Asynch WebServices: What does it mean?

help.sap.com -> Design and Configuration Time -> Configuration -> Additional Functions -> Defining Web Services

There is an information how to create WSDL from synch interface. Why only synch? Is there a way to get WSDL for asynch interface?

In SOAP Adapter section we see 2 types of WebServices (synch and asynch). SOAP Sender Adapter is the same as XI. It is needed only for additional settings.

Could somebody explain me how works synch and asynch webservices in XI ?

    Hi,

    You can create Asynch webservice, pls go thru the follwing thread

    Async Interface being called synchronously via Web service/SOAP

    while creating the sender communication channel for async webservices make sure that processing parmeter --> Quality of serivce as either "Exactly Once (asynchronous processing)" or "Exactly Once In Order (asynchronous processing using queues)"

    following threads will help you define the WSDL file,

    Hi,

    In the sender SOAP adapter channel don't set the processing mode parameter Quality of Service to "Best Effort".

    Hi Denis,

    >>>Could somebody explain me how works synch and asynch webservices in XI ?

    it's the same as with any other interface

    sync = send + wait for response

    async = send + forget

    Hi,

    Yeah, you can create a WSDL for async inteface also. Same procedure is to be followed.

    In asynch webservice there is no response part.
