Call SAP GUI txn from WD4A running in the SAP GUI

[Former Member]

I'm somewhat new to Web Dynpro and I'm trying to evaluate the use of WD4A as our main custom screen/txn platform. I have written a simple application. I created a transaction code that calls WDYID and launches my WD4A application in the SAP GUI.

Our company does a lot of "CALL TRANSACTION" in our normal dynpro development and I need to prove out that it is possible to do the same in WD4A. I've used the following code to try and call a transaction:

  CALL METHOD lo_window_manager->create_external_window
    EXPORTING
      url           =
'http://<host>:<port>/sap/bc/gui/sap/its/webgui?sap-client=<client>&~TRANSACTION=VA03'
     title          = 'Display Orderl'
*    MODAL          = ABAP_FALSE
*    HAS_MENUBAR    = ABAP_TRUE
*    IS_RESIZABLE   = ABAP_TRUE
*    HAS_SCROLLBARS = ABAP_TRUE
*    HAS_STATUSBAR  = ABAP_TRUE
*    HAS_TOOLBAR    = ABAP_TRUE
*    HAS_LOCATION   = ABAP_TRUE
    RECEIVING
      window         = lo_wd_window.

The problem with this is that when called from the SAP GUI, it launches a browser. I would like for it to go directly to the WebGUI version of VA03.

Is this possible?

Finally got a note applied and tried to do a suspend call to an ITS app. The call itself worked, however, my resume isn't working. After I hit back on the ITS app it just goes back to the SAP menu.

I added a resume type plug to my inbound plugs. Does there need to be code in the resume plug? I think maybe I'm missing something.

So the exit url worked too. However, it ends my current WD application. When I try to call VA03 using a suspend plug, it throws and error saying I have invalid characters. Are suspend plugs only for calling other WD applications?

Hi Adam,

you should be able to suspend to an ITS call.

- however you might fall foul of a bug - fixed in note 1255292 (Special characters not permitted for suspend/redirect)

Not sure if this is what is causing the issue...

Can you not pass parameters to the transaction using the CL_WDR_SAPGUI_INTEGRATION2->FIRE method?

this is what is called by the FIRE_START_TRANSACTION method, but allows for additional parameters.(I've never used it myself so I'm not sure that it would work, but would be interesting to find out - could you let us know?)

Cheers,

Chris

I created an instance of the sap_gui_manager and calling a transaction and that worked like a charm. Doesn't look like there is a way to pass parameters though. I'll try the URL to the outbound plug. Thanks for the help!

Adam,

You could instead of launching an external window fire the exit plug of your application and pass the ITS URL to the exit plug - this will then launch the ITS session in the current browser - exiting the current application.

(search on exit plugs url - you will find many references).

Hope that helps,

Chris
