A data processing apparatus is configured to receive a selection of a first function and search for one or more devices which has the capability to perform that first function. The apparatus may then receive a selection of the one or more devices for performing that first function and, in conjunction, determine whether the selected device has the capability to execute a second function. The device identification data may be stored. Subsequently, if the selected device is determined to be capable of executing the second function, which is different from the first function selected, and the second function is further selected, the previously selected device may be displayed as having the capability to execute the selected second function. Otherwise, the apparatus does not display the previously selected device as being able to execute the selected second function.
