Cannot set item's price in new sales order using E-Commerce for ByDesign.

Question

Hello,
I'm working on a program to create zero value sales orders in my companies SAP system to help track warranties.  Every portion of this program is straight forward except for setting an item's list price to zero.  I'm using C# .NET.  Below is my code to create the SalesOrderMaintainRequestItem. Any advice would be greatly appreciated.
private SalesOrderMaintainRequestItem[] GetItems(Warranty warranty) // Custom Warranty Object
    int count = warranty.LineItems.Count; // Warranty object has an array of line items
    SalesOrderMaintainRequestItem[] item = new SalesOrderMaintainRequestItem[count];
    for (int i = 0; i < count; i++) // for each line item in the warranty object
        item[i] = new SalesOrderMaintainRequestItem();
        item[i].BuyerID = _ID;
        item[i].ItemProduct = new SalesOrderMaintainRequestItemProduct();
        item[i].ItemProduct.ProductID = new NOCONVERSION_ProductID();
        item[i].ItemProduct.ProductID.Value = warranty.LineItems[i].ReplaceWith;               
        item[i].PriceAndTaxCalculationItem = new SalesOrderMaintainRequestPriceAndTaxCalculationItem();
        item[i].PriceAndTaxCalculationItem.ItemMainDiscount = new SalesOrderMaintainRequestPriceAndTaxCalculationItemItemMainDiscount();
        item[i].PriceAndTaxCalculationItem.ItemMainDiscount.Rate = new Rate();
        item[i].PriceAndTaxCalculationItem.ItemMainPrice = new SalesOrderMaintainRequestPriceAndTaxCalculationItemItemMainPrice();
        item[i].PriceAndTaxCalculationItem.ItemMainPrice.Rate = new Rate();
        item[i].PriceAndTaxCalculationItem.ItemMainPrice.actionCode = ActionCode.Item01; // tried all the options for this one
        item[i].PriceAndTaxCalculationItem.ItemMainPrice.Rate.DecimalValue = 1.0M; // trying to set it as $1  just for testing, will be 0 when live
           // past tests that didn't work
        //item[i].PriceAndTaxCalculationItem.ItemPriceComponent = new SalesOrderMaintainRequestPriceAndTaxCalculationItemItemPriceComponent[1];
        //item[i].PriceAndTaxCalculationItem.ItemPriceComponent[0] = new SalesOrderMaintainRequestPriceAndTaxCalculationItemItemPriceComponent();
        //item[i].PriceAndTaxCalculationItem.ItemPriceComponent[0].Rate = new Rate();
        //item[i].PriceAndTaxCalculationItem.ItemPriceComponent[0].Rate.BaseDecimalValue = 1.0M;
        //item[i].PriceAndTaxCalculationItem.ItemPriceComponent[0].Rate.DecimalValue = 1.0M;
        //item[i].PriceAndTaxCalculationItem.ItemPriceComponent[0].Rate.CurrencyCode = "USD";
        //item[i].PriceAndTaxCalculationItem.itemPriceComponentListCompleteTransmissionIndicator = true;
        item[i].ItemScheduleLine = new SalesOrderMaintainRequestItemScheduleLine[1];
        item[i].ItemScheduleLine[0] = new SalesOrderMaintainRequestItemScheduleLine();
        item[i].ItemScheduleLine[0].Quantity = new Quantity();
        item[i].ItemScheduleLine[0].Quantity.Value = warranty.LineItems[i].ReplaceQty;
    return item;

Hi Joshua,
it's a long time ago and I hope you were able to solve your issue. For others who want to change prices in sales orders the following might be helpful:
It is not possible to set the price of a sales order in the create webservice call. You need to create the sales order first and then call the webservice a second time with actionCode="02" (Update).
The following is an extract from the sales order webservice documentation:
Node – PriceAndTaxCalculation
A price and tax calculation is the summary of the determined price and tax components for a business case. A specification of the general procedure for price and tax determination and valuation using attributes those are characteristic or relevant for the whole object.
Note: PriceAndTaxCalculation cannot be created but can only be modified. So this means that if the customer wishes to change the Discount or Freight charge, then the customer has to create the order first and then make a second web-service request to the update this sales order with the pricing information that is to be changed.
For the update you only need to send the ID of the sales order, the IDs of the items and the PriceAndTaxCalculation node.
The following would be an easy XML example for the update call:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:glob="http://sap.com/xi/SAPGlobal20/Global">
   <soapenv:Header/>
   <soapenv:Body>
      <glob:SalesOrderBundleMaintainRequest_sync>
         <SalesOrder>
          <ID>1234</ID>
            <Item actionCode="02">
               <ID>10</ID>
               <PriceAndTaxCalculationItem actionCode="02">
                  <ItemMainPrice>
                     <Rate>
                        <DecimalValue>5.00</DecimalValue>
                        <CurrencyCode>USD</CurrencyCode>
                     </Rate>
                  </ItemMainPrice>
               </PriceAndTaxCalculationItem>
            </Item>
         </SalesOrder>
      </glob:SalesOrderBundleMaintainRequest_sync>
   </soapenv:Body>
</soapenv:Envelope>
If you need further help with webservices or C#, let me know.
Best regards,
