If the product is in stock still look up the stock item and head to the Components tab. There will be a link to the “BULK” wine. Click that to take yourself back to the wine itself – a historic placeholder for it at least.
Alternatively if the wine has been dispatched, to get to that same place, go to Search -> Dispatch search and find the dispatch of the product before selecting it and clicking View wine details.
From here you can get back to the Relevant history of the wines. You can also run reports such as the label integrity report or the status report available under the Actions button or the Reports button.
