Hi Joanne,
I suggest to use warehouse shipment page.
Open this page select location. After that click on Get source document it will show list released sales orders. those sales orders which have same location which is define on warehouse shipment page.
Select sales order click ok, it will add sales line on warehouse shipment line fact box, define qty. to ship and post document.
I fill with this process warehouse user not need to check sales order document.
Please verify the reply if it answers your query
Best Regards,
