Nominal transaction Enquiry - Purchase ledger 2nd Reference should be available within this screen

There should be a display of 2nd reference within nominal ledger transaction enquiry. Even if you double click on an individual transaction within nominal ledger the different tab options (bank, VAT trader trans, etc) does not list the 2nd reference. We use the second reference to store our internal number purchase invoice number. We store our invoices in in numerical order (which is the 2nd reference). This would make it easier to retrieve our internal purchase invoice number quicker. The only way we can do this now is come out of nominal ledger, go into purchase ledger and look for the the 2nd reference that is linked to the reference (the 3rd party purchase invoice reference).
