In the employee record under the human resource tab, we can set the Purchase Approver. If we set Purchas Approver in the employee record then the approval is done by the selected employee. If no approver is selected then the supervisor “Approves” the Purchase Order.
If a purchase approver is selected then the supervisor is no longer part of the approval hierarchy.
When we create purchase orders from the sales order without selecting the employee from the employee field (employee field id empty) then the purchase order approval doesn’t go through the process and directly moves to the status Pending Receipt.
The purchase approval is processed only if there is a name in the employee field of the purchase order otherwise the purchase order is directly moved to Pending Receipt without waiting for Approval.
