the scenario is about flight reservation system.the screen is having fields like departure city , departure_airport . i m creating F4 help on departture_airport but before i press F4 on this filed assume that i have already entered the the departure city. so this is where my requirement is ,when i press F4 on departure_airport it gives me the default selction screen provided by SAP having departure city to be entered . NOW i want watever citty i enter in the departurecity field should appear bydefault on the standard selection screen when i press F4 on the departure_airports . Is it possible ? if yes then how ?
Thanks in advance .
