Payment of Purchase Invoice with a landed cost voucher

I have created a purchase Invoice but i also created a landed cost voucher to account for the additional expenses on the purchase, but when making payment the invoice amount is unchanged and does not include the additional expenses that were added by the landed vost voucher.
Can you please help me on how i can proceed with making the payment of the invoice that has a landed cost voucher

Landed Cost Voucher will only affect the valuation of the item being received.

For the amount you’re paying for landed cost, you can create a separate invoice.

Can you share more about this case? Is the landed cost you incurred being paid to a separate entity apart from the supplier?
