Have you got an WSDL-Document?
Often you can find it at
With this document you can add a WebserviceReference to your BTProjekt.
BizTalk than creates a Porttype for the Webservice. Now you can create a Port using this Porttype (Webservice Porttype) and wire it with an Send shape and the correct Messages should be generated by BizTalk.
Now, you just have to do the right mappings or assign messages.
And that’s it.
