Remarks

The ApprovalActivity activity can be used in the authorization phase to obtain an approval for a submitted Request. (For more information, see Request Processing). The activity creates an Approval instance that is associated with the approval activity. If a valid approver rejects a request before the ApprovalActivity is completed, the approval immediately fails, and the workflow and associated request are terminated.

After an Approval instance is created, the approval activity continues only until the minimum number of approval responses is met, as specified by Threshold. After the threshold is met, the ApprovalActivity recomputes the list of approvers and verifies that each ApprovalResponse is valid.

When the ApprovalActivity activity starts, if any approvers that are defined in the Approvers field do not exist, or a parameter lookup is not valid (based on the workflow lookup grammar), an exception is thrown, and the workflow is terminated. If the timeout threshold is reached and no valid escalation is defined, the workflow terminates with a 'Terminated' status and the associated request is denied.

If the requester is also a computer approver, the activity automatically creates an ApprovalResponse instance on behalf of the requester. This behavior enables approval activities that have thresholds of 1 to auto-approve themselves.
