The function restriction information of a designated flow executor is acquired. The acquired function restriction information is analyzed. An operation screen that identifiably displays process contents executable by the flow executor in association with setting target functions to be set in the flow is displayed on the basis of the analyzed function restriction information. Process contents of a setting target function to be set in the flow are selected on the basis of an operation in the operation screen. The flow of the flow executor is generated by combining the functions of the selected process contents.
