

DATA: it_vbpa LIKE vbpa.
FIELD-SYMBOLS: <fs> TYPE any,
<fs_data> TYPE table.
ASSIGN ('(SAPMV56A)XVBPA[]') to <fs_data>.
LOOP AT <fs_data> ASSIGNING <fs>.
MOVE-CORRESPONDING <fs> to it_vbpa.
IF it_vbpa-vbeln = i_xvttk-tknum.
.......
ENDIF.
ENDLOOP.

Can we set watchpoint over the field symbols? while using in loop statement? IF yes means what is the syntax
