SOAP to IDOC scenario

Question

Hello All,
I have a scenario where the sender system is outside our landscape and I need to post the PO data to SAP system using XI. I know its a SOAP to IDOC scenario but I am not given a wsdl but am given only a xsd and one XML as input. Can I use this XSD to create a sender message interface or is there any way I can convert the XSD to WSDL? Also, where should I give the path of the XML file in sender SOAP adapter?
And also I have to create a value mapping table where I have almost 4000 entries. Can any one let me know on how to create this?
I have browsed thru the SDN but havent found any information that I am looking for. Can anyone please help me on this.
I will be greatful if anyone can help me with Step by Step to SOAP to IDOC scenario.
Thanks and regards,
Neelima

I think what is this person asked to do is build an integration scenario using two business system
1. A business system understand web service technologies and also have a data definition they would like to use to communicate data with their business partner.
2. A business system which like to accept DATA in the format of IDOC.
So As long as we use XI as an integration framework, this is called SOAP to IDOC scenario.
I recomend to use the following steps to implement the integration need.
1. Understand the XSD data structure from the external service provider.
2. Using the external data definition create and outbound interface either SYNC or ASYNC format ( You have to discuss this with service provider for confirmation) in XI.
3. External service provider can use this outbound interface definition and associated data structure to send their data in their provided XML format to XI integration server.
4. Create an inbound service definition by using the XSD structure created for the IDOC you like to use.
5. XI integration server can use the inbound interface definition to pass the outbound interface message received once the outbound and inbound interface are connected using a configured scenario.
6. Using the outbound message type and inbound message type create a message mapping.
7. Using the message mapping create an interface mapping between outbound and inbound interface.
8. Create a WSDL from the outbound interface so that the service provider can use the service contract defined by the outbound interface in a web service enabled business system (Note: you have provided the data requirement in XSD format indicate that your business system is web service enabled). Make sure you are not getting fooled by the concept propose URL for the WSDL. You must provide the URL end point in created WSDL according to the following format.
http://<host>:<j2ee-port>/XISOAPAdapter/MessageServlet?
channel=<party>:<service>:<channel>
If the SOAP adapter channel belongs to a service without party, the address is as
follows:
http://<host>:<j2ee-port>/XISOAPAdapter/MessageServlet?
channel=:<service>:<channel>
9. Provide the WSDL to the service provider, ask them to use that WSDL to send data to your integration framework.
10. Configure the SOAP adaptor in sender mode, so that it can act as a end point to receive the XML data based on the XSD defined in the WSDL and convert the same to an XI document.
11. When u define the sender soap adaptor make sure you have selected the namespace and interface name same as the one you created for outbound interface.
Also recomend to read two How to guide related to web service and soap adaptor to complete your scenario.
