A company has as accounting currency SEK but they are located in UK, so the VAT needs to be reported in GBP, vendors are sending an invoice on SEK currency but specifying what the exact VAT in GBP they are calculating, the problem in D365 is that in this case we don't have an exachange rate, since the transaction currency and the accounting currency is the same; the VAT is getting calcualted using the "default" exachange rate but we should be able to specify the rate we need for the specific transaction.
