AR AP Netting - What is created in Payables as a result of netting

Hi,

I've seen that a netting payment is created when nettting has been run. However, how is that reflected on the original AP transactions? E.g AP invoice of 100 ans AR Invoice of 50 are netted. How is the netting reflected in AP? Is there a payment of 50 applied to the AP invoice and, if so, how is it recorded that this was the result of netting?

Many thanks

Mary.
