How to set white spaces between the fields in dataset??

Question

Hi all,
I am writing a set on information to from infotypes to a text file. Its a fixed width file. How do set white spaces in the fields for dataset?
Example:
TYPES: begin of header,
                filler(40)  type c,
                id(3)        type c,
                filler2(7) type  c,
                delimiter  type  c,
             end of header.
DATA header type header.
header-filler1 = ' '.
header-id       = '100'.
header-filler2 = ' '.
header-delimiter = cl_abap_char_utilities=>newline.   ( do it to get a new line)
my_table = header.
append my_table.
DATA: out_file(256) type C,
      codepage_ref type ref to CX_SY_CONVERSION_CODEPAGE,
      out_char type c,
      size type i,
      insert_string type string,
      insert_size type i.
  out_file = filename.
  open dataset out_file for output in text mode ENCODING NON-UNICODE.
  LOOP AT my_table.
    size = strlen( my_table ).
    insert_string = ''.
    DO size TIMES.
      offset = sy-index - 1.
      try.
          out_char = my_table+offset(1).
          IF out_char = SPACE.
            CONCATENATE insert_string '' INTO insert_string SEPARATED BY SPACE.
          ELSE.
            CONCATENATE insert_string out_char INTO insert_string.
            transfer insert_string to out_file NO END OF LINE .
            insert_string = ''.
          ENDIF.
        catch CX_SY_CONVERSION_CODEPAGE.
          insert_size = strlen( insert_string ) - 1.
          insert_string = insert_string(insert_size).
      endtry.
    ENDDO.
   transfer CL_ABAP_CHAR_UTILITIES=>NEWLINE TO out_file NO END OF LINE.
  ENDLOOP.
  close dataset out_file.
How do I get to insert the space for filler1 and filler2?

Answer 1

problem lies in the open dataset codes
Used:
open dataset out_file for output in text mode encoding non-unicode message msg.
if sy-subrc= 0.
loop at my_table.
transfer my_table to out_file
transfer cl_abap_char_utilities=>newline to out_file no end of line.
endloop.
