To execute coordination processing after the occurrence of an error so that a user's requirement may be satisfied when the error occurs during job flow processing.
A coordination processing server 50 determines that the error occurs to an image processor 62 when the above server receives the result of processing the error from the image processor 62 or does not receive any result on the processing from the image processor 62 after a prescribed period of time elapses, after the server requests the image processor 62 to execute a second service processing. Then, the coordination processing server 50 excludes the already executed service from "Execution" and generates a new instruction document to which an instruction document at the time of the occurrence of the error is attached as "Log".
