When can I edit the Unit Price field on a change order?

In the default configuration, you can edit the price and quantity if the purchase order has not been received or shipped (Ordered status).

After the requisition moves to Receiving or Received statuses or after your supplier sends a ship notice for the order, you can no longer change the price on a change order.

Contact SAP Support if you want to allow users to change the unit price regardless of the receiving status of the order.

There are two parameters that control whether users can edit the unit price on a change order:

• Application.Procure.AllowEditingOfUnitPrice: Specifies whether editing the unit price of line items in partially or fully received purchase orders is allowed. When set to Yes, only members of the Purchasing Agent group can edit the unit price of line items in partially or fully received purchase orders.
  
  
• Application.Procure.AllowAllUsersToEditUnitPrice: Specifies whether users can edit the unit price of line items on partially or fully received purchase orders, even if they do not belong to the Purchasing Agent group. This parameter is effective only if the Application.Procure.AllowEditingOfUnitPrice parameter is enabled.
