Once a delivery or invoice has been added to a purchase order (PO), certain fields become locked. This is by design to maintain the integrity of the 3-way match between what was ordered, delivered, and invoiced.

What You Cannot Edit

For a PO that has a delivery or invoice attached, you cannot edit the following details:

• The supplier
• Existing items on the PO, including their price or quantity

What You Can Edit

You can still edit a wide range of other details on the PO, including:

• PO Title
• Currency
• Due Date
• Department
• Delivery Address and Date
• Project
• GL Account
• Any custom fields
• Cost fields
• Payment terms
• Terms and conditions
• Required documents
• Additional notes
• You can also add new line items to the PO (and edit their price and quantity)

How to Make Changes to Locked Fields

If you need to change a locked field, you must first delete the associated delivery or invoice. Once the related records are removed, the purchase order can be fully edited.
