Problem With Class CL_DOCUMENT_BCS

Former Member — Thu, 09 Aug 2007 23:35:49 GMT

Hello! I hope someone could help me on this one...

I am now trying to develop a program that sends an email with multiple pdf attachments. I saw in one of the threads I think that an alternative to using the function modules is to use methods. The steps I did prior to the email subroutine are the following:

1. Call the Smartform to return an OTF table

2. Convert the OTF Using the 'CONVERT_OTF' function

3. Call the email subroutine

Now I am having some problems with the following code:

    document = cl_document_bcs=>create_document(
               i_type = 'RAW'
               i_text = text
               i_length = '12'
               i_subject = '' ).

*--- Add attachments
    IF NOT t_pdf_vrs[] IS INITIAL.
      CLEAR binary_content[].
         binary_content[] = t_pdf_vrs[].        "<==PROBLEM HERE
      CASE p_rtyp.
      WHEN 'V'.
        CONCATENATE 'VRS' p_lifnr sy-datlo
               INTO i_att_sub separated by '_'.
        CALL METHOD document->add_attachment
        EXPORTING
        i_attachment_type    = 'PDF'
        i_attachment_subject = i_att_sub
        i_att_content_hex    = binary_content.
      WHEN 'M',
      ENDCASE.
    ENDIF.

I get an error saying:

<b>"BINARY_CONTENT" and "T_PDF_VRS" are not mutually convertible. In Unicode programs, "BINARY_CONTENT" must have the same structure layout as "T_PDF_VRS", independent of the length of a Unicode character.</b>

The declarations of the tables in question are the following:

DATA binary_content TYPE solix_tab.
DATA t_pdf_vrs          LIKE tline OCCURS 0 with HEADER LINE.

The t_pdf_vrs table contains the <b>lines</b> parameter from the CONVERT_OTF fm.

Please help. Points for any helpful answer.

Thanks in advance.

chk both internal fields are same.

binary_content[] = t_pdf_vrs[].

refer the same strture.

Hi,

Try to use SX_OBJECT_CONVERT_OTF_PDF instead of CONVERT_OTF


CALL FUNCTION 'SX_OBJECT_CONVERT_OTF_PDF'
EXPORTING
format_src = 'OTF'
format_dst = 'PDF'
devtype = 'PRINTER'
len_in = lv_len_in
TABLES
content_in = lt_content_in
content_out = lt_content_out.

gt_pdfdata[] = lt_content_out[].

Hi aRs,

When I checked the FM you suggested, I got different parameters:

CALL FUNCTION 'SX_OBJECT_CONVERT_OTF_PDF'
  EXPORTING
    FORMAT_SRC            =
    FORMAT_DST            =
*   ADDR_TYPE             =
*   DEVTYPE               =
*   FUNCPARA              =
  CHANGING
    TRANSFER_BIN          =
    CONTENT_TXT           =
    CONTENT_BIN           =
    OBJHEAD               =
    LEN                   =
* EXCEPTIONS
*   ERR_CONV_FAILED       = 1
*   OTHERS                = 2
          .

The CONVERT_OTF_2_PDF function returns the PDF data in a table of STRUCTURE TLINE which has lines of 134 characters long (2 + 132). The send email functions or methods want the data in a structure of length 255 (TYPE SOLI_TAB).

The returned PDF data is actually binary data, so you need to combine the input table entries as a single long string, and then split this into the output as blocks of 255 characters. Take care using CONCATENATE to do this - it trims spaces which corrupts the PDF if you do not have the RESPECTING BLANKS addition.


  DATA: l_str TYPE string.
  LOOP AT it_input.
    CONCATENATE l_str it_input INTO l_str RESPECTING BLANKS.
  ENDLOOP.

  DATA: l_len TYPE i.
  DO.
    l_len = STRLEN( l_str ).
    IF l_len = 0. EXIT. ENDIF.
    IF l_len > 255. l_len = 255. ENDIF.
    it_output = l_str+0(l_len).
    APPEND it_output.
    l_str = l_str+l_len.
  ENDDO.

Hi Andrew!

Thanks for the info. It was a bit weird because the function SX_OBJECT_CONVERT_OTF_PDF have different parameters from the ones given by aRs, but checking the function code itself I discovered that formatting of the table is very much similar to the code you gave. Will try this. Thanks again!
