Dynamic Internal table values read and assign it back

Former Member — Tue, 22 Jan 2008 09:13:02 GMT

Hi All,

I want to get the internal table field name dynamically and fetch its value and do some calculation and asign the new value to the same field name.

CONCATENATE '<WA_PIPE>-ZW' v_index INTO v_fld.

CONDENSE v_fld NO-GAPS.

FIELD-SYMBOLS <fs> TYPE ANY.

ASSIGN (v_fld) TO <fs>.

v_fld1 = <fs> * <wa_pipe>-zrate.

Now i've the internal table field name as <WA_PIPE>-ZW1 in v_fld and v_fld1 is having the value of the same field.

How to assign it to the internal table field.

Thanks.

Ashok

hi Ashok,

you have to use the ASSIGN COMPONENT field OF STRUCTURE wa TO <fs> statement!

hope this helps

Field name Field contents

v_fld <WA_PIPE>-ZW1

How to assign <wa_pipe>-zw1 value as 32000.

Thanks,

Hello Ashok

Below is a sample coding which shows how to work with dynamic itabs and field symbols:



LOOP AT <lt_itab>  ASSIGNING <ls_record>.
  CONCATENATE '<WA_PIPE>-ZW' v_index INTO v_fld.
  CONDENSE v_fld NO-GAPS.

  ASSIGN COMPONENT v_fld      OF STRUCTURE <ls_record> to <ld_fld>.
  ASSIGN COMPONENT 'ZRATE' OF STRUCTURE <ls_record> to <ld_zrate>.

  <ld_fld> = <ld_fld> * <ld_zrate>.
  " NOTE: Since we are working with field symbols there is no need to make
  "            a modify of the itab since it is immediately updated
ENDLOOP.

Regards

Uwe
