How can I access data whose field name is in itab?

[acamli]

Hi everyone,

I have an itab is name my_itab. This itab has stored a some variable names in fields0.

For example; my_itab-fields0 has fields name like my_itab2-field2.

I need a my_itab2-field2 values in loop.

I tried something but I can not access the field data.

DATA: my_itab TYPE  OCCURS 0 WITH HEADER LINE.

FIELD-SYMBOLS: <field> TYPE ANY.

DATA: i_field TYPE REF TO DATA.

DATA: lv_sum TYPE p DECIMALS 2.

lv_sum = 0.

...

LOOP AT my_itab.
ASSIGN COMPONENT my_itab-fields0 TO <field>.
lv_sum = lv_sum + <field>.
ENDLOOP.

my_itab-fields0 stored my_itab2-fields2 name.

I want to get a data my_itab2-fields2 value in loop.

Thank you anyone who helps.

should be somethind like

loop at my_itab
    reference into data(o_line_itab).
   data(my_field) = conv fieldname( o_line_itab->fields0 ).
   assign (my_field) into field-symbol(<my_field>).
  check <my_field> is assigned and sy-subrc eq 0.
   lv_sum = ..... <my_field>.
endloop.

When I change the assign code it was solved my problem.

DATA: my_itab TYPE  OCCURS 0 WITH HEADER LINE.

FIELD-SYMBOLS: <field> TYPE ANY.

DATA: i_field TYPE REF TO DATA.

DATA: lv_sum TYPE p DECIMALS 2.

lv_sum = 0.

...

LOOP AT my_itab.
ASSIGN (my_itab-fields0) TO <field>.
lv_sum = lv_sum + <field>. 
ENDLOOP.
