InventoryNotificationIn Error: 'document not wellformed'

Hey Guys!

I'm trying to call the InventoryNotification Operation via SOAPUI but my message keeps hitting an error.

The error message i get is : Error while parsing an XML stream: 'document not wellformed'.

The message I'm sending is:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:n0="http://sap.com/xi/SAPGlobal20/Global">

<soapenv:Header/>

<soapenv:Body>

<n0:InventoryNotification>

<MessageHeader>

<CreationDateTime>2014-03-10T19:14:58Z</CreationDateTime>

</MessageHeader>

<InventoryNotification>

<ExternalID>IN-2</ExternalID>

<TransactionDateTime>2014-03-10T19:14:58Z</TransactionDateTime>

<Location>

<InternalID>PET200</StandardID>

</Location>

<InventoryChangeItem>

<InventoryChangeReasonCode>5</InventoryChangeReasonCode>

<InventoryMovementDirectionCode>2</InventoryMovementDirectionCode>

<ExternalID>002</ExternalID>

<Material>

<InternalID>8I01771045320101</InternalID>

</Material>

<Quantity unitCode="XBX">50</Quantity>

<QuantityTypeCode>XBX</QuantityTypeCode>

</InventoryChangeItem>

<SenderLastChangeDateTime>2014-03-10T19:14:58Z</SenderLastChangeDateTime>

</InventoryNotification>

</n0:InventoryNotification>

</soapenv:Body>

</soapenv:Envelope>

I downloaded the corresponding WSDL file directly from the ByD system that I'm calling.

I think I may need the values for schemeID, schemeAgencyID, schemeAgencySchemeAgencyID and maybe listID, listVersionID, listAgencyID, listAgencySchemeID, listAgencySchemeAgencyID to define the ValueTypes.

Where can i get these values?

It could be that there is another mistake that I'm not seeing.

Thanks for your help in advance!
