Problem of sending email with attachment by SO_NEW_DOCUMENT_ATT_SEND_API1

Question

Hi experts,
When I sent email with FM 'SO_NEW_DOCUMENT_ATT_SEND_API1' with TXT attachment, I found the there were no new line after each row of the content of TXT file attachment . All the rows in the internal table are concatenated into a string without any new line mark. It damaged the format of my attachment.

You need to concatenate your text with  l_c_cr_lf  (For enter button or new line) after every 255 char to get new line. Below is the code.  Let me know in case of ny clarifications.
CONSTANTS:  l_c_cr_lf    TYPE abap_cr_lf VALUE cl_abap_char_utilities=>cr_lf,
              l_c_255 TYPE char3 VALUE '255'.
DATA: l_v_cr_lf TYPE abap_cr_lf,
        l_v_n TYPE i,
        l_v_dif TYPE i,
        l_v_strlen TYPE i.
l_v_cr_lf = l_c_cr_lf.
  l_v_n = 0.
  LOOP AT fp_i_mail_out INTO wa_mail_out.
    l_v_strlen = STRLEN( wa_mail_out ).
    CLEAR l_v_n.
    DO.
      l_v_dif = l_v_strlen - l_v_n.
      IF l_v_dif < l_c_255.
        EXIT.
      ELSE.
        l_wa_attachment =  wa_mail_out+l_v_n(255).
        APPEND l_wa_attachment TO l_i_attachment.
        CLEAR l_wa_attachment.
        l_v_n = l_v_n + 255.
      ENDIF.
    ENDDO.
    IF l_v_strlen > l_v_n.
      l_v_dif = l_v_strlen - l_v_n.
      l_wa_attachment =  wa_mail_out+l_v_n(l_v_dif).
      APPEND l_wa_attachment TO l_i_attachment.
      CLEAR l_wa_attachment.
    ENDIF.
    DESCRIBE TABLE l_i_attachment LINES l_v_lines.
    LOOP AT l_i_attachment ASSIGNING <l_fs_attach>.
      IF sy-tabix = l_v_lines.
        CONCATENATE <l_fs_attach>-line l_v_cr_lf  INTO <l_fs_attach>-line.
      ENDIF.
    ENDLOOP.
  ENDLOOP.
