Invoke SAP GUI from Webdynpro ABAP

Hi All,

I am calling the webdynpro screen (using FM 'WDY_EXECUTE_IN_PLACE') from SAP GUI screen. In the webdynpro screen I have created one button upon clicking the button it should go back to the SAP screen from where I called the webdynpro screen.

Could some tell me how to do this.

Thanks in Advance.
