R3 Transaction CV04N; process first screen

Question

Hello all,
I'm using URLGenerator to generate a URL for the transaction CV04N. I supply params and get the URL no problem and display it in the portal.
I can't process the first screen though, it always gets displayed. Here is the important part of the code that I'm using.
// Generate our URL to run transaction ZVAN
IUrlGeneratorService urlGen = (IUrlGeneratorService)PortalRuntime.getRuntimeResources().getService(IUrlGeneratorService.KEY);
ISAPUrlGenerator transGen = null;
ISpecializedUrlGenerator specURL = urlGen.getSpecializedUrlGenerator(ISAPUrlGenerator.KEY);
if(specURL instanceof ISAPUrlGenerator){
     transGen = (ISAPUrlGenerator)specURL;
     try{
         String transURL = transGen.generateTransactionUrl(request,
           sapSystem,
           "CV04N",     // Transaction code
           "STDOKAR-LOW=DMO&STDKTXT-LOW=*TEST*", // Parameter list
           "WinGui",     // GUI type
           true,          // Process first screen
           false);     // Uses transaction SP01
// We use JavaScript to display the transaction in the window
        myForm.addRawText("<script>window.location='"+transURL+"';</script>");
    }catch(Exception e){
        gl.addText(1, 1, "Unable to generate transaction URL");
        gl.addText(2, 1, e.toString());
}else{
    gl.addText(1, 1, "Not instanceof ISAPUrlGenerator");
the transaction is called with and the parameters are there in the appropriate fields, but the initial screen always shows. How can I process the initial screen of this transaction?
Regards,
Patrick.

Hi,
You can pass values to Transaction through the property "Parameters Forwarded To Transaction".
But if you want to set the parameter values dynamically, then you have to do a little customisation. You can develop a webdynpro application where you can write the logic for dynamically setting the parameter and call the transaction iview through WDPortalNavigation.navigateAbsolute and set the dynamic value there.
Thanks
