I have just tested a bit and here is what I got in the demo:
http://www.weberp.org/weberp/GLTransInqu...TransNo=43
I have also narrowed it down in my system - it is happening once I click Process Allocation (CustomerAllocations.php)
The journal in the above example resulted on the receipt value moved into exchange account:
Date Period GL Account Debits Credits Description Posted
05/04/2013 April 2013 Petty Cash 1,646.21 No
05/04/2013 April 2013 Accounts Receivable FXBUG 1,646.21 No
05/04/2013 April 2013 Sales Exchange Gains/Losses 1,646.21 No
05/04/2013 April 2013 Accounts Receivable FXBUG 1,646.21 No
If you could have a look into this would be much appreciated.
Thanks
