I have created a drop ship sales order and from that I created a purchase order.

I then tried to create a shipment notification from the PO and the system would not do it but would allow me to do a goods receipt.

The system will not let me created a delivery from the SO.

I tried unchecking the ok tab in the SO and changed order type to normal but system would not allow this and now I cannot ok the SO again.

Please advise.
