Reading a PDF data after uploading through GUI_UPLOAD

Former Member — Tue, 02 Jan 2007 10:05:14 GMT

Hello all,

I have a situation.

I am reading a PDF document using GUI_UPLOAD.

Now the contents in the internal table are in binary format in form of Astreiks and other characters

It is possible to convert the contents to the text format.

Because i have to read the contents and manipulate accordingly.

thanks in advance.

Regards,

Krishna

Hello Anurag,

I am already doing the same thing exactly as mentioned below.

But once you upload the PDF file the internal table contents will be in the Binary format. But i want to see the contents as text as i want to manipulate the data from PDF.

Is there any way ?

Thanks.

Hello Krishnakumar ,

I am facing the same problem .

I changed that Binary data into text by using SCMS_BINARY_TO_TEXT.

But it is not in readable format ( String ).

So, Did you solve this .If yes Let me know.

Regards,

B. Krishna.

Hello friend,

as far as I know, if a PDF meets with following prerequisite, it is possible to extract text information from such PDF

1. a PDF which is rendered by ADS ( Adobe Document Service ). For example , all PDF rendered in SAP Business by Design is rendered by ADS.

2. a PDF which is interactive form. Actually from technical point of view, a interactive PDF consists of template ( xdp file ) and xml file. In the PDF generation the two is merged into PDF by ADS. So it is possible to extract text information ( xml format ) from such PDF.

You can use the following code to extract text information from such PDF.

PROGRAM fp_pdf_test_03.
* Extract data.

INCLUDE fp_utilities.

SELECTION-SCREEN BEGIN OF BLOCK s_files WITH FRAME TITLE text-100.
PARAMETERS: p_pdf TYPE localfile VISIBLE LENGTH 64 OBLIGATORY,
            p_xml TYPE localfile VISIBLE LENGTH 64 OBLIGATORY.
SELECTION-SCREEN END OF BLOCK s_files.
SELECTION-SCREEN BEGIN OF BLOCK s_conn WITH FRAME TITLE text-101.
PARAMETERS p_dest TYPE rfcdest OBLIGATORY.
SELECTION-SCREEN END OF BLOCK s_conn.

DATA: l_fp     TYPE REF TO if_fp,
      l_pdfobj TYPE REF TO if_fp_pdf_object,
      l_pdf    TYPE xstring,
      l_data   TYPE xstring,
      l_fpex   TYPE REF TO cx_fp_runtime.

INITIALIZATION.
  MOVE cl_fp=>get_ads_connection( ) TO p_dest.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_pdf.
  PERFORM value_help_for_file USING 'PDF' CHANGING p_pdf.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_xml.
  PERFORM value_help_for_output_file USING 'XML' CHANGING p_xml.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_dest.
  PERFORM value_help_for_destination USING 'P_DEST'.

START-OF-SELECTION.

  PERFORM load_file USING p_pdf CHANGING l_pdf.

* Get FP reference.
  l_fp = cl_fp=>get_reference( ).

  TRY.
* Create PDF Object.
      l_pdfobj = l_fp->create_pdf_object( connection = p_dest ).

* Set document.
      l_pdfobj->set_document( pdfdata = l_pdf ).

* Tell PDF object to extract data.
      l_pdfobj->set_task_extractdata( ).

* Execute, call ADS.
      l_pdfobj->execute( ).

* Get the result.
      l_pdfobj->get_data( IMPORTING formdata = l_data ).

    CATCH cx_fp_runtime_internal
          cx_fp_runtime_system
          cx_fp_runtime_usage INTO l_fpex.
      PERFORM error USING l_fpex.
  ENDTRY.

* Download data.
  PERFORM download_file USING l_data p_xml.

Hi Jerry,

I have a similar requirement and I copied your code and executed the program. But I got below error.

ADS: com.adobe.ProcessingException: Error exporting Data into PDF - PDF Exception: Invalid object for the XFA entry in the forms dictionary

Please help me on this?

Thanks
