how to Buffer data in SAP MII when third party system is down.

Hi

We are using Web service call to post messages to WebSphere from MII.

Our requirement is like when WebSphere or any third party system is down we need to store that messages in SAP MII Data buffer and reprocess latter.

I have seen the below mentioned options in "Processing Type" under Data Buffering Configuration block in Web service call in MII

1. Synchronous processing.

2. Asynchronous Processing on Error.

3. Asynchronous processing.

Please let me know how to keep all the failed messages in SAP MII Data buffer in this scenario and explain the scenario how to use these three options.

Thanks in advance.
