How to Invoice the adjusted charges on the PO Invoice ?

Hi,
In AX 2012 Purchase Order life cycle, if we want to add some misc. charges after the PO get invoiced, we can use “Invoice Journals” > Adjustment Form, if we want to invoice these charges to vendor, what is the way to adjust charges in invoice?
let’s say, I received some charges from cargo after posting the PO Invoice. how can I pay these charges to the cargo or i have to pay to vendor itself, how to add the additional charges.
in the AP Payment proposal doesn’t add the “Adjustment charges” to the “invoice voucher” form
Thanks,
