Approval Modes
You configure an approval action to operate in one of the following modes:
Anyone In Anyone mode, a request can be approved or rejected by any single user in the approver group. In this mode, only one user in the group is required to approve or reject the request. This is the default mode.
Everyone In Everyone mode, a request must be approved by all users in the approver group (it does not matter in which order the approvals are obtained). A rejection by any approver in the group causes the request to be rejected.
