Use PO number from invoice header

When the option is disabled, SEMINE searches for the PO number in the standard field.

• cac:OrderReference/cbc:ID

When this option is enabled, SEMINE also checks if the following fields contain one of the PO numbers.

• cbc:BuyerReference
• cbc:Note

How it works

For the cbc:Note field, SEMINE normalizes both the extracted PO number and the purchase order number before comparing them. This improves matching when PO numbers are written with different formatting.

Example

Invoice header text	Matched PO number
Invoice contains the PO number PO-1234	PO1234
PO - 1/23.456	PO123456

Note: The same PO matching logic is applied regardless of whether the purchase order or the invoice arrives first.
