Unable to create delivery

Dear Friends

I am unable to create an outbound delivery for an order.

The error message number is VL461

Error message is "Order cannot be delivered.".

Diagnosis

Possible reasons include:

o The copy conditions specified in Specify copy control for deliveries

do not allow the order to be delivered.

o The order is blocked for delivery.

o The order document is incomplete.

Any help/guidance will surely be appreciated.
