Can we declare a field-symbols <fs> with a header line?

[Former Member]

I can declare:

FIELD-SYMBOLS: <fs> TYPE STANDARD TABLE.

But this <fs>[] doesn't have a headline. How can I declare this <fs> with a header line?

Thanks.

I would suggest not using a header line. Use a seperate work area instead. Here is an example.

report zrich_0001 .

Types: begin of ttab,
       fld1 type c,
       fld2 type c,
       end of ttab.
data: itab type table of ttab.
data: WA like line of itab.

field-symbols: <fs> type standard table.
field-symbols: <fs_wa>.

wa-fld1 = 'A'.
wa-fld2 = '1'.
append wa to itab.

wa-fld1 = 'B'.
wa-fld2 = '2'.
append wa to itab.

assign itab to <fs>.
assign wa   to <fs_wa>.

loop at <fs> into <fs_wa>.
  write:/ <fs_wa>.
endloop.

You can't.

field-symbol is like the pointer in C language. Try to implement code like this one:

create data w_field like line of <internal_table_field>.

assign w_file->* to <structure_field>.

where w_field is "type ref to data".

hi,

example

DATA : IT_QALS LIKE i_QALS OCCURS 0 WITH HEADER LINE.

FIELD-SYMBOLS <FS> LIKE i_QALS.

ASSIGN i_QALS TO <FS>.

In this case, you can try this

FIELD-SYMBOLS: <fs> TYPE STANDARD TABLE.

FIELD-SYMBOLS : <FS_LINE> LIKE LINE OF <FS>.
