User Accidentally Cancelled PO With Cancel Unfulfilled Demand = No

Our user accidentally cancelled a Project PO without changing the Cancel Unfulfilled Demand to YES. This should have been updated to YES so the project funds were released back to the project. Now we cannot take action on the cancelled PO and the PO is not listed in Manage Committed Costs in the Project Costs work area. The user tried to create a new PO for this requisition, but it is failing a funds check because the original canceled PO amount is being included in the budget consumption. Is there any way to release this project budget amount back to
