Hi,
1.client not giving the WSDL file we are generate wsdl file
   Please check the steps to import/create WSDL for Receiver SOAP adapter on the guide below
   http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/40611dd6-e66e-2910-f383-e80fb44f9cd4?   QuickLink=index&overridelayout=true
2.create Data types and Message Types and Serivce interface outbound and inbound mode is synchronus and 2 mapping one for request and one for response and operation mapping .
coming to ID :
1. you need to create communication channel for SOAP and you dont need to create comm channel for PROXY.
2.receiver determination and interface determination and reciver agreement.
coming to R3 system you have to generate cilent proxy using T-code SPROXY then your esr objects are available. there you have to select Service interface outbound generate proxy and activate it.
go to SE80 transaction write a report to client proxy and call proxy in your report write select statement in order to fetch the data form the data base.
execte report provide valid input data and you will get response.
reagrds,
ganesh.
