converting data types dynamically

[Former Member]

Hi all,

i am converting all data type to CHAR statically as below.

tasktype* (raw)* to comp1(char)

time(tims) to comp2(char)

LOOP AT vmc INTO wa_vmctmp.
    WRITE: wa_vmctmp-tasktype         TO wa_zvmctmp-comp1,
           wa_vmctmp-time             TO wa_zvmctmp-comp2,
           wa_vmctmp-entry_id         TO wa_zvmctmp-comp3,
           wa_vmctmp-counter          TO wa_zvmctmp-comp4,
           wa_vmctmp-mem_alloc_local  TO wa_zvmctmp-comp5,
    APPEND wa_zvmctmp  TO  zvmc1.
  ENDLOOP.

can anybody suggest me,how do i do it dynamically if i have the table data in a field symbol..

Hello Sam

You can use this on same way as you have coded, instead of use work area, you can use Field-Symbol

LOOP AT vmc ASSIGNING <FS>.
    WRITE: <fs>-tasktype         TO wa_zvmctmp-comp1,
           <fs>-time             TO wa_zvmctmp-comp2,
           <fs>-entry_id         TO wa_zvmctmp-comp3,
           <fs>-counter          TO wa_zvmctmp-comp4,
           <fs>-mem_alloc_local  TO wa_zvmctmp-comp5,
    APPEND wa_zvmctmp  TO  zvmc1.
  ENDLOOP.

However if you do not know exactly structure, you can use ASSIGN COMPONENT statement to refer unkown field

ASSIGN COMPONENT sy-index OF STRUCTURE <wa> TO <comp>.

Try something like

LOOP AT itab1 ASSIGNING <record>.
  DO.
    ASSIGN COMPONENT sy-index OF STRUCTURE <record> TO <source>.
    IF sy-subrc NE 0. EXIT. ENDIF.
    ASSIGN COMPONENT sy-index OF STRUCTURE record2 TO <target>.
    IF sy-subrc NE 0. EXIT. ENDIF.
    WRITE <source> TO <target>.
  ENDDO.
  APPEND record2 TO itab2.
ENDLOOP.

Hi Raymond Giuseppi

thank you,the reply is some thing what i was expecting.....

As i have more number of internal tables,could you tell me what may be structure of itab2 in your code

and record2... is static or dynamic..

As i was mentioning i have data in field symbol then itab1 is static i guess ..if it is so what may be structure of itab1

Thanks and Regards

Check the [CASTING|http://help.sap.com/abapdocu_702/en/abapassign_casting.htm] addition of the ASSIGN statement.
