SOAP Scenario

Hi All,

We have a scenario where Sender will send IDOC XML as request and it should reach the Target R/3 system. In this case, we create a Webservice on XI server. As and when we receive a request from Sender, a response should go to Sender from XI ( not from R/3 system).How can we achieve this ?

Few questions:

as the sender is sending the IDOC XML and this is the structure which shuold be posted at R/3 system.No transformation is required.How can we achieve this mapping..Can we do Graphical mappingwhere in we perform direct mapping?

Please help.

Regards,

Venki
