A provider ID is stored in a mixer configuration or custom component supplied by the provider. If a logging-on user is a provider user, when his/her provider ID matches a provider ID in processing target data, the relevant provider user is permitted to display/edit the relevant mixer configuration or custom component. If a logging-on user is a general user, the general user is authorized within a range allowable in provider protect contents. COPYRIGHT: (C)2006,JPO&NCIPI |
