Learn how to add taxes from Tax Determination to a single- or multiple-line Accounts Payable (AP) invoice that matches an existing purchase order.

1. Go to Payables > Invoices.
2. Click the Tasks icon, then click Create Invoices in the Invoices section.
3. On the Create Invoice page, go to the Invoice Header section.
4. In the Identifying PO field, enter the purchase order number and select the corresponding option from the dropdown.
   The fields are automatically populated with information from the purchase order. Make sure all required fields are filled in. Required fields are marked with asterisks.
5. Expand the Lines section and click the arrow next to the dropdown.
   Because you are working from an existing purchase order, the dropdown automatically shows the Match Invoice Lines option.
6. In the Match Invoice Lines pop-up, select the lines you want to include in the invoice.
7. Click Apply, then click OK.
8. In the Lines section, check if the information was applied to the lines correctly.
   Note:

   When adding multiple lines, you can set different ship-to locations for each line item.

9. Click the Refresh button.
   You may get a warning if the supplier, invoice date, amount, and currency match the values in another invoice. The warning indicates that you are invoicing items from a purchase order that was already invoiced.
   • If the information is correct, select Continue.
   • If the information is duplicated, select Review Later or close the warning and adjust the invoice accordingly.
10. In the header, click Invoice Action and select Validate from the dropdown.
    The invoice status is now Validated.
