How to create work order with defined address?

When I send this payload via the API

I do get a 200 OK response

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
soap:Body

</soap:Body>
</soap:Envelope>

However, the address that I enter in on the request does not get used. Instead, I see that some ShortLocation is used, I'm guessing that's a default somewhere? I'm not sure where that's coming from. How can I create a work order with a defined address of my choosing?

thanks,
Raul
