• The cost in an invoice is taken over from the preceding document, in this case, the Sales Order.
• The Pricing Date of the Sales Order falls into the Valid From and Valid To Dates of the previously maintained Cost in the Product Master Data.
• Hence, the cost determined for the item in the Sales Order and consequently in the Invoice is 10.00 EUR.

You can check the Pricing Date and the Cost in the Sales Order as follows: 

1. Go to the Sales Orders work center.
2. Select the Sales Orders view..
3. Open the respective Sales Order.
4. Navigate to the Pricing tab.
5. The Pricing Date in our example is the 01.02.2025 which falls into the Inventory Cost maintained in the Product Master Data with the Valid From 01.01.2025 and the Valid To 28.02.2025.
6. Expand the Line Item
7. You can see that the Cost is 10.00 EUR in our example.

1. Understand that this is the expected system behavior.
2. The cost in an invoice is determined from the preceding document, not directly from the Inventory Cost.
3. If the Inventory Cost is updated after the creation of the Sales Order, the updated cost will not reflect in the invoice generated from that Sales Order.
