When Site/Warehouse is given on a Sales order header and we use the SALES ORDER>NEW>Purchase order or Direct delivery, it should copy this information to the created purchase order header to match the pass-thru or destination warehouse on the Purchase confirmation.

Currently, the purchase order header fields, including site/warehouse are copied from vendor defaults. A vendor that delivers to multiple warehouses will then have purchase confirmations with INCORRECT delivery addresses or otherwise have BLANK delivery address in standard D365 using the default values on vendor master. This is a big oversight in design of purchase order creation from sales order.

We should at least have the option to select on purchase order creation "use defaults from vendor master". But this would need to be configured in parameters for automatic PO creation as well. Best solution is to copy PO header inventory dimensions from the sales order header.
