Wsdl to xi to proxy

Question

Hello experts,
I have a scenario where i will be given a wsdl, that will be sent to XI and from there to proxy.
So from XI perspective, do i just add the wsdl as external definition , use the sender SOAP adapter and and XI adapter for proxy?
or do i have to genrate the wsdl file? from ID?...
since the wsdl is not hosted on XI, cai test the scenario using Altova?

1) Since Some X application is sending you a message using SOAP adapter...getting their wsdl is of no use
2) You need to develop a DT, MT, MI (OB Async)......here you can refer the wsdl (refer means just visually refer)
3) For the SAP side...create another DT (if needed), MT, MI (IN, Async)....i mentioned if needed....because you have an option of of developing your DT mentioned in pt.2 in such a way that you can use it at the receiver side also.....this will save you from creating the mapping....
4) If DTs are different then create a Mapping in XI...and corresponding Interface Mapping.
Save and activate all the objects....This completes IR part....
Now ID:
here you will need below objects:
1) A sender agreement
2) Interface Determination
3) receiver determination
4) Sender SOAP Channel
5) Receiver Agreement
6) Receiver CC with adapter Type as XI
Save and activate....
Now when this is done we need to generate the wsdl file of this interface and give it to the Sender application....then it is their duty to include it in their coding ....
