Special order item added on a sales order created two purchase orders

Scenario: A special order item has been added to a sales order for two locations. As a result, two purchase orders were created by the system.

Item A preferred vendor Vendor 1

Sales Order
Sales Line # 1 Item A Vendor 1 Qty 1 Location 1
Sales Line # 2 Item A Vendor 1 Qty 1 Location 2

Solution: It is the system's normal behaviour that two purchase orders will be created if a special order item has been added on a single sales order with two locations.
