Generating PDF in Web-Dynpro

[#1]

Hello,

I have a problem with generating a PDF file with ABAP WebDynpro. I have an ALV and there I read a line. From this line I want to build a smartform which should be converted into PDF. I think my coding works. I have no syntax errors and when I debug the coding, everything looks good. I also get my popup that I want to have. But then I got an error: "File does not begin with '%PDF-'."

I look for this error here in SDN but I could not find a solution. I have also tried to do what is mentioned in note 1042424.

Can anybody helps me?

If you have a binary pdf (xstring), you can give an output via element "InteractiveForm".

This also supports display of common pdfs generated by smartforms.

Just unmark "enabled" in that element.

Thank you for your very quick reply.

In the view for the PDF I have the element "InteractiveForm" and I unmark "enabled".

Now I got no errors, but the popup is empty.

Here are my last rows of coding:

data: pdf_size type i,
        pdf_data type xstring,
        lt_otf      TYPE  tsfotf,
        lt_pdf     TYPE  STANDARD TABLE OF tline.


CALL FUNCTION 'CONVERT_OTF'
      EXPORTING
        format                = 'PDF'
*        max_linewidth         = 132
      IMPORTING
        bin_filesize          = pdf_size
        bin_file              = pdf_data
      TABLES
        otf                   = lt_otf   
        lines                 = lt_pdf   
      EXCEPTIONS
        err_max_linewidth     = 1
        err_format            = 2
        err_conv_not_possible = 3
        err_bad_otf           = 4
        OTHERS                = 5.

  if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
    with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  endif.

  data:
        node_pdf     type ref to if_wd_context_node,
        elem_pdf     type ref to if_wd_context_element,
        stru_pdf     type        if_componentcontroller=>element_pdf ,
        item_source  like        stru_pdf-source.

* navigate from <CONTEXT> to <PDF> via lead selection
  node_pdf = wd_context->get_child_node( name = if_componentcontroller=>wdctx_changing ).
* get element via lead selection
  elem_pdf = node_pdf->get_element( ).
* set single attribute
  elem_pdf->set_attribute(
    exporting
      name = `PDF`
      value = pdf_data ).

Which fields/tables should be filled that I get results in the popup?

Thanks for your help.

Hi Markus

Where are you writing these lines of code ?

Have you ever generated smartforms, before.

The OTF function needs the output of your smartform in order to generate a pdf.

You need to generate your smartform like this:

data ls_control_pars type ssfctrlop.
data ls_ouput_options type ssfcompop.
data ls_output type ssfcrescl.

call function 'FUNCTION_MODULE_NAME'
 exporting
   control_parameters = ls_control_pars
   outout_options       = ls_output_options
   user_settings         = false
   .
   .
importing
  job_outputinfo       = ls_output

then

call function 'CONVERT_OTF'
  exporting
    format = 'PDF'
  importing
   bin_filsize = l_file_size
   bin_file = l_xstring
 tables
  otf = ls_output-otfdata

 lines = lt_lines.

the element lt_lines can be defined as dummy.

But this is just pseudo code. You need to have know how in generating smartforms.
