What is a change Order? When do we need to perform this action?

As a buyer you may send a change order to adjust a previously placed Purchase Order (PO).

• A change order generates a new version to the existing Purchase Requisition (PR).
• A new order version is created when changes are made on the line items of the requisition.
• The new PO will display a higher version number, but its order number will remain identical to the original number.
• If there is a change made on the splitter fields within the line, then the old order will be canceled and a new one will be created in place of this.
• This is updated in the requisition history.

Even if the original PO had already been confirmed, shipped, or serviced; a new order confirmation, ship notice, or service entry sheet should be created for the new version of the order as required.

Change orders do not inflate your account's document count for the purposes of SMP billing. Regardless of the number of versions uploaded, a specific PO number is considered to be one document.
