Amend Purchase Orders

This article explains how to update existing POs in the DPO system. Whether you need to adjust amounts, switch suppliers, or correct information, changes can be made directly in the purchase order. All modifications are automatically tracked and sent back through the approval process.

What is an Amendment?

The Amend Purchase Order feature allows you to make changes to an already created P.O., such as:

Updating quantities
Changing prices
Adjusting delivery dates
Modifying supplier or department information

Good to know:

After a change (amendment), a P.O. does not need to go through the full approval process again. If the Bypass function is enabled, the approval flow can be shortened. This saves time while still ensuring control over modifications. Click here
You can also add attachments at any time. There’s no need to amend a P.O. just to attach additional documents.

Direct edits to P.O.s are not allowed. Every change requires an amendment and a new approval. The original P.O. ID remains the same throughout all revisions.

You don’t see the + icon (Amend) in the P.O.?

Activate the corresponding permission.

If you are not an admin: Contact your DPO Book Administrator to request access

If you are an admin: Navigate to the Admin section and select Users. Open the relevant User Profile, go to Permissions,

enable the Can amend checkbox, and click Save to confirm your changes.

How to Amend a Purchase Order

Navigate to the purchase order you want to amend and open it
In the upper-right corner, click the plus (+) icon to start the amendment process

When the confirmation message appears, confirm to proceed and begin editing the purchase order

You will be redirected to the standard P.O. creation interface, where you can:

Edit existing items
Add new items
Change supplier, department, or custom fields (like Component)

Once you have finished making your changes, click AMEND P.O. # to save the amendment.

The new P.O. revision is created and automatically receives a new unique P.O. ID.

The system will:

Keep the original P.O. ID
Add a revision number (e.g., Revision 1, Revision 2...)

PO Revision History

If a purchase order has been amended multiple times, DPO automatically combines all versions into a single document.

Open the amended P.O. and click the PDF icon to generate one PDF file that includes the latest revision as well as all previous versions, giving you a complete revision history in one place.

PDF Batch - You will find all revisions attached to the P.O
