Dump DYNPRO_MSG_IN_HELP on F4 help for file selection
While processing the “F4” of the file selection using cl_gui_frontend_services=>file_open_dialog, if the user selects nothing and chooses the cancel button, we always want to give a message at this time.
Please don’t try to output an “E” message at your program; otherwise, it will trigger the dump error ‘DYNPRO_MSG_IN_HELP’ with the category ‘Error at Screen Runtime’. Instead of the Error message, just change to the ‘S’ type will do and stop further processing.
Take this as a template backup for file selection : )
