The Approver is an accountable decision maker who is responsible for rejecting or approving new assets of changes to published assets. The Approve action advances the asset to the Approved status. The Reject action returns the asset to the Draft status.
The approval activity is a part of the workflow process by default. The Administrator can disable it by setting the Allow approval of terms to No, specify Number of required Approvers necessary to and enable and configure the approval activity to progress automatically to the approval activity when the required number of recommendations is reached. You can disable the automatic progression by setting the number to 0. In this case, the Editor is responsible to tally the review results and submit the asset for approval then it is appropriate.
