How to control ship-complete in STO process

Hi Experts,

The issue as follows and it is urgent.How can we convay the suplying plant to ship completely at PO Level.user don't want partial delevey in STO process.

how to ship all together in the STO process. I am going to place a purchase order in the system. In my understanding, system creates delivery automatically partially if there is some items are in stock NOT all together. However, this time the purchase order has to be shipped all together because it will go to the customer directly without unpacking when it is arrived in warehouse.

Thank you very much in advance.
