Returns delivery(STO) not picked up into Shipment

Hello Experts,

I have been working on trying to configure the returns STO process for shipment.

the returns delivery type is NCR. so I have done the settings like:

1. made NCR relevant for transport.

2. Delivery item category relevant for transport,

3. route relevant for transport.

But I am unable to see the returns delivery in VT01N tcode. The shipment document type used is 0002-Inbound shipment. And the route is already maintained.

So, can anyone help me out on this as where exactly I am missing out and what more settings to be done so that I can do Shipment for the returns delivery...

Regards,
