Hi
XI to CRM integration in detail
SAP CRM Integration with XI (To Cross Applications)
1)     Usually these kind of scenarios are SOAP - IDOC scenarios. The Webservice is used in EP that triggers the scenario. As usual standard IDOCs for CRM is used in the receiver side. There is also predefined XI content available for CRM integration and this is biggest advantage.
2)     If your integration policy is to make all integrations go thorugh XI and for all known advantages of XI i.e. central monitoring of integration data, loose coupling, you should go for XI. Else your webdynpro screens can always make use of CRM functionality exposed as webservices as model directly.
3)     CRM uses Bdocs to communicate. But if you want to test, then you can go for either Idocs (create a custom idoc) or you can create a RFC and you can test it. Then it is normal Idoc/RFC->XI scenario or vice versa
4)     There are multiple ways of integrating a CRM system with XI. You have to remember that your ultimate aim is to call the ABAP proxy method, passing the data as a parameter. This can usually be the last thing you call in another method or function module that first collates the data and packages it into the structure required by the proxy method.
5)     CRM has something called 'actions' that can be triggered on certain events. These actions then call a function module that gets processed.  Another route I have used is to have a batch job running periodically that runs a program. This program calls the proxy method.
Web Application (Webservice)=========è XI  ========è IDOC SAP CRM
Web Application (Webservice)=========è XI  ========è BAPI SAP CRM
Web Application (Webservice)=========è XI  ========è ABAP Proxies SAP CRM
Web Application (Webservice)=========è XI  ========è RFC calls to SAP CRM
Note:
If the volume of data is huge. Then go for idoc, as there might be standard idoc and if the volume of the data is not huge then go for BAPI.Go for a proxy only when if standard Idoc's or BAPI's are not available otherwise you are re-coding the existing things.
As CLAUS suggested try using BPCRM, as I believe they would have included creating sales order as it is very fundamental proceess of CRM products.
If you don't want to do any coding, then you will have to go for IDOCs/ BAPI. In this case all you have to do is the configuraion.
However, when you use Proxies, there will be a little coding required for calling the proxy. Its not much though. However, Proxies should get you better performance as they bypass the adapter engine.
In this case, as everything is standard, I would probably go by IDOC's.
You need to write client and server proxies.
Instead of coding for proxy if the Idoc is standard option.go for idoc tunnelling. As both your systems are SAP.That is the option’s the best.
i hope this will answer your question
