When purchase invoices are entered as quick entries, the reference field appears in the "Our Ref" column when a remittance is printed. There is no way to get anything to appear in the "Your Ref" column from a quick entry.
We use the details field of quick entries to record the suppliers invoice numbers. It would therefore be useful to to have a feature which allowed the details field to appear in the "Your Ref" column of the remittance so that suppliers can see their invoice numbers. If we try and get around this problem by putting the supplier invoice number in the quick entry reference field the remittance doesn't make sense because the supplier invoice number appears in the "Our Ref" column.
