Abstract

A communication apparatus includes a first reception unit which receives an instruction from a server, a second reception unit which receives an instruction from a path other than the server, an executing unit which executes a function when the first reception unit receives a first execution instruction from the server or when the second reception unit receives a second execution instruction from the path other than the server, and a display control unit which displays a display instruction correspondence screen when the first reception unit receives a display instruction from the server, and which displays an execution correspondence screen when the executing unit executes the function. During a time period while the display instruction correspondence screen is being displayed, the display control unit displays the execution correspondence screen when receiving the first execution instruction, but doesn'"'"'t display the execution correspondence screen when receiving the second execution instruction.
