From SP 19 on XI 3.0 and SP 10 on PI 7.0, a File - RFC - File ( Asynch - Synch ) scenario can be done without a BPM.
Steps:
Integration Repository
The Integration Repository will be similar to any Synchronous Scenario ( say HTTP - RFC ) . 1 Outbound Synch message Interface and 1 Inbound Synch Message Interface.
Integration Directory
This is where a few differences lie, so let me take some time.
1. The Receiver Determination , Interface Determination will be the same as in HTTP - RFC synch scenario. Create the Sender File Adapter, Receiver RFC Adapter and Receiver File Adapter.
2. Sender Agreement will be for the Sender File Adapter. Sender Agreement uses the Synch Outbound Message Interface.
3. Receiver Agreement will be for the Receiver RFC adapter. Receievr Agreement will use the RFC as thge Inbound Message Interface.
4. We need to add a few modules in the Sender File Adapter.
Go to the Modules Tab of the Sender File Adater, and add the following modules in the same sequence,
Number - ModuleName - Type - ModuleKey
1- AF_Modules/RequestResponseBean - Local Enterprise Bean - 1
2- CallSapAdapter-Local Enterprise Bean - 2
3-AF_Modules/ResponseOnewayBean-3
Parameters
ModuleKey - ParameterName - ParameterValue
1 - passThrough - true
3-receiverChannel - Receiver File Adapter Name
3-receiverService - Receiver Business Service/ System
