Web Dynpros -- possible to call a SAPGUI operation?

Question

We're developing an Web Dynpro application in which it would be appropriate to invoke a "SAPGUI" operation, such as a TCode (ex., SE09), a call dialog, or a function module which displays a useful pop-up.
Is this possible from a Web Dynpro?
Our attempts this are permitted syntactically but fail at runtime with "Screen output without connection to user."
BTW - We're working with Web Dynpro for ABAP, but I'd imagine that the same restriction would apply to Java web dynpros, too, correct?

Hi Dreibelbis ,
you can look into creating Transaction Iview in EP. then call this transaction Iview in Webdynpro using WDPortalNavigation.
I can give you the Reference for creating Transaction Iview in EP.

Accessing Transaction Iview in Webdynpro.
WDPortalNavigation.navigateAbsolute(
                          "ROLES://portal_content/TestDir/test2/AIC_Test222",
                          WDPortalNavigationMode.SHOW_EXTERNAL,
                          (String) null,
                          (String) null,
                          WDPortalNavigationHistoryMode.NO_DUPLICATIONS,
                          (String) null,
                          (String) null,
                          "P_BNKLND="BankCountry"&P_BNKKEY="BakKey"&P_ACNUM="accountNo"&P_XSIMUL= ");
There are many Logs available for Creating and accessing Transaction Iviews in Webdynpro. you can have a look .
