Change a PTA on an Approved Purchase Order

This page provides instructions for how to change a PTA (Project, Task, Award) on an approved purchase order (PO). The process of changing PTAs can be completed by Oracle users in the Requisition and Purchase Orders Query tool and will change the PTA(s) to pay future invoices by the changed PTA line. PTA changes do not affect already paid invoices, please use iJournals to change the PTAE on past and pending payments. For more information, see How To: Create iJournals Entries.

If you need to change the Expenditure Type or add funds to the PO, submit a Standard Change Order. See How To: Change a Standard Non-Catalog Purchase Order (Create Change Order) for more information.

Change a PTA on an Approved Purchase Order

  • The PTA Change process begins by searching for and retrieving a specific purchase order in the Requisition and Purchase Orders Query tool. The following buttons may display, in the upper right of the PO Details section, if specific criteria are met:
    • Change PTA: This PO is eligible to have one or more PTAs changed
    • Review Ineligibility to Change PTA: This PO is not eligible for PTA changes (Select this button to see why the PO is not eligible for a PTA Change.)
  • Preparers can change multiple PTAs on POs with multiple lines. However, the option of splitting a charge from one PTA into multiple PTAs is not available. 
  • The replacement PTA(s) must be currently valid for this type of expense (not closed or on-hold). For more information on valid PTAs, see, Purchase Order Invoice Processing.

NOTE: To change the PTA on any Subaward Purchase Orders, the preparer/Principal Investigator must contact the Subaward Resources.

PO Eligibility to change PTAs 

When the PO is eligible for PTA change(s), the Change PTA button will display in Requisitions and PO Query when the PO:

  • Has had no invoice activity. In this case, the requester can change the PTA for all future invoices. 
  • Has pending invoices with a “no hold” status and there are funds remaining on the PO. The PTA change(s) will only apply to future invoices with a “no hold” status. If the invoice is already paid, use iJournals to transfer the expense to the correct PTA(E).

The Review Ineligibility to Change PTA button will display, if the PO is ineligible for a PTA change and the PO:

  • Has pending invoices with anon holdstatus. To change a PTA on a PO for any amount that has invoices with an “on hold” status, please submit a change order requisition
  • Has a quantity (not amount) that is fully matched on an invoice with a no hold status and there are no funds remaining on the PO.
    In this case, funds need to be added to the PO through a change order requisition.
  • Has been Finally Closed.
Obtaining Approval for PTA Change

For POs with a total remaining commitment amount above $1,000, approval is required. The tool will populate the new PTA’s current approval workflow. The tool also provides the ability to add more approvers and FYI recipients. Approval is not required for POs with a total remaining commitment amount of $1,000 or less, but users will have an option to include approver(s) as desired.
