Problem creating a sales order with DI API

Hi all,

I am trying to create a customer sales order using the DI API in SAP BO 9.2

I explicitly indicate the order amount for the corresponding line, however, SAP creates the order according to the price list associated with the customer.

How can I get SAP to save the amount that I established in the API and that is not associated with any price list?

C#
Documents Orden = this.SAPEmpresa.GetBusinessObject(BoObjectTypes.oOrders);
...
Orden.CardCode = cardCode;
...
Orden.Lines.Price = item.Price;
...Orden.Lines.Add();
Orden.Add();

Best regards,
Gustavo
