yashina

I need to write export to external system using the WEB service,WSDL and XSD. I have never written an exchange using the WEB. Tell me where to start.
There is a method CreateOrderToSupplier (OrderToSupplier) and XSD
<xs: schema xmlns: tns = "http://www.aaaaaaa.com/Navision/package&quot; xmlns: xs = "http://www.w3.org/2001/XMLSchema&quot; targetNamespace = "http: // www .aaaaaaa.com / Navision / package "attributeFormDefault =" unqualified "elementFormDefault =" qualified ">
<xs: complexType name = "GoodsLine">
<xs: attribute name = "IDItem" type = "xs: string" use = "required" />
<xs: attribute name = "Quantity" type = "xs: int" use = "required" />
</ xs: complexType>
<xs: complexType name = "OrderToSupplier">
<xs: sequence>
<xs: element name = "GoodsLine" type = "tns: GoodsLine" minOccurs = "0" maxOccurs = "unbounded" />
</ xs: sequence>
<xs: attribute name = "IDSupplier" type = "xs: string" use = "required" />
<xs: attribute name = "Date" type = "xs: dateTime" use = "required" />
</ xs: complexType>
<xs: complexType name = "Result">
<xs: attribute name = "Error" type = "xs: string" use = "required" />
<xs: attribute name = "Result" type = "xs: boolean" use = "required" />
</ xs: complexType>
