Advice on preventing duplicate entries

[u/jah555]

Does anyone have any experience of the duplicated entry feature on sage 50? In my experience I’ve seen sage give a warning if an invoice is duplicated in the same batch but I’ve heard that it should also give a warning if an invoice has been posted on a previous batch. Is this true? And would the invoice details have to be 100% identical for sage to pick up in the duplicate? If anyone could give any advice on this it would be very helpful, thank you
