Modify Dynamic Internal table content ?

[Former Member]

Dear All,

I want to modify the dynamic table content .

i.e. I have a Date value in the dyn. int. table and I want to modify it to the Year value.

fied-symbol : <fs_year>    TYPE ANY.
  DATA: lv_string TYPE char20,
            lv_year   TYPE char04.

    LOOP AT <fs_t_son> ASSIGNING <wa_son>.
* Get the Field and Value for the Date/Year
      ASSIGN COMPONENT 'BUDAT'  OF STRUCTURE <wa_son> TO <fs_year>.
      IF sy-subrc = 0.
        CLEAR lv_string.
        MOVE <fs_year> TO lv_string.
        CLEAR lv_year.
        lv_year = lv_string.
      <fs_year> = lv_year.

" How to modify my dyn. int. table with this value of <fs_year>  now ????
      ENDIF.  " if sy-subrc = 0.  "Assign
endloop.

Any clues ???

Regards,

When using FIELD-SYMBOLS assignation during a LOOP, there is no need to MODIFY the internal table, you only need MODIFY when using work area. (Look at [Access Methods to Individual Table Entries|http://help.sap.com/erp2005_ehp_04/helpdata/EN/fc/eb3612358411d1829f0000e829fbfe/frameset.htm])

I suppose you have a BUDAT and a YEAR field in structure, so

LOOP AT <fs_t_son> ASSIGNING <wa_son>.
  ASSIGN COMPONENT 'BUDAT'  OF STRUCTURE <wa_son> TO <fs_date>.
  CHECK sy-subrc EQ 0.
  ASSIGN COMPONENT 'GJAHR'  OF STRUCTURE <wa_son> TO <fs_year>.
  CHECK sy-subrc EQ 0.
  <fs_year> = <fs_date>+0(4).
ENDLOOP.

HI

to modify ur table we dont need structure assignment. Do it like this:

fied-symbol : <fs_year> TYPE ANY.

DATA: lv_year TYPE char04.

LOOP AT <fs_t_son> ASSIGNING <wa_son>.

<wa_son>-year = lv_year.

endloop.

In your case by just assigning the desired value to work area will modify the internal table dynamically.

no need to use explicit data movement or modify statement.

Hi,

You have assigned field-symbols <wa_son> to line of <fs_t_son>

<fs_year> is pointing to BUDAT component of <wa_son>,

Hence any changes made to <f_year> will directly get changed in <wa_son> and hence your internal table. [As you are using field-symbols in both assignments].

Although, I am not able to understand functionality of this portion of your code -

CLEAR lv_string.
        MOVE <fs_year> TO lv_string.
        CLEAR lv_year.
        lv_year = lv_string.
      <fs_year> = lv_year.
