Error in outbound delivery creation for STO

Hi All,

I have created a NB type stock transport order. Now I want to create an outbound delivery against it. But when I go to Txn VL10B I get an error as

No schedule lines due for delivery up to the selected date

Detail

Diagnosis

There are no schedule lines due for the given order item up

to the date chosen.

System Response

The system does not create a delivery item for this order

item.

Procedure

o Check whether the order item to be delivered contains

confirmed schedule lines.

If this is the case, set the selection date further into

the future if you still want to create a delivery for this

item.

Could someone plz let me knwo what am I missing?

Regards,

V S
