How does incremental freight invoice work when invoicing for a single counterparty with multiple cargoes?

If you have:

• Multiple cargoes with the same counterparty on one voyage

• Previously issued freight invoices for all the cargoes, and

• Made a change on one of the cargoes that would change the invoice amount for that cargo.

Creating an incremental freight invoice for the above scenario will reverse all previously invoiced items for the counterparty, even for the other cargoes that you did not make changes to, and then recalculates the overall freight value. The reason for this behaviour is that the Freight invoice is issued against the counterparty regardless of how many cargo grades have been loaded.
