You use valuated sales order stock if you want the goods movements to have corresponding postings in Financial Accounting (FI).
Sales order stock is assigned exclusively to a particular sales order and sales order item.
It cannot be used for other sales orders or sales order items.
Sales order stocks can be independent requirements. For this reason, the material components can only be used to manufacture the material ordered by the customer and are listed in a particular sales order item. The material manufactured can only be delivered to the customer in the context of the sales order item.
Sales Order Controlling – Planning

You can calculate the planned costs of the sales order using product costing with quantity structure (BOM and routing). Alternatively, you can use unit costing if the quantity structure has not been defined with a BOM and routing. This is typically the case for service products.
Within a unit costing, the system does not create a cost component split.
You can change a product cost estimate (with quantity structure) in the sales order item using the postprocessing function. In this case, you’ll get an explosion of the product costing as unit costing and you can change any items especially delete items or add new item. Using this function, the system does not write a cost component split. Because of this, you cannot use such a modified product cost estimate as the basis for valuation in Profitability Analysis (CO-PA).
Material Requirements Planning (MRP)

With multilevel Material Requirements Planning (MRP), you can calculate the independent and dependent requirements for the sales order.
You use valuated sales order stock if you want the goods movements to have corresponding posting in Financial Accounting (FI). Any goods movements from or to the valuated sales order stock debits or credits the consumer or the supplier as appropriate.
