SOAP Adapter Basics

Question

Dear Friends,
I need some crystal clear idea on SOAP Adapter Basics.
Sample scenario for my understanding:
When i send a Customer Request details webservices from a third party Webserver through sender soap adpater(Sync Interface) .
It reaches PI system and then reaches SAP ECC to fetch the customer details through Proxies.
In turn it gives customer repsonse details back to third party Webserver through the same sync Interface Soap Adapter.
1.I keen to know what is really happening between Sending Webserver and SAP PI system through Sender soap adapter.
2 When we use sender soap adpater do we really need to create webservice in Intgeration Directory, is it really mandatory.
3. I keenly like to know for the above scenario what exactly sender soap adapter is doing ...as step by step guide.

Answer 1

HI,
U have to follow the steps and provide the WSDL URL,message interface name, namepsace once u give all the information it will generate the WSDL file and at the end u will get the save option u save that WSDL on ur desktop.
Case one:
Webservice- XI- SAP system.
here remote client will act as sender. in this case from ID we create the WSDL file and send it to sender Webservice. This Sender will use the URL which we give while creating WSDL file from ID and send the message to XI.
Case two:
SAP System-XI-Webservice Receiver
Here Werservice provide the WSDL file and we import that WSDL file in XI and use as a data type. IN the SOAP receiver we will mention the WSDL file URL through which XI will send the data to Webservice.
