Reproducing the Issue
You have the option to stop the Approval Process for a Purchase Order.
You can use the button Withdraw from Approval to cancel the approval process for a purchase order that has status In Approval. That means, it has been sent for approval but has not yet been approved. Once you have withdrawn the approval, the purchase order is in status “Rejected” and the approval status is in status "cancelled".
You can send the purchase order again for approval after you have made changes in the fields that are relevant for retriggering of the approval workflow. These fields are, for example: Company Code, Purchasing Organization, Purchasing Group, Currency, Incoterms (Header Level), Plant, Material Group, Total Net Order Value, Outline Agreement.
For more information, see Manage Workflows for Purchase Orders.
