Hello,
Yes, the Intercompany functionality allows intercompany transactions between multiple databases, for example, in different countries/regions, as well as multiple currencies, different charts of accounts, different dimensions, and different item numbering.
Regards your examples 1 and 2
I think that the USD transaction in the child, which is converted to LCY = AUD will be re-valuated into USD in the parent company. So there might be differences in the USD amoutn in child and parent, depending on the actual setup of the currency exchange rates in the different companies. I think there is no logic which compares the amounts in case the currency code is the same in the original transaction and the amount which is received through the IC functionality
Please test this and if you face issues feel free to open a service request at Microsoft / ask your BC partner to open a service request on your behalf.
