SAP PI 7.3 : Error during validation

Question

Hello Everyone,
I have an error during the validation, and I don't now where is the problem.
The error is :
     <SAP:Error SOAP:mustUnderstand="" xmlns:SAP="http://sap.com/xi/XI/Message/30"          
                                                xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">

          <SAP:AdditionalText>not used at the moment.</SAP:AdditionalText>
          <SAP:Stack>System error occurred during XML validation</SAP:Stack>
     </SAP:Error>
The XSD File for the validation is the following
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://site.be/Commandes" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://site.be/Commandes">

        <xsd:complexType name="Orders">
                <xsd:annotation>
                        <xsd:documentation xml:lang="EN">DT_Orders</xsd:documentation>
                </xsd:annotation>
                <xsd:sequence>
                        <xsd:element name="ligne" maxOccurs="unbounded">
                                <xsd:complexType>
                                        <xsd:sequence>
                                                <xsd:element name="Field1" type="xsd:string"/>
                                                <xsd:element name="Field2" type="xsd:string"/>
                                                <xsd:element name="Field3" type="xsd:string"/>
                                                <xsd:element name="Field4" type="xsd:string"/>
                                                <xsd:element name="Field5" type="xsd:string"/>
                                        </xsd:sequence>
                                </xsd:complexType>
                        </xsd:element>
                </xsd:sequence>
        </xsd:complexType>
</xsd:schema>
Can someone give me some input to help me to resolve this problem ?
Thanks a lot

Answer 1

How about a slight change to the xsd? Try with the following, it seems to work fine:
<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <xsd:element name="Orders" type="Orders"/>
   <xsd:complexType name="Orders">
      <xsd:choice minOccurs="0" maxOccurs="unbounded">
         <xsd:element name="ligne">
            <xsd:complexType>
               <xsd:sequence>
                  <xsd:element name="Field1" type="xsd:string" />
                  <xsd:element name="Field2" type="xsd:string" />
                  <xsd:element name="Field3" type="xsd:string" />
                  <xsd:element name="Field4" type="xsd:string" />
                  <xsd:element name="Qte" type="xsd:string" />
               </xsd:sequence>
            </xsd:complexType>
         </xsd:element>
      </xsd:choice>
   </xsd:complexType>
</xsd:schema>
You might also find this tool useful for testing such scenarios:

By the way - how did you get the xsd that you are currently using?
