If a bank does not add an unique ID to an transaction, duplicates may occur. They are to be marked duplicate and you are advised not to remove them from the system.
It is possible that you find the same transaction twice in the Bank movements section. This may occur if the bank has not provided an unique ID for each transaction while some transaction details may have changed over time.
We advise you to leave the transaction in Fundrbird and ear-mark it as a duplicate. You can do this for any transaction with status “open” and mark it as duplicate by following Administration > Bank movements > [select duplicate transaction] > select “mark as duplicate” in the top right corner of the screen.
If the transaction was already booked, then first use “revert” to un-book and change the status to “open” before marking it as a duplicate. When marked as a duplicate, the transaction will not affect any of the numbers in Fundrbird and it does not have to be removed.
