SAP(Idoc) = XI = ThirdPart(WebService)

Question

Hello friends!
I have a problem with development of acknowledgement system with SAP(Idoc) <=> XI <=> ThirdPart(WebService)  scenario.
  My case:
Scenario looks like:
SAP(Idoc) <=>(Idoc adapter) XI (SOAP adapter)<=> ThirdPart(WebService)
  It must work this way:
SAP system send IDOC, then XI map it and send it via SOAP-adapter to third part webservice. Then webservice answer to XI with structure сontains "TRUE" or "FALSE",
and then XI must inform SAP ALE/IDOC system if current information from idoc was successfully added to webservice or not.
But how can I get it? As far as I understand ALE/IDOC system I have to create ALEAUD by myself, put status of idoc depends on webservice return and send ALEAUD idoc to SAP.
I'am right?

Hi,
You can use BPM for this Idoc--Soap Sync Process
Design objects:
Data type & Message Type
1) Import the IDOC and Later you import the Idoc, doble click on it a export it to your driver, next import it as External Definition for reason becouse if not, you wont be able to create a MI type synch with IDOC and genericResponse structure
2) Create data type for your Response Type of IDOC
3) Import the WSDL File For Request and the Response Type
4) Create the Message types according to the Data types which we created
Messgae Interface:
1) Outbound synchronous:
    output message will be ur idoc external definition file
    input message will be ur message type that u have created.
2) Abstract Outbound Synchronous:
    use the same as in Outbound Synchronous
3) Inbound Synchronous:
    input message will be ur request message of RFC/WebService
    output message will be ur response message of RFC/Webservice
4)Abstract Inbound Sunchronous:
    input message will be ur request message of RFC/WebService
    output message will be ur response message of RFC/Webservice
Mapping
Request Message Mapping:
b/w ur idoc external definiton and request message of RFC/WS
response Message Mapping:
b/w ur Response message of RFC/WS and ur message type
Interface Mapping
Import MI(abstract) of IDOC
Import MI of WS
select the mapping for request and response Tab
BPM
1) In container window define a variable named IDoc_ABS with category abstract interface and   
    type (select the MI of IDOC alone)
   define a variable named GenericRespnse_abs with category abstract interface and type (select         
   MI of genericResponse alone)
2) Create a Recieve Step --> in property message select the container you define before of idoc.
3) Define a Send Step--> mode synchronous
    select MI type abstract and sync (idoc and genericResponse)
    for property request message selects container Idoc_ABS
    for property response message selects container GenericRespnse_abs.
Save your Changes and thats all for BPM
*Configuration *
1) Create scenario
    Assign BS and create comunication channels with QoS (quality of service) type BE
2) Import your BPM
   Create a Receiver Determination
-->in the target service select the BPM. Save
-->In overview windown at foot windowns select MI IDoc_abs only. nothing else
Create a Receiver Determination
-->here the system who send data is BPM
-->in the target service select the BS of receiver system.Save
-->In overview windown at foot windowns select interface mapping and assing communication channel
what we do here. the flow is next
1) Receive data from sender system and send it to BPM
2) BPM call bs of target system (WS). how? because in interface determination you selected    
   before the interface mapping
