HI

You can communicate to SAP ERP in following ways

1.IDOC

2. RFC

3. SOAP

4. HTTP

5. ABAP Proxy ( Client and Server)

Proxy is mostly used for communication from XI and SAP ERP but this is a preferred solution in case you have data manipulation involved or customerization on SAP ERP

You can use RFC if there is a direct function module/BAPI call Async or Sync

Whenever you have Web Dyn Pro or BSP you can always use HTTP.

SAP ERP can expose Web services that will allow SOAP based communication with SAP XI

Search in SDN for various scenarios described above.

Thanks

SAP XI can communicate to SAP ERP with IDOC,RFC,PROXY. In some cases , File(OS level file transfer),SOAP(Web connectivity project) or HTTP even is used.

As per scenario i had experienced, PROXY is the best way to communicate with SAP ERP.It helps

1) To handle huge load.

2) The Proxy directly talks to the Integration Server.Thus no adapter is needed.

3) Proxies are programs that can convert XML to other data or vicevers. ABAP proxies convert abap data to XML or viceversa, depending if they are inbound/server or outbound/client.

Check this weblog for step by step :

For scenarios , u can search in SDN and find many of them.
