Hi there, could so explain what is "Show shopping date" parameter in invoices configuration, and how it works?

I want to know too or how can add custom date from product in virtuemart and show it in invoice

Hello,
AFAIK, there is nothing like "shopping date". There is only "shipping date" if you mean that?
(and that is - as possible to see from tooltip over the option - the date of last change of the order status to Shipped status)

to vismapro)
Custom date from a product in VM? What should that be, can you give an example, please?

Yes sorry for the mistake Jan, i meant "Shipping" as in my topic's title. OK i got it now, thank you very much for your help. Is it possible to display this info only on the delivery note... ?

Yes, by editing the invoice template and removing it from there or setting it not to show for invoice.
