I just noticed something a bit odd.
I was creating a custom report on Bank lodgements when I spotted some entries being doubled up. Further investigation shows that if you book a receipt to Account Receivables / Customer without specifying the invoice number the G/L transactions seem to include an unnecessary debit & credit transaction.
This is the Bank Receipt transaction and then custom G/L report
But if you specify the invoice, then you only get one debit & credit entry
The G/L transactions report only shows one debit & credit in all cases
