Hi all,

In my first blog on SCN I want to show some tricky stuff to get the thumbnail image data and show up in a Dynpro.


In every ERP system is a document storage involved. But for this example I want to show how to get the image data out of a external storage. There are different description for it and maybe I mixed it up: content server, KPRO (knowledge provider)

SAP menu –> Logistics –> Project System –> Documents –> Document Management System –> Document:

  • CV01N, … , CV04N

The bad thing for a external storage is that the ERP system doesn’t get the image data directly, if you call up an original, it just send the Link-address from the content server to the client (SAP Gui). There is no (image)data transfer between ERP and the client.

So the key is to get the link URL and show this thumbnail in a dynpro. I suppose that the customizing is set up correctly with a defined Thumbnail (small picture) WS-application.
Well there is a function CL_DMS_THUMBNAIL_DISPLAY=>GET_URL to catch the URL for the selected document number.
The next thing is to set up an custom container in a dynpro screen create the objects and show up the image data to it.

The thumbnail will be shown in the same height and width what the custom container has in your dynpro.

The complete  code with additional pictures is available here:


–> code snip – begin

DATA: gv_url       TYPE dms_url,
         gs_doc       TYPE bapi_doc_keys,
         gr_thumbnail TYPE REF TO cl_gui_custom_container,
         gr_picture   TYPE REF TO cl_gui_picture.


  CALL METHOD cl_dms_thumbnail_display=>get_url
       EXPORTING i_doc = gs_doc
       IMPORTING e_url = gv_url.


     CREATE OBJECT gr_thumbnail
            EXPORTING container_name = ‘CV_THUMBNAIL’.

     CREATE OBJECT gr_picture
            EXPORTING parent = gr_thumbnail.

     CALL METHOD gr_picture->set_display_mode
          EXPORTING display_mode = gr_picture->display_mode_fit_center.

     gr_picture->load_picture_from_url_async( url = gv_url ).


–> code snip – end 


My next quest is to show up such thumbnails into print forms (Adobe Interactive Forms, Smartforms, SAP Script) and put it out on printers. If you have useful hints please write it down in the comments or extend the wiki page. Thanks!

    Actually this URL basically works like a REST based Web Service.  You can call the URL and the response body is the image data.  You can get the data into ABAP memory using the CL_HTTP_CLIENT class.  This class allows you to make HTTP Requests directly from ABAP.

    Once you have the image content in memory on ABAP you can do all sorts of interesting things.  I have written programs in the past to send the image data to the IGS to do image format conversions or done direct manipulation on the image at the byte level in ABAP directly (rotation, inversion, etc).

      Hi Thomas,

      thanks for your comment!

      If my testsystem is ready again on monday (finally with EHP3) 🙂 I’ll test it.

      I remember the image processing thing which was initialized by Blag 🙂 and now found additional weblogs for this class on sdn by you.

      Hopefully it brings me one step forward to print originals on paper…

      Thanks so much

      Hi Thomas,
      I tried out what you said, but the problem is that the URL I’ll get by the CL_DMS_THUMBNAIL_DISPLAY=>GET_URL is not an “http” one. It is something like that:
      SAPR3://SAPR3CMS/get/100/ZCS_5FTEST_5FSYSTEM_5F100/7DC37D4857B78E7DE1000000AC138504/216_5FKL_5FED.jpg (I’m able to follow this link on the harddrive of the content server [the ‘5F’ seem to be some escape characters])
      And I didn’t found a why to create a valid HTTP link out of this.
      What I found out is that the string (7DC37D4857B78E7DE1000000AC138504) is the document id which is coded and in SAP somethin like that ‘21100396’
      Do you have more helpful suggestions?
      Thanks, Steffen

        I would look at the internal processing of cl_dms_thumbnail_display=>get_url.  The SAPR3 URL protocol is specific to the SAPGUI HTML control and is a way to tell the SAPGUI to read the data via the control framework. If you are using the content/cache server, however, there is ultimately an HTTP based interface as well and documents can be received via HTTP.  You may find inside this processing of this class that the work to read the data via HTTP is already being done and the content is being placed inside a CFW DataProvider.

    have you succeeded in printing thumbnail pictures in smartforms or is there is a way to print contents of dynpro container , as we have got some textual or pictorial info in 2 different containers present in single dynpro screen.
