Delegated approvers for approval requests
Key Takeaway
In a Flow Approval Process, the delegate named in an approver's Delegated Approver field can approve or reject a work item just like the assigned approver. Classic Approval Processes add a step-level condition.
A delegated approver, or delegate, is an alternate person that an assigned approver appoints to act on their approval requests. In Flow Approval Processes, the delegate gets the work item notifications and can approve or reject the work item. Classic Approval Processes also support delegates.
What a delegate can do
When an approval step runs in a Flow Approval Process, it creates an approval work item for a user, group, or queue. If an assigned approver has a defined delegate, either person can complete the work item. So the delegate can approve or reject a work item that is assigned to the approver.
Classic Approval Processes add a condition: the step must have "The approver's delegate may also approve this request" enabled before the delegate can complete a request. Delegates in Classic Approval Processes can only approve or reject requests, not reassign them.
