How to download PDF output forms to presentation server without display

Question

Hi All,
My requirement is to download the Sales Order forms and save it in local system.
I have created a custom program where I am passing a range of Sales Order no, Partner Function, Output type and Application as my input in selection screen.
Logic:
I am calling my Sales Order Abodeform using the FM: 'FP_FUNCTION_MODULE_NAME' and thereby I got the function module name of my form.
Then I am calling the FM:
Input to the FM:  
  ls_outputparams-nodialog = abap_true.
  ls_outputparams-authority = 'X'.
  ls_outputparams-getpdf = 'X'.
  ls_outputparams-dest = 'LP03'.
  ls_outputparams-nopreview = abap_true.
  ls_outputparams-reqimm = abap_true.
  CALL FUNCTION 'FP_JOB_OPEN' 
    CHANGING
      ie_outputparams = ls_outputparams
    EXCEPTIONS
      cancel          = 1
      usage_error     = 2
      system_error    = 3
      internal_error  = 4
      OTHERS          = 5.
followed by,  CALL FUNCTION (FM name)
     EXPORTING
      archive_index        = toa_dara
      archive_parameters   = arc_params
      control_parameters   = ls_control_param
      mail_recipient       = ls_recipient
      mail_sender          = ls_sender
      output_options       = ls_output_param
      user_settings         = ' '
      is_nast                 = nast
      is_vbdka               = vbdka
      is_addres             = addr_key
    IMPORTING
      document_output_info = document_output_info
      job_output_info      = job_output_info
      job_output_options   = job_output_options
    TABLES
      it_vbdpa             = tvbdpa    "Item information
      it_vbdpau            = tvbdpau   "Subitem numbers
      it_vedpa             = tkomservp  "Contract Item Validity
      it_vedka             = tkomservh  "Contract Header Validity
      it_vedpn             = tkomservpn "Contract Item Cancellation Data
      it_vedkn             = tkomservhn "Contract Header Cancellation DA
    EXCEPTIONS
      formatting_error     = 1
      internal_error       = 2
      send_error           = 3
      user_canceled        = 4
      OTHERS               = 5.
then ,  CALL FUNCTION 'FP_JOB_CLOSE'
    IMPORTING
      e_result       = ls_result
    EXCEPTIONS
      usage_error    = 1
      system_error   = 2
      internal_error = 3
      OTHERS         = 4.
then i am using the below FM to get the OTF data if any available.
CALL FUNCTION 'CONVERT_OTF'
    EXPORTING
      format                = 'PDF'
    IMPORTING
      bin_filesize          = lv_binfilesize
      bin_file              = lv_bin_file
    TABLES
      otf                   = ls_output_info-otfdata-> i am not sure which data to pass here. i am getting sy-subrc value as 4.
      lines                 = lt_lines
    EXCEPTIONS
      err_max_linewidth     = 1
      err_format            = 2
      err_conv_not_possible = 3
      err_bad_otf           = 4
      OTHERS                = 5.
Now I dont no how to link the PDF forms to below method.
CALL METHOD cl_gui_frontend_services=>gui_download
    EXPORTING
      bin_filesize = v_size
      filename     = D://x.pdf
      filetype     =   'BIN'
    CHANGING
      data_tab     = lt_pdf.
Because in smartforms, we will convert the OTF output to PDF and that value is passed to GUI_DOWNLOAD FM as input (lt_pdf) , whereas in adobeforms the output itself is in PDF so i dont how to retreive the values from adobeforms and pass it to the above FM, so that I can save 'N' no. of sales order outputs in one PDF file.
Kindly help me out in this.
Thanks & Regards,

Hi Vishnu,
I read the GUI_DOWNLOAD FM documentation, if I am trying to download binary type of file, It is mandatory to pass file size.
In my case, since I am having PDF file, so i don't no how to get the size of the pdf file.
As you said, if i use Convert_OTF FM, i don't have data to pass to the OTF and LINES tables.
I am having values of PDF in xstring format in ls_output1-pdf, which i got using the below FM.
CALL FUNCTION lv_funcname (FM name)
    EXPORTING
      /1bcdwb/docparams  = ls_docparams
      is_vbdka           = vbdka
    IMPORTING
      /1bcdwb/formoutput = ls_output1
    EXCEPTIONS
      usage_error        = 1
      system_error       = 2
      internal_error     = 3
      OTHERS             = 4.
Kindly tell me what values i need to pass to the FM you mentioned in order to get the size of the file.
Thanks & Regards,

But still I am not sure, how the pdf output is coming for single input whereas if i give in a range, its failing. In single input, i am not giving binary file size still the output is coming.. but for range its not. Kindly help me out in this.
