@karl1234: The first of your transactions has a payment and receipt and hence there is an exchange rate variance computed on the exchange rates used (one for payment and another for receipt) for the nett balance of the transaction set. In your second transaction, there is only a notional value in the exchange rate variance account as it awaits the contra entry when settlement occurs in the desired currency.

@andijani: The second transaction (one way) of @karl1234 applies to both your transactions.

Here are the results for the same entries in both FA 2.3.22 and FA 2.4.3

Bank Payment     1015     BP0391     03/29/2018         165.90     TST Inspection     (this is USD)

Accounting entries (All numbers are in CAD):

FA 2.3.22
Bank Payment     1015     03/29/2018           TST Inspection               217.33    
Journal Entry     173             03/29/2018           TST Inspection     344.20              Exchange Variance

FA 2.4.3
Bank Payment     1016     03/29/2018                                                  217.33         
Journal Entry     87             03/29/2018                               171,300.56                     Exchange Variance

The balances in foreign currency accounts are way off especially in FA 2.4.3 and in each case the Bank Payment or Deposit were involved.

Now when i do a fund trasfer from a EUR to GBP bank account or even a GBP to GBP bank account I get a FundTranfer which seems 100% and then I get an additional journal entry with a value that always is doubling.

Please see example

Fund Transfer 105

Journal Entry 117

Any ideas.  I personally don't see the reason for the journal entry at all. 

Using version 2.4.2.
