Hi,

Currently, In odoo we cannot do that, because we are taking sale orders to a particular warehouse, and that warehouse is configured under the other info tab, and the items are going to be delivered from that warehouse.

If the product is not available in Warehouse 1 we can take products from Warehouse 2 or Warehouse 3 using the resupply method, and we need to transfer those products to Warehouse 1.

We cannot deliver the products directly from the warehouses like your situation

Hope it helps
