ABSTRACT:
A check-out document cannot be updated by another operator unless an operator who checked out that document cancels the check-out status or checks in the document. To remove this inconvenience, document data is set in an exclusive state with respect to another user, and a password required to cancel the exclusive state is generated. The exclusive state of the document data is canceled based on an instruction of a user who instructed the exclusive state or an instruction of the other user with the password, thus updating the document data.
