Integration Process/ccBPM - When to be used

Question

Hi All,
I have a scenario where i need to trigger the webservices in a third party java based system based on a value provided by SAP Workflow. Here two different web services are involved which needs to be triggred based on the response from the user.
Below are the steps that are involved in the entire process:
1. User request for an order and if material quantity is found, service 1 is triggered.
2. If the material quantity is not found, Service 2 is trigerred providing user with alternate options.
3. Now based on user response, if he agrees for alternate option, service 1 is trigerred.
Can any body explain how to do this in XI or perticularly in ccBPM.
Please let me know if you need further information
Help will be appriciated.
Thanks and best regards,
Kulwant

Hi Kulwant,
Though I had mentioned some steps earlier also, i am putting them again here for you:
Following are the steps for Integration Repository:
1) You would need an outbound proxy program to send data from SAP workflow. I am not proficient in SAP workflow but i know you can write some code in the workflow steps to send data to SAP XI, you get examples of writing an outbound proxy program in SDN.
2) Now your outbound proxy would trigger this particular scenario. It will bring input parameters for first java based webservice in XI.
3) You need to create data type, message type and outbound message interface for your SAP workflow structure. you need not create data type and message type for Java based web service as you would be directly importing it's wsdl and using it as your inbound message interface in message and interface mappings directly.
4) If the third party webservice is a synchronous one, then while creating the message mappings you need to create two message mappings for the 1st java based webservice, i.e. one for request and 1 for response, you would also need to create a response structure to create the mapping for 1st java based webservice's response or if you want to directly pass the output of 1st webservice as an input to the 2nd java based webservice, you can also do that.
5) Create a response mapping for the response of 2nd webservice in a similar fashion.
Confuguration / Integration Directory:
1) For sender side you do not need any communication channel. For receiver side you would need one as I mentioned earlier. To create a communication channel, you need to first create or import (if already created) a business system or a business service (you can read about these in help.sap.com, ask me if you need the link). I would suggest a business system as web service provider is a third party. How to do it:
ID--><your configuration scenario> --> Service without Party --> Business Service / Business system --> right click to create or assign.
Note: looking @ yesterdays posts, i believe it's fine for you to create just a business service only.
2) When you are done with this, you get a communication channel option created inside you business system or business service. Right click to create a communication channel. Give a name to it and press F4 to select the adapter type as SOAP. it would be a receiver. Read help.sap.com for more info on it.
Note: you would need two receiver SOAP communication channels for executing the 2 java based web services.
3) Rest of the mostly needed parameters i have already mentioned in my earlier posts for configuring the communication channel.
Hint: the target URL needed to configure the communication channel is usually there in <SOAP:action> tag in the wsdls of the respective web services.
4) Next create a Receiver determination --> Interface determination --> Sender Agreement --> Receiver Agreement
7) For receiver determination, you need to enter a business service / business system and the sender message interface. If you have chosen your own service then you need to register your message interface in the service. double click on the service name to do it. there are options to register inbound / outbound messages.
If you can use a conditional receiver determination to determine the user response and call the relevant web service based on that. At the 'edit receiver determination' screen there is a 'configured receivers' tab, where in condition field you can press F4. When you pess F4, a new screen opens, in left operand field, again press F4, a new screen would again open up, select 'Xpath' and there select the field in your sender (structure coming from workflow) structure, the field which contain the user choices (say 1 or 2 as mentioned by you).
Similarly, in the same receiver determination based on the condition, you can call either webservice 1 or 2.
8) For interface determination, you need to perform same steps as step no 7 also you need to enter your receiver service or business system.
9) In sender and receiver agreements you mention sender and receiver communication channels. Well in your case you need not make any sender agreement as you sending data from R/3 to XI directly.
if you configure these object completly, i believe you scenario should run.
In case of more queries, feel free to ask,
