Unit Price on xml

Hello All:

Normally I used SDK's Document.line.Unitprice to set price before discount to the order entry. However via doing through xml's. The error message keep on sending back that rdr1.unitprice does not exist. O

Then I change the Unitprice tag to Price. While error message disappeared. The result however still shows system's default price as unitprice not the amount that I specified. Has anyone else had similar problem? Here a snip of my xml> and in SDK it's just simply

oCompany.XmlExportType = SAPbobsCOM.BoXmlExportTypes.xet_ExportImportMode;

odoc = ( ( SAPbobsCOM.Documents )( oCompany.GetBusinessObjectFromXML( sXmlFileName, SAPbobsCOM.BoObjectTypes.oOrders) ) );

My xml looks like something:

<?xml version="1.0" encoding="Windows-1252" standalone="yes" ?>
