# Amend Purchase Orders - Old DPO Design

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.

||| **Already using DPO's new design?** [You can find the corresponding article here](https://help.digitalpurchaseorder.com/en/article/amend-purchase-orders-in-dpo-7xfy29/)

### 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](https://digital-purchase-order.crisp.help/en/article/bypass-approval-levels-bypass-function-1cbvnv6/)
* 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.

**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
