Step1. cl_gui_frontend_services=>execute method can be used to call any URL. It can be used to call any webdynpro/fpm application from the program as every webdynpro/fpm application have an uniuqe URL.

Step2. Here it calls the URL.

Step3. Still we can open any document by specifying the appropriate executable file, location of the directory of the file and providing the file name.
