As for Y7-204944, it is accurate.
My AB date in PO is based on estimated arriving date to K. Win warehouse.
I believe he can break bulk and GR within 1 to 2 days upon receiving the shipment.
Therefore, it is quite safe to say GR will be done latest by 10 Feb, in which you will be able to create DN for delivery.
Let me know if you have further questions.
