to open pdf from binary text itab

[Former Member]

Hi friends,

I have a PDF in app server which i am reading into a binary text form into an internal table.

Below code:

data: begin of itab occurs 0,
field(256),
end of itab.
data: dsn(100) value '/usr/sap/xfr/FIS/testpdf',

open dataset dsn for input in binary mode.
 
do.
read dataset dsn into itab-field.
if sy-subrc = 0.
append itab.
else.
exit.
endif.
enddo.

Now how do i launch this PDF by using this binary text in ITAB.

I know i can download on to presentation server using GUI_Download, and then opening the same using CL_GUI_FRONTEND_SERVICES=>EXECUTE

but i don't want to do that.

Is there any way to launch / render this PDF on UI.

Any inputs on this is highly appreciated.

using HTML Viewer you can get that..pass the PDF and generate the URL and use the same for display .show URL will take care of that.

data:    v_html_alignment type i,
           v_numbytes type i,
           v_mode type char1,
           v_url(255) type c,
           v_pdf     like sopcklsti1-doc_type value 'PDF',
           v_application(11) type c value 'application',
           lt_pdf  type table of tline.

You can use the above code.

Hi Vijay,

Thanks for your inputs.

I used the code but just populated lt_pdf like below.

LOOP AT ITAB.
  LS_PDF-TDLINE = ITAB-FIELD.
  APPEND LS_PDF TO LT_PDF.
ENDLOOP.

but its not working i am getting HTML000001.pdf in V_URL in load_data method but show_url is not working.

What is wrong with my code?

Simha

Hi simha,

As you say that you do not want to download the file

on presentation server (front end) and open it --

But that would really happen if at all there is some

FM which would directly open the file.

Eg. When we open a file on browser thru a link,

the file actually gets downloaded on local machine

in some temporary folder under some temporary name,

and ONLY then it gets opened.

I don't see any other direct way in which a pdf file can

get opened, without getting downloaded & saved, behind the scenes.

Hi Amit,

I understand that anything that you open on your PC takes system memory but there should be a way to open the attachments using cl_htmlviewer or something.

What i want is, in a report on click of button i need to invoke the attaachment(either PDF/JPEG).

as i have this data as binary text in a cluster table, which i will retrieve on click of button into ITAB and invoke.

I am struck here in invoking this as i am not sure how to do using HTML control or any other better ways.

Regards,

Simha

Hi again,

1. Is there any specific reason that - behind the scenes -

you do not want to download the file on front end and then open it?

As per my personal opinion, there is no harm in doing it.

If we use a HTML viewer or anything, it will also do the

same behind the scenes.

when i download and open it, user knows that it is being downloaded and i don't want to do it as i feel its not the best way of giving the solution.

can't we invoke with out downloading?

[Former Member]

Hi,

1. If your concern is about the user knowing that the file

is downloaded,

then i would say that don't worry about that.

When we use GUI_DOWNLOAD then there is

no progress bar or any download icon on front-end,

that one can know what is really happening.

It would be almost instantaneous, unless the file is very big.

2. To get a taste of it, just copy paste.

a) this will download a .txt file with two lines

b) it will automatically open it in notepad.

report abc.

itab-line = 'This is line 2'.

Hi Amit,

Thanks for your patience inputs.

I will be downloading a file of size 3-5MB

So thats going to be huge and gives a message so many bytes transferred..

I don't want that to happen thats my intention.

Regards,

Simha

[Former Member]

Hi again,

If your concern is just about the message of xx bytes transferred,

then there is a small one line work around for it.

This will not show the standard message, instead

it will show our message which can be either blank,

or a simple message that 'Opening File'.

Just put this statement, immediately after gui_download.

*---------------- MESSAGE-----
message 'Opening File' type 'S'.
*------------------------------

Now run the program again, and u will see the difference.

I did the same for a file which is at desktop.

use function module GUI_UPLOAD in BIN format and put it into internal table.

then do whatever you want with the internal table and then take the output with GUI_DOWNLOAD FUNCTION MODULE.

this report will take any file from ur desktop and put into internal table.

from this internal table i am populating in one DB table for reference purpose and then again dumping it to somewhere in the local system.

Hi,

There was a similar requirement for our customer couple of years back and similar was our approach, but with time customer faced lot of performance issues and as the DB space grows table space allocation became tedious for DBA's , back up took lot more time , which resulted in more down time of system . There after slowly we migrated to Documemt management system of SAP which is a proven and standard methodolgy. Why not suggest your customer explaining the pitfalls and go for a DMS way for a longer term approach.

Hi Suresh,

You are correct. we invite all sorts of problems as you mention. We have suggested the client and they might consider after some time but mean while have to live with this.

Appreciate your inputs. Thanks.
