Consider I have 2 warehouses A, B. In 'A' i have a product with 5 quantities in 'B' i have same product with 10 quantites. In sale order I choose warehouse 'B' and i want to deliver the product with 15 quantities but in 'B' i have only 10 quantities .So Odoo provides a solution for this. i.e. Setuping virtual warehouse (A+B)(https://www.odoo.com/documentation/14.0/applications/inventory_and_mrp/inventory/routes/concepts/stock_warehouses.html) in that i created a new warehouse 'C' and made A, B's parent location as C's stock location. Now i can deliver 15 quantities by choosing warehouse C in sale order no issues it works. But suppose if i want to deliver only 3 quantities from A or B it show's the out of stock warning in sale order line. Actually i have sufficient quantities in corresponding warehouses.
