Using the transaction launcher to call a BOR method to display a PDF

Question

Hello gurus,
I have created a PDF icon and an onclick action to open a pdf, that displays on every row of an assignment block in the actions column, but I do not know the technical process to determine how to get a PDF from the IXOS system from the line selected. (even if I know it depends on an ID attribute of that assignment block) I want to to call a transaction launcher with the url for the pdf in the IXOS that has an ID that identifies which line in the assignment block the user has clicked the pdf icon for (does that make sense?)
In CRM 4, in the collection factsheet assignment block, the link was coded into an XSLT which is then displayed in the GUI and you would have a clickable link for a pdf file in a row in a table. That link would be as follows:
         <xsl:variable name="ev_key">SAPEVENT:?OBJTYPE=<xsl:value-of select="attributes/OBJTYPE"/>&amp;OBJKEY=<xsl:value-of select="@KEY"/>&amp;LOGSYS=<xsl:value-of select="attributes/LOGSYS"/></xsl:variable>
             <a href="{$ev_key}"></a>
This will get the file in IXOS and display it, in CRM 4. In CRM 7, the link is an icon in every line of an assignment block.
Here are some questions I have now for the functional side in the meantime:
1) Can we fetch the PDF in IXOS for each line of an assignment block and have it open? If so, how? Transaction launcher, function modules (like ARCHIVOBJECT_DISPLAY) in the OPTA package? (the package for all IXOS related function modules..)
2) Which URL should I call with the transaction launcher? a URL link to the PDF on the IXOS system?? or sapevent:xxx?
3) Do we have to configure a transaction in the IMG to be launched with the attributes listed there? Do we have to link it to any classes/ objects?
4) Do we have to have the code to the logical link dynamically to call the right PDF for each table line? Is it right to put this code in my event handler?? Usually transaction launchers are just in the nav bar.....
5) Are there any existing examples of this or a similar functionality/ logic that I could refer to, preferably in CRM 7 WebUI?
6) Do you have any code to just display a PDF in a new window? Or prompt a download?
One possible way I thought of would be for me to have a logical link defined in the IMG for the transaction launcher, and have the attributes defined for my BOR object that I would call, and pass it different attributes (eg. objtype, objkey, logsys...) and then return the PDF and display it in the UI in a new browser window by itself. (There is a BOR method for my BOR object named  'display_pdf'!!!!)
What do you think would be the optimal solution here? Does my theory of calling a BOR object with a transaction launcher to display a PDF make ANY sense whatsoever???
Please do not hesitate to propose any potential solution. Any partial answers/ links to wikis/ other threads, anything would be much appreciated.
Thank you in advance.
Best regards,

Answer 1

Hi Any help on this....I am still awaiting the response.
Requirement: My requirement is to launch the SE38 transaction on WEBUI using transaction luncher tool and set the parameter on the selection screen.
Issue: The issue is that I am able to lunch the transaction but unable to set the parameter
Steps Performed:
I want to list down all the steps I performed to launch an SE38 transaction using transaction launcher on the WEBUI
1) Defined logical system in tcode CRMS_IC_CROSS_SYS
-The logical link looks like this
http://<server>:<port>/sap/bc/gui/sap/its/webgui/!?transaction=IC_LTXE&okcode=ICEXECUTE ?sap-client=300
2) Defined URL & paratemeter wherein the request method is "GET", opted for NON-BSP URL
URL link here is
http://<server>:<port>/sap/bc/gui/sap/its/webgui/!?transaction=SE38&okcode=ONLI
-Note: My selection screen okcode os ONLI*
-The logical system ref is provided here
3) Defined the parameter by giving the screen name like for SE38 selection screen name is "RS38M-PROGRAMM"
4) Configured the transaction launcher of type B - URL type and provided the reference of the URL ID, choose the relevant parameter from the drop down and have hardcoded the value, cheked the box "Save Data in Activity Clipboard
5) Added this in the NAvlink/Bus Role etc
6) Now in the handler class of the TL the code looks like this:
IF_CRM_IC_ACTION_HANDLER~PREPARE_DATA_FLOW
__gdc ?=
cl_crm_ui_data_context_srv=>get_instance( gv_view_controller ).
__value
=
'ZC_TEST'.
add_parameter(
   iv_name =
'RS38M-PROGRAMM'
iv_value = __value ).
However, after performing the above steps I am unable to set the parameter. Please suggest where am I missing out on. An early response would really be appreciated.
