I would like to revive this thread and support the OP’s request for the ability to be able to select the “Foreign exchange gains (losses)” account in Journal Entries to enable the ability to allocate to a project and/or division, or to transfer to more specific income or expense account.
I realise that the value shown in this account in reports contains both realised and unrealised gains/losses and is the reason that it is not currently possible.
However, is it possible to have a separate gains/losses account for transactions that have been completed and the gain/loss will not change (realised gains) which can be made available in Journal Entries and a separate gains/losses account for those assessed on the date of the report (unrealised gains) which would not be available in Journal Entries?
This also relates to this thread which is categorised as an idea.
