[Koha] Help to simulate late orders in Koha

[Vimal Laxman]

Dear All,
                 I am trying to simulate late orders for a demonstration of
koha late orders and mail genration to vendors.I created a basket with two
book orderd .I even predated the order by changing the creation date
(edited in the database wherever applicable).I have set the estimated
delivery time for the  vendor as one day. But i am unable to see any late
orders in the menu.can any body let me know how i can simulate late orders
and also check if i can send mails to the vendor for claims (i have already
configured send mail).

Regards,
Vimal
