When using Workflow 2.0 for purchase order approval routing, once a purchase order is created, the approver(s) currently cannot be changed. So, if an approver leaves the company, the purchase order would have to be closed and a new purchase order created to change the approver(s) associated with the purchase order. This results in extra work, and causes any history associated with the original order to be disconnected. Purchase orders should reflect updates to the workflow when approvers are changed.

Thank you for your suggestion. We will consider this functionality for a future release.  

Best regards.
