Yes, a Requestor can assign a substitute Requestor. The person being assigned must already be setup as a Requestor.

Please note: although assigning an Approver as a substitute Requestor is possible, it is not recommended because they won’t be able to submit into workflow.

To assign a substitute Requestor: Navigate to Shop => My Carts and Orders => View Carts => Assigned Carts tab => click Assign Substitute => follow the prompts.

To remove an assigned substitute Requestor: Navigate to Shop => My Carts and Orders => View Carts => Assigned Carts tab => click End Substitution.
