AP fulfiller uses the purchase order line mapping skill to automatically map the invoice lines with the purchase order lines.

## Before you begin

Role required: admin

## Procedure

1. Activate the purchase order line mapping skill.
2. Navigate to AllAccounts Payable OperationsProperties.  
   The Now Assist skill evaluates and executes rules on the invoice lines and performs the invoice line mapping with purchase order line mapping. For more information on setting APO properties, see [Set APO properties](https://servicenow-prod.fluidtopics.net/bb5oYXl2Pb~v2VC7v8ETOw "Use the APO properties form to set the parameters that control the invoice line mapping, invoice ingestion API and exception management."). In the playbook, the match lines card allows you to review the mapping performed by Now Assist. For more information on the match lines card, see step 7 of [Using Playbook in Accounts Payable Operations](https://servicenow-prod.fluidtopics.net/oYdvUiEvC4neeZ8p5VyUzA "Configure a playbook and visualize the step-by-step actions performed by an Accounts Payable specialist while processing an invoice.").
